Akzo Nobel: Science-based Targets Drive Innovation across the Value Chain
Sustainability has been an important part of the way we do business for decades. To help us maintain and build on our strong heritage, we’re always innovating and delivering fact-based results. Our approach to doing sustainable business is therefore an integral part of our commitment to People. Planet. Paint. – our promise that we’ll keep innovating to address key global issues – and goes beyond our own operations. That’s why we have set carbon reduction targets of 50 percent by 2030 (baseline 2018) for our whole value chain, validated by the Science Based Targets initiative (SBTi) in 2021. Collaborating with our partners across the value chain and increasing our portfolio of sustainable solutions are key levers to achieving our science-based carbon reduction targets.
To measure our progress on sustainable solutions, we co-developed the Sustainable Product Portfolio Assessment with the World Business Council for Sustainable Development (WBCSD). It’s a fact-based approach that measures the sustainability characteristics of our product portfolio and groups it into three categories: sustainable solutions, performers, and transitioners. Sustainable solutions currently make up approximately 40 percent of our total portfolio and we aim to grow this even further to more than 50 percent by 2030. Our reporting on sustainable solutions is verified by an external auditor, ensuring our framework is transparent and comprehensive.
Green buildings are an example of how our products create sustainable communities. The historic Hudson Yards development in New York City is the largest U.S. private real estate development. The ongoing project completed two towers at 10 and 30 Hudson Yards, with the impressive glass and steel structure of 30 Hudson Yards features the company’s high-performance architectural powder coatings, while 10 Hudson Yards uses our industrial coatings. Most of the aluminium on the larger tower is coated with the company’s Interpon D3000 Fluromax metallic powder coating, including the highly prominent first five stories. The remaining louvers and some of the ornamental metals are coated with our TRINAR liquid coating. The shorter tower at 10 Hudson Yards features our TRINAR coatings on all visible aluminium – both exterior and interior. Our powder and liquid coating products make this Manhattan neighborhood development a LEED-certified sustainable community (Leadership in Energy and Environmental Design – a global green building certification program) and help the buildings last longer.
We’ve also launched our Ceram-A-Star CS 1050 Select offering for LEED-certified buildings. This is our latest development using COOL CHEMISTRY coatings that are applied on metal roofing. The result is a sustainable building material that lowers air conditioning costs, reduces peak energy demand, and helps to mitigate urban heat island effects. When applied on roofs and walls in a hot climate, COOL CHEMISTRY coatings reduce air conditioning costs by up to 15 percent.
In our food packaging coatings, we have developed new waterborne BPANI coatings that have a lower embodied carbon footprint and help our customers to optimize their productivity – thus helping them to reduce the carbon footprint in the value chain. One of these sustainable solutions is our Aqualure™G150 that has allowed our customers to smoothly transition from epoxy-based lacquers while meeting performance requirements.
We continue to innovate and develop more sustainable solutions that reduce our carbon emissions in our value chain and help achieve our SBTi approved carbon reduction targets, while at the same time deliver on the high-quality standards that our customers expect from us.

allnex: Sustainability in our DNA — New Bio-based Aliphatic Urethane Acrylate
Since the 1960s, allnex has been an inventor of sustainablt resin solutions, such as waterborne industrial coating resins, polyester powder resins and UV curable technologies. allnex has deep roots in sustainability and is actively working to reduce our environmental footprint, focusing on the impact of our operations, technologies and product offerings. The radiation curing technology, part of the allnex portfolio, is characterized by an energy-efficient profile along with a portfolio of low- to no-VOC products. The technology uses energy-induced radical polymerization, which results in immediate curing of the coating that can be achieved with ultraviolet light or electron beams. Alternative curing mechanisms can be obtained in combination with peroxides and/or in the presence of elevated temperatures.
Because of its performance, high throughput and sustainable profile, this technology is widely used in markets such as industrial wood, packaging, inks and plastic coatings. The replacement of less environmentally friendly technologies, such as solvent-based and acid-catalyzed systems that release volatile organic compounds into the atmosphere, has contributed to the growth rate and interest in this technology. In particular, this shift has affected industrial wood coatings such as furniture and flooring, a trend driven by brand owners and actively supported by allnex.
While radiation curing already offers a sustainable profile, allnex is continually pushing the boundaries to further reduce its environmental footprint by investing in more efficient production processes, increasing the durability of its products and continuing to develop a portfolio of resins that contain safer chemicals and incorporate bio-based building blocks to ultimately reduce its overall carbon footprint.
One of these efforts led to the development of EBECRYL®4690, a bio-based energy curable aliphatic urethane acrylate. This one-of-a-kind, patented product contains 30% C14 (measured according to ASTM D6866) and is tin, solvent and BPA-free. The product combines excellent weathering resistance, high reactivity, a strong abrasion and chemical resistance with a very low yellowing. It is therefore ideal for both clear and pigmented coatings for exterior and interior applications, as well as for coatings for furniture, kitchen cabinets, floors and panels. The carbon footprint reduction of the material can be estimated as >500 g CO2/kg.
When developing the product, allnex considered other key market elements such as performance, price positioning and raw material availability. We can proudly confirm that the performance and price positioning are very close to the fossil analogue, while the availability of the key bio-based raw material has been detached from fossil value chains plagued by availability issues. Thus, we offer not only a sustainable product, but also a product that meets other market requirements: availability, performance and cost. At allnex, we believe that sustainability should not be a burden, rather a source of great opportunities, which we once again have demonstrated with this development.

ANGUS: Improving Indoor Air Quality with Amino Alcohols
Driven by environmental, health, and safety concerns, coating technologies have undergone a dramatic shift in the past few decades. Most of this movement has been driven by the reduction of VOCs and other hazardous materials in coating formulations. The continuous development and improvement of waterborne technologies has enabled many solvent-based systems to be replaced with waterborne chemistries that contain significantly lower VOC content than their solvent-based counterparts. VOC levels have been pushed even lower by the development of low-VOC and zero-VOC water-based formulations.
With the use of amino alcohols based on ANGUS chemistry, it is possible to also create zeroVOC and low emissions coatings, as well as functional coatings that improve indoor air quality. Coatings can be formulated using either AMP-95 or AEPD VOX 1000 to meet zero-VOC requirements in the United States/Canada and Europe/ China, respectively. These same products also have no or low emissions, which can enable coating formulations to qualify for green label programs.
A continuation of this trend emerging in the global coatings industry has been focused on the development of functional coatings that not only limit emissions of VOCs into the environment but extract and remove VOCs that have originated from other sources. A functional coating with VOC remediation capability could improve indoor air quality and provide a means to scavenge VOC emissions from sources that have proven to be more challenging to address.
Formaldehyde emitted from carpets, furniture, electronics, household cleaners and other synthetic materials is one of the most common indoor air pollutants and can pose a significant short- and long-term risk to human health. With increasing regulatory and consumer focus on improving indoor air quality, one of the most effective solutions to reducing indoor formaldehyde levels is through chemical remediation or scavenging systems.
ANGUS’ TRIS AMINO™ Crystals amino alcohol is proven to provide high-efficiency formaldehyde scavenging performance in impregnated activated carbon air filtration systems. These unique multifunctional chemistries can also be used at low dosage levels to add formaldehyde scavenging performance to existing waterborne architectural paint and construction applications, helping improve indoor air quality without requiring major reformulation work. TRIS AMINO can be easily formulated into waterborne coatings and is highly effective at low use levels as scavengers of airborne formaldehyde without negatively impacting final paint performance.
While TRIS AMINO has superior formaldehyde scavenging potential, AEPD VOX 1000 can offer additional functionality as it not only scavenges formaldehyde but can also adjust solution pH, disperse pigments, and develop a synergistic effect with registered biocides leading to extended shelf life. These chemistries provide an easily accessible pathway to advance the evolution of environmentally friendly coatings by creating functionality that improves indoor air quality within homes, schools, offices, and other buildings.

Clariant: No Room for Slip-Ups — Creating the Right Feel for Wood
Wood coating manufacturers are raising their ambitions to offer more sustainable solutions without compromising performance. They’re keen to answer consumers’ calls for hardwood flooring and furniture to take on the safety and wear demands of busy households while being as natural as possible in look, feel and materials. Clariant’s customers are using its bio-based Ceridust® micronized powders and waxes for surface modification to fulfil their requirements for sustainability and multifunctional performance.
Scratch and rub resistance, matting effects and slip/coefficient of friction properties are all-important attributes when it comes to protecting and enhancing wood in consumer households. Ideally, bio-based additives should provide benefits comparable to conventional non-bio-based options to be most attractive. With this consideration in mind, Clariant supports its coatings customers in finding the most appropriate renewable additive for their particular needs. Within Clariant’s portfolio, the Ceridust Vita product line is 100% solid, easy-to-incorporate, and based on non-food competing raw materials with 98% Renewable Carbon Index and free of VOC.
In recent flooring applications, for example, Clariant’s Ceridust 8090 Vita and 8091 Vita are enabling coatings’ manufacturers to achieve in-demand performance and aesthetic properties from bio-based solutions. The two additives have different particle sizes that lend a different ‘touch’ to the wood. The coarser Ceridust 8090 Vita creates a protected and smooth surface with the pleasant feel of untreated wood. At the same time, it increases coefficient of friction (COF) – great for anti-slip properties – in combination with outstanding scratch resistance performance in water-based formulations. The finer grind Ceridust 8091 Vita combines smoothness with very high scratch resistance and offers matting effects similar to standard waxes. It also increases COF and, with its package of benefits, is enabling manufacturers to formulate more sustainable coatings with top quality.
Both Ceridust 8090 Vita and Ceridust 8091 Vita are proven suitable for UV and waterborne systems and show improvements in scratch resistance, even outperforming standard micronized waxes without reducing the COF. This is valuable for floor coatings where for safety reasons it’s important to avoid a low COF, or where a manufacturer would like to use materials based on renewables to imitate wooded structures, or to make the floor more resistant against wear.
These innovative developments, which have been awarded the Clariant EcoTain® label for their outstanding sustainability and world-class performance, show that it is possible for coatings manufacturers to meet their targets when formulating more sustainable coatings. Clariant is constantly evolving its portfolio of additive solutions to provide customers with key sustainability benefits to move them forward.
Covestro: High Performance Aliphatic Hardener Takes the Next Step in the Sustainability Journey
Something exciting has happened in the polyurethane world. For multiple decades, aliphatic polyurethane coatings have long been recognized as the high-performance option for critical applications such as automotive, industrial, and infrastructure due to the inherent strength of the polyurethane bond and the excellent properties it imparts. These proven hardeners, while fulfilling the durability and aesthetic demands of the market, have been traditionally formulated with fossil-based raw materials. However, aliphatic hardener technology has taken the next step forward: Covestro has developed a new aliphatic hardener, the first in the market in over 30 years, that has replaced a significant amount of the fossil-based carbon content with over 70% of bio-based material.
The polyisocyanate, Desmodur® eco N, is a pentamethylene diisocyanate (PDI) based trimer and yields excellent properties similar to hexamethylene diisocyanate (HDI) trimer. A unique feature of this bioderived material is that it utilizes non-edible corn starch which is enzymatically converted by specially developed microorganisms in a highly efficient manner. The Desmodur® eco N version has been developed to be similar to existing HDI-trimer for use in solventborne topcoats and the Bayhydur® eco N version is hydrophilically-modified to have better compatibility in waterborne systems.
With the creation of this biobased aliphatic hardener, formulators have begun to use this new building block within current developments. Two examples are the use of the crosslinker in a two part automotive OEM exterior clearcoat. The coating needed to meet current stringent testing specifications with no sacrifices in performance. It’s very important to note that moving to bio-based materials does not have to equate to reduced performance. These two automotive manufacturers desired the sustainability attribute of a bio-based aliphatic hardener while retaining the proven performance value of a polyurethane clearcoat.
Chemists are also evaluating the use of this unique hardener in the formulation of abrasion and chemical resistant concrete floor coatings. The coating can be classified as a polyurethane or a polyaspartic depending on which resins are used, but in either case the expectation is for similar floor coating properties such as durability, stain and chemical resistance, and long-term color and gloss retention. However, it is not enough to include the biobased trait while allowing other environmental concerns to suffer. So, the new hardener has a similar viscosity profile as traditional products which allows for the formulation of ultra-low VOC construction coatings – continuing the downward sustainability desire for lower VOC.
Similarly, the high biobased hardener is of interest to coatings companies that formulate fluid-applied reflective roof coatings. For this application, the final coating supports two sustainability drivers – biobased content and energy efficiency. In particular, two component aliphatic polyurethane roof coatings are not only durable, they also have the all-important quality of reflecting sunlight’s IR rays rather than absorbing them – initially as well as years after application. Since there are existing aliphatic polyurethane roof coatings available with 22 to 25% range using resins, this biobased hardener would allow for sustainable roof coatings with a bio-based content in excess of 50%.
Definitely a step in the right direction!
Dow: Climate Protection, Circular Economy, Safer Materials
As a materials science company, our ambition is to be the most innovative, customer centric, inclusive and sustainable materials science company in the world. Our purpose is to deliver a sustainable future through innovation, expertise and collaboration with our partners. To achieve our sustainability ambitions, we are focusing our efforts around three areas: Climate Protection, Safer Materials and Advancing a Circular Economy. Here is a sample of exciting technologies and solutions that Dow’s Coatings & Performance Monomers business offers, aligned with Dow’s sustainability priorities.
Dow aims to reduce emissions by five million metric tons by 2030 — a 15% reduction versus our 2020 baseline. This target is the next step in our broader commitment to achieve carbon neutrality by 2050. To support this goal, Dow’s Coatings & Performance Monomers business, is targeting a 30% reduction in emissions by reducing our footprint, increasing use of renewable power and expanding the portfolio of lower carbon binders and additives.
To advance a circular economy, Dow will enable the collection of one million metric tons of plastics to be re-used or recycled through direct actions and partnerships, and by 2035, all products sold into packaging applications will be reusable or recyclable.
RHOBARR™, Dow’s portfolio of waterborne barrier coatings for paper-based substrates, enables brand owners, converters and mills to develop new paper packaging formats to meet sustainability commitments and consumers’ expectations for recyclable and repulpable packaging. An exciting upcoming product launch is RHOBARR™ 325 Barrier Dispersion, which provides excellent barrier to hot and cold liquids, strong heat sealability, and excellent repulpability. In paper cups, RHOBARR 320™ Barrier Dispersion provides sustainability benefits through the use of barriers that are up to 70% thinner and have 50% lower carbon emissions than incumbent coatings. When repulped, up to 99% of the paper fibers can be recycled.
For our architectural and industrial coatings customers, we offer more than 150 binders and additives that are APEO-free and that enable low to ultra-low VOC paints and coatings. All of our new product innovations are APEO-free and our aim is to have our entire portfolio be APEO-free by 2030. Our products are enabling our customers to remove materials of concern from end-products. Here are two illustrative examples:
- To get oil, grease and water barrier, fluorochemical additives (e.g., PFAS) have been commonly used in food packaging containers. The use of RHOBARR™ 214 Acrylic Emulsion in paper packaging eliminates the need for PFAS additives.
- We spend more than 90% of our time indoors. Indoor air can be 2-3 times more polluted than outdoors and a known indoor air pollutant is formaldehyde, an irritant and a probable human carcinogen. Indoor paints that feature FORMASHIELD™ binders, capture formaldehyde, thus helping improve indoor air quality.
Sustainability at Dow is broad in scope, innovative in character and designed to create a positive impact on society and the environment. Let’s formulate together for a more sustainable future!
Dunn-Edwards: Water Conservation in a Water-Based Industry
From the beginning of Dunn-Edwards, being green has been at the core of our business practices. Our concern for the environment has always been expressed in simple terms such as “make the most of what you have” and “avoid letting anything go to waste”. This business model not only extended to ingredients and product performance, but also how products were manufactured and an awareness of water usage and potential for water reusage. At Dunn-Edwards, we’ve taken water conservation seriously by reusing production rinse water wherever possible – an act which allows us to reuse over 180,000 gallons of water a year.
Paints and coatings are, by nature, environmentally beneficial for the protection they provide to our built environment, and water-borne coatings offer substantial benefits over solvent-borne coatings in areas of air quality, and health and safety. However, with the transition to water-borne coatings, the water demand required by the industry has been no small figure. The ability to reuse water has become increasingly important and offers the industry an opportunity to conserve and optimize the resource.
Paint production at Dunn-Edwards’s manufacturing facility can be done at a scale of 500 gallons to 12,000 gallons for a wide variety of flat and non-flat coatings – with capabilities for over a dozen product formulas being manufactured in a single day. Cleaning of all batch-making equipment is incredibly important to ensure the appearance and performance of our final products meets quality standards. In our efforts to conserve water, our facility is capable of segregating cleaning water by product sheens, and this water can be reused in products specifically designed for their integration. By reusing cleaning water whilst ensuring quality production output, Dunn-Edwards has saved over 900,000 gallons of water in the last five years – a number that will only continue to increase as the years go on.
Water conservation is just one of the ways that Dunn-Edwards is committed to being eco-efficient. For more information about our Greener by Design business model and philosophy, and our Phoenix Manufacturing Facility, visit www.dunnedwards.com.

Henkel: Innovative Pretreatment Process Drives Sustainability in Auto Industry
As a leading global provider of adhesives, coatings and sealants, Henkel invests in researching and developing solutions that will help its customers be more sustainable through changes in process, materials, and packaging.
As sustainability requirements across the auto industry began to take shape in the early 2000s, Henkel began researching pretreatment alternatives that would reduce reliance on heavy metal
phosphates. A zinc phosphate metal pretreatment process has been the industry standard for many years, however research led Henkel to a zirconium oxide-based conversion coating, which offers a more sustainable alternative.
Henkel’s innovative process first made its debut in 2007 on the Ford F150 truck. Today, more than four million vehicles are pretreated every year with Henkel’s Next Generation Metal Pretreatment
process. The innovative process reduces the steps required from seven in a conventional metal pretreatment procedure to four, significantly reducing the automaker’s carbon footprint. Environmental benefits also include:
➢ Elimination of heavy metal phosphates
➢ Up to a 90 percent reduction in sludge generation
➢ Up to a 50 percent reduction in water usage
In 2021, the process earned Henkel second place in the category of sustainable process in the 2021 Altair Enlighten Awards*, the auto industry’s recognition of game-changing innovations in
sustainability and lightweighting.
Henkel’s pre-treatment process supports the incorporation of more aluminum and other lightweight materials into vehicle design. Sustainable solutions like this play a key role in reducing the weight — or “lightweighting” — of both gas-powered and electric vehicles (EVs) and help the auto industry address environmental regulations around fuel efficiency and emissions, while providing
comfort and safety for the driver.
Currently, electric vehicles are roughly 30 percent heavier than traditional gas-powered vehicles. This is largely due to the weight of the battery, which spans the length of the vehicle body. The use
of more lightweight materials in EV manufacturing helps to offset the weight of the battery and increase driving range — a key selling point for consumers.
Henkel is committed to driving sustainability across industries through new innovative products and services. The company’s ambitious goals include becoming climate positive by 2040 and reducing the environmental footprint of its production facilities by 65 percent by 2025.

* The Altair award specifically recognizes Toyota’s use of the Henkel process in production of the 2021 Tacoma and Tundra trucks (under the name Pallumina as trademarked by Nihon Parkerizing).
ICP: Reflective White Coatings Offer Savings and Sustainable Benefits over Roof Tear-offs
Roof tear-off is a costly, time-consuming, disruptive process and there is often a better way to protect structures, save energy and avoid serious leaks. In most cases, a roof restoration system will be more cost effective than a re-roof that uses new layers of insulation, and it will be easier to maintain. Choosing a white elastomeric, acrylic or silicone roof coating that reflects harmful ultraviolet (UV) rays also improves the energy efficiency of buildings and helps prevent deterioration that shows up as cracks and splits in the membrane.
With roof coatings, waterproofing solutions, pavement products and more for commercial and residential construction needs, APOC® is a trusted industry name and one of the newest members of the ICP family. Cool roofs drastically reduce surface temperatures, meaning roof membrane life is extended, building occupant comfort is improved and cooling costs are reduced.
Dark roof surfaces can become 90° F hotter than the most reflective white surfaces. This increases stress to the entire roofing system, results in higher heat transfer into the building and contributes to an urban heat island effect whereby heat is absorbed and reemitted back into the surrounding air, causing local temperatures to rise faster and remain hotter even after sundown (in other words, a city will absorb and re-emit more heat from the sun than a rural area). The cumulative effect is increased energy demand, air pollution, greenhouse gas emissions, heat-related illnesses and more.
APOC engineers Cool Roof Restoration Systems that deliver high solar reflectivity and thermal emittance to reduce roof surface temperatures. In turn, building internal temperatures and air conditioning needs are diminished. These solutions are recognized by the Cool Roof Rating Council (CRRC) as the highest rated roof coatings in the industry, with many meeting Energy Star requirements for certified roof products that reflect more of the sun’s rays.
Decades of innovation have resulted in a broad portfolio of solutions that restore and protect both smooth and gravel-surfaced built-up roofing (BUR), mineral granule cap sheet, EPDM rubber membrane, select white single-ply systems and most metal roofs. For APOC, coating development is about giving contractors more cool roof options that provide sustainable benefits and lower energy costs in conditioned spaces.
ICP’s acquisition of Gardner-Gibson’s APOC, Gardner®, Black Jack® and Dyco® brands deepens a lineup of industrial coatings, adhesives and sealants that protect against unwanted or uncontrolled air and moisture in a variety of climates. ICP is committed to helping commercial building contractors and remodelers achieve the best outcomes and solve problems using more energy-efficient, environmentally responsible products.
Restoration can increase the service life of a roof up to 15 years and may be repeated for as long as the structure of the roof remains sound. A white reflective coating can deliver the added advantages of reduced heat buildup, longer roof life and less environmental impact. Durable, highly reflective coating systems that provide additional reinforcement on susceptible parts of the roof like vertical seams, fasteners, curves, penetrations and around the perimeter offer many cooling benefits to building owners.

RPM: Hydrocoat Ablative Antifouling Bottom Paints Reduce VOC Emissions & Wasted Energy
Pettit® Paint, a brand of Modern Recreational Technologies, Inc. (MRT)*, has made significant efforts to bring fresh innovation to the recreational boating industry in a variety of ways. One of the most notable advancements has been the introduction of an environmentally conscious, yet highly effective antifouling bottom paint line, Hydrocoat®.
Hydrocoat is one of Pettit’s most popular lines of ablative antifouling bottom paints and features water-based technology, a low-VOC formulation, and thin-film technology. Hydrocoat is available in two formulations, Hydrocoat and Hydrocoat Eco, which offer antifouling protection that is effective against hard and soft growth.
Hydrocoat’s environmental benefits extend well-beyond the coating itself. Marine engines operate under extreme conditions and expel up to 10 times the pollution, consume up to 10 times the fuel, and experience a more rigorous maintenance schedule when compared to non-marine engines. Hydrocoat’s self-polishing, ablative paint film reduces drag and drastically improves a vessel’s operating efficiency when compared to traditional hard antifouling coatings. These improved efficiencies not only reduce emissions and improve fuel economy, but also reduce maintenance time and the amount of chemicals used to perform this maintenance.
Hydrocoat Eco features a metal-free biocide package and includes ECONEA® and Pyrithione Zinc. This biocide package is effective against a broad spectrum of fouling organisms including barnacles, hydroids, mussels, oysters, tube worms, algae, and slime. Hydrocoat Eco offers cleaner colors and can be applied to a wider variety of substrates, including aluminum.
Pettit’s Hydrocoat line has pioneered water-based, copper-free antifouling coatings in the recreational boating industry. The Hydrocoat line of water-based antifouling coatings and experienced strong acceptance and adoption throughout the industry.
In addition to product performance, the plastic packaging contains up to 50% post-consumer resin and requires less energy to produce, reduces carbon emissions and uses fewer components than standard pails. Its triple-seal cover eliminates the need for a gasket, so the entire container can be recycled without the need to separate components.
*MRT is a subsidiary of RPM International Inc., a provider of specialty coatings, sealants, building materials and related services. In addition to Pettit, RPM has a diverse product portfolio with hundreds of market-leading brands that protect, beautify and enhance the built environment – from homes and workplaces, to infrastructure and precious landmarks.

Tex-Cote: COOLWALL® Coatings Reduce Both Energy Costs And The Urban Heat Island Effect
What if you knew you could save anywhere from 4% to 27% in energy costs savings all with just an application of a wall coating? For decades, cool roofs have been used by owners and specifiers to reduce sunlight absorption and reduce energy costs. They can be made of highly reflective paint, a sheet covering, or highly reflective tiles or shingles. Until 2004, cool roofs were the primary solution to reduce sunlight absorption. Seeing a need to reduce heat uptake in walls, Tex-Cote LLC, a leading manufacturer of specialized exterior wall coatings, developed the COOLWALL® coatings system.
Tex-Cote’s original COOLWALL® patent was issued in 2004, bringing the first-ever COOLWALL® coatings system to market. Through solar-reflective “cool walls,” the system reduces the absorption of sunlight by the building envelope and allows for darker and deeper tone colors to reflect heat buildup, much like white and light colors.
Infrared reflective technology is not unique to cool roofs or cool walls. It is used by the military as the key innovation to reduce heat absorption on planes, tanks, and other military vehicles. Tex-Cote’s proprietary COOLWALL® product also incorporates Kynar® into the formulation to provide long-lasting coating durability and minimize the reduction in long-term reflectance values from biological growth and dirt pickup.
This coating system is especially helpful in combatting the urban heat island effect in U.S. cities, which have higher temperatures than outlying areas. Research by scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory demonstrates the effectiveness of “cool walls” in reducing energy consumption and increasing cost savings. They conducted a study that modeled several different types and ages of homes, retail stores, and office buildings across California and the country and found that sunlight-reflecting walls can often save as much, or some cases more energy than sunlight-reflecting roofs.
This research examined structures throughout the county and concluded that in warm U.S. cities from Miami, Florida, to Albuquerque, New Mexico, “cool walls” could cut annual heating, ventilation, and air conditioning (HVAC) energy costs by as much as 11% for stand-alone retail stores, 8.3% for single-family homes and 4.6% for medium-sized office buildings. The study also found that Single-family homes across all California climates, a potential energy cost savings of 4% to 27%.
The benefits of reflective wall coatings are now being recognized and endorsed by a number of building codes and environmentally focused rating systems. In addition to The U.S. Green Building Council’s new LEED pilot credit SSPC154, Ashre 90.1-2019, Cal Green, International Energy Conservation Code, International Green Construction Code, and Green Globes all have references, guidance, or protocols related to the use of reflective, or cool walls.
Since 2004 the COOLWALL® coatings system has been both laboratory and time tested across the country for both its energy savings and long-term impact in reducing the urban heat island effect.
