Life-Cycle Assessment of Architectural Coatings: A World Without Preservatives

multi-color circle
Preservatives themselves play a crucial role in enhancing shelf life, ensuring the product does not spoil before being used, and protecting the dried coating film from biologic growth. The primary goals of the LCA were to determine the environmental impacts and benefits that wet-state and dry-film preservatives play in architectural coating systems and see how reducing, eliminating, or replacing certain...

Web Exclusive: Powder Coatings Protect the New York City Skyline

Hudson Yards in New York City
Powder coatings on the market today are far more versatile than the first products developed decades ago. In addition to a traditional smooth appearance, today’s powder coating technology enables the formulation of coatings that provide sparkle, color travel, special effects, and textured surfaces while providing increased protection against corrosion and weathering. Access to the ever-widening array of powder coating technologies...

Achieving a Factory-Applied Finish at Home

New Home, Vinyl Siding, Architectural Asphalt Shingle Roof, Real Estate
Vinyl siding is often chosen by homeowners because it comes as colored panels with a high-quality finish and doesn’t require more work once it is installed. That factory-applied finish does not last forever, however, and then building owners are faced with the choice of replacing the siding to get that type of appearance or painting on site, which cannot quite...

Exterior surfaces experience degradative environmental conditions, such as intense UV exposure, rain, and temperature swings, leading to deterioration. Coatings are low-cost solutions offering decades of protection and preventing significant repair costs for buildings. The coating must withstand UV, mitigate water damage, and express the flexibility required to maintain adhesion to dimensionally unstable substrates (i.e., wood) as they undergo thermal expansion...

Towards a Comprehensive Understanding of Dirt Pickup Resistance

Calm and serene lake between complex surroundings
The fouling of exterior coating surfaces by dirt is no simple matter. The process is complex, dynamic, and varies in length and time. It also includes a range of confounding particle transport, attachment, and release mechanisms. While complex, strategic, multiscale testing and analysis combined with particle and surface science fundamentals can be used to isolate the dominant mechanisms. In this...

Factors Affecting Sealer Performance on Concrete

Modern city square floor and beautiful sky at sunset
It is often assumed that solvent-based sealers give better performance than water-based formulations on concrete because the solvent-based sealers are thought to better penetrate into the concrete matrix. In practice, it can be difficult to measure actual penetration of a sealer into concrete, as dyes and colorants used to highlight the sealer may show different migration properties than the polymeric binder....
