1K PUR Dispersion with Comparable Performance to 2K Waterborne Coating

New Residential House; Architectural Asphalt Shingle Roof, Vinyl Siding, Gables
Experimental To increase the performance of a 1KWB PU to the level of a 2KWB PU, an intensive development program was undertaken. Its goal was to develop a 1KWB PU with higher film hardness (e.g., >2H pencil gouge hardness) and with superior chemical resistance (e.g., detergent, nitric acid, and mortar). The study examined various kinds of high molecular weight polyol,...

Hollow Thermoplastic Microspheres in Elastomeric Cool Roof Coatings

Hollow Thermoplastic Microspheres in Elastomeric Cool Roof Coatings
 Hollow ultra-low density thermoplastic microspheres can be used as filler in elastic waterproof/cool roof coatings to improve a number of important properties of the coatings. Micron-sized hollow microspheres have a surprisingly strong effect on reflecting solar radiation and reducing the temperature of cool roof coatings. Results from solar reflectance measurements show that the coating system filled with hollow microspheres reflects...

The National Coil Coating Association’s Color Experiment: Potential for Converting to CIE Color Space and ΔE2000

Samples of metal tiles roof in the building store
Over the decades, the North American coil coating industry has depended on the use of Hunter color space to measure and control color. The National Coil Coating Association (NCCA), now in its 57th year, recognizes that many others are using CIE* color space for day-to-day color control, and that DE2000 is considered a superior methodology to describe color difference, rather...

Corrosion Prevention for Historical Preservation

Repairing Vukovar rebar closeup
Buildings can be considered historical for many different reasons. They may have played a critical role in the distant history of a local region or nation, or may be relatively recent, yet still represent an important time or event. Coatings are an important component of any building preservation and/or restoration project given that they are used to protect and beautify...

Nine Years Following the Great Recession: The State of the U.S. Paint and Coatings Industry

Financial data analysis graph showing search findings. Selective focus. Horizontal composition with copy space.
Writing in these pages in 2015,* I stated that “The years between 2014 and 2019 will be good ones,” and so they have been—but “good” is a relative term, at least in the context of economic health. In June 2009, the Great Recession, which had lasted for 18 months and caused American households to lose $16 trillion in net worth,...
