In the 1960s a coating system formed by overcoating a molten hot-melt coating with a latex paint was conceived as an answer to a search by the wood siding industry for a primer to improve paint performance on its product. Performance testing, including weather exposure, had a positive outcome, but circumstances prevented commercialization. Thirty years later, the originator of the concept undertook a more thorough investigation. This article is a public a report on coating system composition and performance.
The introduction of new substrate wetting additives improves the spreading capacity of emulsion paints. Also the effectiveness in filling the crevices/pores of concrete substrates is highlighted by the results of accelerated efflorescence or alkali block testing.
Dura Industries, reputable color developer and applicator of liquid PVDF and powder coatings, teamed up with Valspar, frontrunner in the international coil and extrusion architectural coatings industry and part of Sherwin-Williams Extrusion Coatings, to create and coat the renowned façade of the Smithsonian National Museum of African American History and Culture. For this specific project, Dura Industries implemented a hand-painted five-coat system for the first time in the company’s history.
The former Spruce Goose hangar that was built by aircraft innovator Howard Hughes in 1945 in Playa Vista, California, is being renovated for use as office space. The project’s architects were looking for an infrared heat reflective coating and a dark color that will last on the building and not fade, and provide energy savings.
These micronized innovations are based on renewable raw materials in different particle size distributions that support customers’ ambitions to offer more sustainable solutions to industrial markets without compromising performance.
In early 2013, Grace Matthews published a white paper titled North American Architectural Coatings: The End Game? In it, we discussed the recent acceleration in architectural coatings mergers and acquisitions (M&A) and likened the "Big Four" - at the time Sherwin-Williams, PPG, Masco and Valspar - to the final table of a poker tournament.
The acquisition was an opportunity for Axalta to enter the wood coatings business, a market size of more than $8 billion globally, with an industry-leading product portfolio and a customer-trusted business with a strong reputation.
It takes a strong and imaginative mind coupled with in-depth technical knowledge and an artistic flair to think outside the box and create a truly unique residential design. A newly completed house in Los Angeles showcases a dramatic and elegant exterior feature that commands attention.
The concept of an organic coating system consisting of a hot-melt coating (also known as thermoplastic coating), overcoated with a water-thinned coating while in the molten state, was explored by the development of solvent-free shop primers for forest product-based exterior architectural components. These shop primers with and without commercially available finishes were compared to selected commercial coating systems on various substrates by weather exposure in multiple locations. The concept is in its infancy, but coatings developed are commercially practical with performance equal or superior to conventional coating systems of recognized quality. Suggested applications of the concept include road marking and interior trim. The field is open for exploitation.
