The use of this new, novel, waterborne clear coating system allows for the true wood visual to show while providing improved fire retardancy performance, and significantly reducing the smoke developed. Existing technologies currently use organic components for a "soft" char that will protect the underlying substrate, but the coating will continue to burn, creating a large amount of smoke. Another, "hard" char, type of coating is used with a silicate system and expanding graphite powder to create a protective layer that reduces the smoke generated, but must be pigmented due to the graphite used in the system. Armstrong's new, unique coating system provides equal, or better, coating performance than the "hard" char coatings, while allowing for a clear visual. In addition, Armstrong has now certified that a 25/50 (flame spread index/smoke developed index) rating in the E84-18b Tunnel Test has been achieved numerous times and can be used in return air plenums, which is a first for a wood coated product.
