SafeCoat® Latex Intumescent Coating is a single-component, latex intumescent fire retardant coating suitable for interior applications on a variety of combustible substrates, including SPF (spruce/pine/fir) plywood, oriented strand board (OSB), wood trusses, and wood-frame construction, where flame spread ratings of 25 or less (“Class A” or Class 1) and low smoke developed ratings are required. It limits flame spread by expanding to several times the original dry film thickness when exposed to heat. This expanded material forms a char that insulates the substrate from heat and reduces available oxygen at the surface. It provides a "Class A" flame spread rating of 25 or less as tested according to ASTM E84 and CAN/ULC S102. SafeCoat® Latex is certified with UL/ULC listings for this classification.
