Flamex PA is a clear, un-pigmented additive for creating a flame retardant paint layer. Add one full jar of Flamex PA to a US gallon (3.79L) of water based paint to make your paint coating flame retardant. Flamex PA is compatible in most latex or vinyl acrylic paints but always test with your specific paint choice. Do not use Flamex PA with metallic paints as the metal pigments may react and tarnish or corrode. Flamex PA does NOT alter the flammability of the substrate being painted but only adds a retardant treatment that slows the spread of fire along the surface.
Rosco Flamex PA has been pre-measured and should be added to a single US Gallon (3.79L) of paint. Once combined, the paint/Flamex mixture can be diluted as desired but the dry paint film must be no less than 4 mil in thickness. The effectiveness of a fire retardant barrier is dependent on both the fire retardant additive and the thickness of the coating. Flamex PA is not intended to be used in place of other Flamex products. Where possible, always treat the substrate material using the appropriate Flamex product.
8 oz. of Flamex PA mixed into one gallon of paint will treat approximately 300 square feet (28 square meters) of material as per paint manufacturer's guidelines. Flamex PA has been approved for use by the California and New York City Fire Marshall and has been tested according to ASTM E84 Class A. Store Flamex products in non-metallic containers. When metal sprayers are used, they should be thoroughly cleaned immediately after use, including nozzles and accessories. Avoid use of metal buckets or paint containers when possible.
