Elastomeric roof coating formulated with alumina trihydrate that provides fire retardant properties. Alumina trihydrate acts as a flame retardant and smoke suppressant because of its thermodynamic properties. When exposed to heat, it will absorb about 280 cal/gram before liberating water vapor. This endothermic dehydration cools the coating and dilutes with water those combustible gases that do escape. Component of FM approved fluid applied reinforced roof recovery system designated ARS-1FR.
