Flame retardant masticis a white gray thick jelly, made of epoxy resin, organic solvent, film forming agent, plasticizers, flame retardant, and fillers. It is mainly used as vapor barrier layer for cold insulation and moistrue proof material for building roof. It has all advantages of asphat based mastic, such as better formability, wider service temperature, better cold resistance, due to its main film forming matter is organic polymer.This Fire Retardant Masticcan not melt or crack easily in hot or cold temperature, and its application totally same as asphat based mastic.
