Abstract
Abstract A liquid polymerizable material which may be used, for instance, for the coating of wood or other substrate, which material, when cured, is fire-resistant and protects the substrate. The material cures without application of heat and is formed from methyl methacrylate monomer, a hydroxy alkylacrylate or diacetone acrylamide monomer, a chlorinated hydrocarbon, an antimony compound, a zinc compound, a filler, and a catalyst-promoter system.
