ABSTRACT:
A flame resistant low-smoke hot melt adhesive composition, particularly useful for adhering facings to building products and thermal insulations, is disclosed. The composition consists essentially of, in parts by weight, 11-45 parts of high (at least 200.degree. F.) melt point paraffin wax, 10-14 parts of halogenated (preferably chlorinated) microcrystalline or paraffin wax, 0.3-10 parts of halogen scavenger, 5-20 parts of a flame suppressant synergist, 5-20 parts of a low temperature resistant vapor barrier barrier elastomer, and 0.5-10 parts of smoke suppressant. Preferably the composition will also contain a carbon dioxide donor/filler. The material is not tacky when cold, can be readily reactivated by heating, and can be applied in discrete units.
