ABSTRACT:
A heat curable hot melt adhesive system is disclosed. The system uses an epoxy-crosslinking ethylene polymer component, a tackifier compatible therewith and an epoxy crosslinking agent having an epoxide functionality of at least 2. The ethylene polymer component may be either an ethylene copolymer of an .alpha.,.beta.-ethylenically unsaturated carboxylic acid, or an ethylene copolymer of an ethylenically unsaturated alcohol used in combination with a dicarboxylic acid anhydride. The dicarboxylic acid anhydride and/or the epoxy can be encapsulated to inhibit premature crosslinking. The formulation is applied to a substrate surface as a hot melt at a moderate temperature, and subsequently cured by heating the adhesive composition to a higher curing temperature.
