Hot melt adhesive containing hydroxyl-functional ethylene-vinyl acetate and blocked polyisocyanate |
摘要 |
A composition for a cross-linkable hot melt adhesive is provided and is formed by an ethylene-vinyl acetate copolymer containing primary hydroxyl functions and a blocked polyisocyanate. This composition when associated with a tackifying resin, which can also serve as blocking agent of the polyisocyanate, is a cross-linkable hot melt adhesive. The adhesive is used at a temperature at least equal to splitting temperature of the isocyanate functions of the polyisocyanate. The temperature at which such adhesives retains adherence can reach about 200 DEG -220 DEG C.
