ABSTRACT:
A method and adhesive system for bonding at least two elastomeric substrates together. The method comprises subjecting the substrates to a priming treatment followed by applying to the primed substrates a heat-curable polyurethane adhesive composition comprising an isocyanate-terminated prepolymer and a polyhydroxide compound. The surfaces of the substrates so treated are contacted and subjected to heat-curing to bond the substrates together.
