ABSTRACT:
A modified polyurethane adhesive composition characterized by its improved viscosity and high initial bond strength contains an isocyanate-terminated prepolymer or a fully reacted polyurethane and a carbamate ester which is compatible and not reactive with the prepolymer or polyurethane. The resultant adhesive is suitable for laminating many types of substrates. In a preferred embodiment the prepolymer is employed with the carbamate ester in a reactive hot-melt adhesive for use in bonding flexible substrates.
