LATENT AMINO GROUPS AND ISOCYANATE GROUPS COMPRISING POLYURETHANE PREPOLYMERS, METHOD FOR THEIR PRODUCTION AND THEIR USE

摘要

A one-component polyurethane composition is described that comprises a latent curing agent bonded to the prepolymer, from which curing agent aldehyde is liberated upon curing. Said aldehyde comprises two phenyl groups. By the specific design of the polyurethane composition, the application characteristics as well as the ageing resistance of the cured polyurethane are improved.
