One-part moisture curable composition

摘要

A room temperature-curable one-part moisture curable composition exhibiting excellent storage stability as well as good adhesion is provided. The cured product produced thereform has excellent rubber elasticity as well as high strength. The one-part moisture curable composition comprises (A) an organic polymer having at least one reactive silyl group in the molecule, (B) an isocyanate compound having at least one isocyanate (NCO) group bonded to secondary or tertiary carbon in the molecule, and (C) a latent curing agent. The latent curing agent (C) is preferably a ketimine wherein a branched carbon atom or a ring member carbon atom is bonded to alpha position of at least one of the ketimine carbon or the ketimine nitrogen.
