A moisture curable polyurethane composition comprising (A) a urethane prepolymer having two or more isocyanate groups in the molecule, (B) an inorganic filler as a storage stabilizer, (C) an N-silylamide compound represented by the formula (1), (D) an epoxy resin, and/or (E) a moisture latent curing agent, and a moisture curable epoxy resin composition comprising (D) an epoxy resin, (C) an N-silylamide compound, and (E) a moisture latent curing agent.wherein R<1 >is a hydrocarbon group having 5 to 21 carbon atoms optionally containing a heteroatom, provided that when n is 0, 1 or 2, R<1>s may be the same or different; and R<2 >is an alkyl or alkoxy group having 1 to 3 carbon atoms; and n is 0, 1, 2 or 3.The moisture curable compositions are excellent in storage stability and thixotropic properties, have high curing rates at the time of working, and can give rise to cured products having excellent mechanical properties such as tensile strength. |
