One-part, room temperature moisture curable resin composition

Abstract

This invention provides a one-part, room temperature moisture curable resin composition which comprises a ketimine prepared by reacting a ketone having a substituent at α position and a polyamine having at least two amino groups within its molecule wherein α position is methylene, and a main polymer which is an epoxy resin and/or a modified silicone having at least two hydrolyzable alkoxysilyl groups in its molecule, and which exhibits good shelf stability and high curing rate once taken out of the container, and which may further exhibit flexibility; a one-part, room temperature moisture curable resin composition which exhibits good shelf stability and curability as well as wet surface adhesion or initial thixotropic properties; a silicon containing compound having ketimine group whose reaction with the epoxy resin during the storage is prevented by the presence of a bulky alkyl group near the ketimine group and which exhibits good shelf stability and curability, and its production method; a one-part, room temperature moisture curable resin composition containing said silicon containing compound adapted as a latent curing agent which exhibits good shelf stability and short curing period once taken out of the container; and a novel method of ketimine synthesis.
