Abstract:
1. A room temperature curable silicon group-containing polymer composition, comprising: (A) a reactive silicon group-containing polymer obtained through a urethane reaction between polyoxypropylene polyol whose number average molecular weight is 500 to 50,000 and γ-isocyanate propyltrialkoxysilane, having a main chain being substantially composed of polyoxypropylene, and having a reactive silicon-containing group represented by a formula: (wherein the R 1 s are the same or different and each represents an alkyl group having 1 to 4 carbons) at an end of the main chain, and based on 100 parts by weight of said reactive silicon group-containing polymer; (B) 0.01 to 10 parts by weight of a curing catalyst; and (C) 0.05 to 25 parts by weight of hydrolyzed and condensed product of amino group-substituted alkoxysilane.
