Abstract:
The present invention provides a curing catalyst for an organic polymer or an organopolysiloxane, which has a high safety and a practical curing speed, and improves the adhesion of a cured product to a substrate, and can be produced at low cost.
An aspect of the present invention provides a curing catalyst [B] for an organic polymer or an organopolysiloxane, which is used for curing an organic polymer [A1] or an organopolysiloxane [A2] having a reactive hydrolyzable silicon-containing group, wherein the catalyst [B] contains a titanium compound [B1] represented by the following formula and a secondary amine compound or a tertiary amine compound [B2]. (R1—O)nTi-A4-n (In the formula, R1 is a hydrocarbon group having 1 to 10 carbon atoms, and A is a carboxylic acid residue, and n is 1 or 2.)
