  • Publication number: 20180319824
    Abstract: The present invention provides: a novel organic titanium compound having an effect as an adhesion promoter by itself; a production method of such organic titanium compound; and a room temperature-curable resin composition containing such organic titanium compound both as a curing catalyst and as an adhesion promoter. Provided are an organic titanium compound represented by an average composition formula (I): Ti(OR1)4-a(Y3Si—A—O—CO—CH?C(O)R)a (wherein R1 represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 12 carbon atoms, R represents a substituted or unsubstituted monovalent hydrocarbon group having 1 to 12 carbon atoms, A represents a divalent hydrocarbon group having 3 to 6 carbon atoms, Y represents a hydrolyzable group, and a represents a number satisfying 0<a<4); a production method of such organic titanium compound; and a room temperature-curable resin composition that contains a room temperature-curable resin.

  • Patent number: 9434817
    Abstract: The invention is a room-temperature-curable resin composition including a phosphazene skeleton-containing organosilicon compound shown by the following general formula (1). This provides a room-temperature-curable resin composition which is curable in short time, free from generation of an odor due to the catalyst, free from a heavy environmental load; and has sufficient hardness, elongation at shear, and tensile strength after curing.
