Document Type and Number:
WIPO Patent Application WO/2005/108500
Kind Code:
A1
Abstract:
[PROBLEMS] To provide a curable composition containing a non-organotin catalyst and having good adhesiveness. [MEANS FOR SOLVING PROBLEMS] A curable composition comprising an organic polymer (A) having a silicon-containing group capable of causing crosslinking through the formation of siloxane likages and at least one catalyst (B) selected from among titanium catalysts, aluminum catalysts, and zirconium catalysts, characterized in that the stress at 50% elongation is 0.01 to 0.20MPa as determined by mixing 100 parts by weight of the polymer (A) with 1.5 parts by weight of tin octylate, 0.25 part by weight of laurylamine, and 0.6 part by weight of pure water, deaerating the mixture by centrifuging, pouring the resulting mixture into a polyethylene form so carefully as not to make the mixture bubble, aging the mixture at 23&ring C for one hour and then at 70&ring C for 20 hours to form a cured sheet having a thickness of 3mm, punching a No.3 dumbbell according to JISK6251 from the cured sheet, and subjecting the dumbbell to tensile test (rate of pulling: 200mm/min) at 23&ring C and 50% RH.
