<p><P>PROBLEM TO BE SOLVED: To provide a room temperature curable poly-organo-siloxane composition being excellent in water-resistance and especially improving reduction of adhesion property and mechanical strength due to warm temperature dipping. <P>SOLUTION: The composition includes (A) 100 pts.wt. of poly-organo-siloxane having a molecular chain terminal blocked by a hydroxyl group or a hydrolyzable group and having viscosity at 23°C of 20-1,000,000 mPa s, (B) 1-400 pts.wt. of calcium carbonate being subjected to surface treatment by a fatty acid having a branched alkyl group or its salt as a filler, and (C) 0.001-10 pts.wt. of a curing catalyst. Further, the composition preferably contains (D) 0.05-10 pts.wt. of aminoalkylalkoxysilane. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
