Abstract
There is provided a paintable room temperature curable polyorganosiloxane composition which is comprised of a silanol-terminated polydiorganosiloxane, an aminoxy functional organosilicon compound, an inorganic filler and a monohydric unsaturated alcohol containing a carbon-to-carbon triple bond and a hydroxyl group bonded with a primary or secondary carbon atom.
Claims8
A room temperature curable polyorganosiloxane composition comprising:
- (A) 100 parts by weight of a silanol group-terminated polydiorganosiloxane having a viscosity at 25.degree. C. of 100-200,000 cSt;
- (B) 0.1-30 parts by weight of an aminoxy group-containing organosilicon compound containing an average of more than 2 organoaminoxy groups per molecule;
- (C) 5-300 parts by weight of an inorganic filler, and
- (D) 0.01-10 parts by weight of a monohydric unsaturated alcohol containing a carbon-to-carbon triple bond and a hydroxyl group bonded with a primary or secondary carbon atom.
