Abstract
A curable resin composition comprising an oxyalkylene base copolymer having at least one silicone atom containing group to the silicone atom of which a hydroxyl group and/or hydrolyzable group is attached and which is cross-linked through formation of a siloxane bond.
Claims14
A sealant composition for use with alkyd paints, comprising:
- a) a moisture curable polymer of the formula (I):
- where a+b=3 and a is 1, 2 or 3, Q is a monovalent hydrocarbon radical having from one to forty carbon atoms where each X is independently a hydrolyzable group selected from the group consisting of methoxy, acetoxy, and oxime and m and n are non-zero integers chosen so that the weight average molecular weight ranges from about 5,000 to about 45,000;
- b) a condensation catalyst;
- c) a silane crosslinking agent;
- and
- d) a liquid paraffinic hydrocarbon processing aid comprising greater than 40 wt. % cyclic paraffins.
