Abstract
A room temperature curable organopolysiloxane composition comprising (A) a diorganopolysiloxane end-capped with a hydroxy or alkoxy group, (B) a silane crosslinker, (C) an aluminum hydroxide powder surface treated with a silane, siloxane or silazane, and (D) a platinum catalyst is shelf stable and smoothly extrudable prior to curing, and cures into a silicone rubber having long-lasting self-extinguishing properties. The composition is best suited as an adhesive to electrical and electronic parts.
Claims6
A room temperature curable organopolysiloxane composition comprising
- (A) 100 parts by weight of a diorganopolysiloxane end-capped with a hydroxy or alkoxy group and having a viscosity of 100 to 500,000 mPa·s at 25° C.,
- (B) 0.1 to 30 parts by weight of a silane compound having at least three hydrolyzable groups each attached to a silicon atom in a molecule or a partial hydrolyzate thereof,
- (C) 50 to 300 parts by weight of an aluminum hydroxide powder surface treated with at least one compound selected from the group consisting of a silane, siloxane and silazane and having an average particle size of up to 50 μm, and
- (D) an amount of a platinum catalyst to give 1 to 200 ppm of platinum metal based on the weight of component (A).
