Abstract:
1. A liquid silicone rubber coating composition, comprising: (A) 100 parts by mass of at least one organopolysiloxane containing two or more alkenyl groups bonded to silicon atoms within each molecule, (B) at least one organohydrogenpolysiloxane containing at least two silicon atom-bonded hydrogen atoms within each molecule, in sufficient quantity that a number of silicon atom-bonded hydrogen atoms within the composition is within a range from 1 to 10 per silicon atom-bonded alkenyl group within the component (A), and a molar ratio of a number of silicon atom-bonded hydrogen atoms within the component (B) relative to a total number of silicon atom-bonded hydrogen atoms within the entire composition is within a range from 0.5 to 1, (C) an effective quantity of at least one addition reaction catalyst, (D) 0 to 50 parts by mass of at least one finely powdered silica with a specific surface area of at least 50 m (E) 0.1 to 10 parts by mass of at least one organosilicon compound containing an epoxy group and a silicon atom-bonded alkoxy group within each molecule, and (F) 0.01 to 5 parts by mass of at least one organoaluminum compound represented by formula (3): wherein each R independently represents an unsubstituted or substituted monovalent hydrocarbon group of 1 to 20 carbon atoms.
