Abstract:
A room temperature curable silicone rubber composition comprising:(A) 100 parts by weight of an organopolysiloxane represented by a general formula (I) shown below, with a viscosity at 25Â° C. of 100 to 500,000 mm2/s, â€ƒwherein, each R1 represents, independently, a substituted or unsubstituted monovalent hydrocarbon group, and n represents a number which results in a viscosity at 25Â° C. of 100 to 500,000 mm2/s, (B) 1 to 100 parts by weight of a surface-treated reinforcing fine silica powder with a specific surface area as measured by a BET method of at least 50 m2/g, and a tap density of 0.2 to 0.4 g/ml, which has undergone treatment with an organosilicon compound to produce a quantity of surface carbon of at least 2.5% by weight, and (C) 0.01 to 10 parts by weight of a tin compound-based curing catalyst.
