Room temperature curing silicone elastomer composition

A room temperature curing silicone elastomer composition that is comprising

• (A) 100 parts by weight of diorganopolysiloxane comprising (a) a diorganopolysiloxane having a viscosity at 25.degree. C. of 0.1 to 1,000 Pa.s and having both molecular chains terminals blocked by silanol groups and (b) a diorganopolysiloxane having a viscosity at 25.degree. C. of 0.1 to 1,000 Pa.s and having one terminal of the molecular chain blocked by a silanol group and the other terminal blocked by a trialkylsiloxy group, the molar ratio of diorganopolysiloxane of (a) to diorganopolysiloxane of (b) being in the range of 1.0:0.3 to 1.0:3.0;
• (B) 0.1 to 20 parts by weight of organosilane represented by the general formula R.sup.1.sub.4-a Si(OR.sup.2).sub.a wherein R.sup.1 and R.sup.2 are monovalent hydrocarbon groups having 1 to 20 carbon atoms and a is 3 or 4 or a partial hydrolyzate thereof;
• (C) 5 to 30 parts by weight of solid organopolysiloxane resin of R.sup.3.sub.3 SiO.sub.1/2 units wherein R.sup.3 is a monovalent hydrocarbon group having 1 to 20 carbon atoms or a hydroxyl group) and SiO.sub.4/2 units, where the molar ratio of R.sup.3.sub.3 SiO.sub.1/2 units to SiO.sub.4/2 units is in the range of 0.5:1.0 to 1.2:1.0;
• (D) 0.01 to 20 parts by weight of a curing catalyst, and
• (E) 0.5 to 2 parts by weight of higher fatty acid.
