US 5,326,816 A · Room temperature curable silicone composition

Abstract

A room temperature curable silicone composition comprising (A) an organopolysilethylenesiloxane represented by the following general formula (1): ##STR1## wherein R.sup.1 to R.sup.4 each represent a monovalent hydrocarbon group having 1 to 10 carbon atoms, and n is an integer of 10 or over, (B) an organosilane or an organosiloxane having at least two hydrolyzable groups in the molecule, and (C) at least one ultraviolet absorbing agent and antioxidant. The cured product formed from this composition exhibits good soil resistance for a long period of time and soiling of the surface of the cured product and its surroundings due to dust or the like in the air can be obviated effectively.
