Room temperature-curable organopolysiloxane composition.

摘要

A room temperature-curable organopolysiloxane composition is disclosed, comprising (A) 100 parts by weight of an organopolysiloxane terminated with a silanol group or an alkoxy group, (B) from 0.1 to 30 parts by weight of an organosilicon compound containing more than 2, in average, of hydrolyzable groups bonded to the silicon atom per molecule, (C) from 0.5 to 50 parts by weight of a hydroxyl-containing organic compound capable of swelling a polyolefin resin and, if desired, (D) a requisite amount of a curing catalyst. The composition exhibits satisfactory adhesion to an untreated polyolefin resin to provide sufficient adhesive strength for withstanding practical use.
