Abstract:
An aqueous silicone emulsion composition which is a uniform blend of the ingredients comprising:(A) 100 parts by weight of an aqueous base emulsion of an organopolysiloxane consisting of(A1) from 10 to 70% by weight of an organopolysiloxane having silicon-bonded monovalent hydrocarbon groups and at least two hydroxyl groups bonded to the silicon atoms in a molecule, in which from 0.01 to 10% by moles of the monovalent hydrocarbon groups are alkenyl groups,(A2) from 0.01 to 10% by weight of an anionic surface active agent, and(A3) the balance of water;(B) from 1 to 60 parts by weight of an aqueous dispersion consisting of(B1) from 5 to 50% by weight of a solution containing, in an at least partly water-miscible organic solvent, from 10 to 90% by weight of a reaction product between an amino group-containing hydrolyzable organosilane compound or a partial hydrolysis product thereof and a polycarboxylic acid anhydride, and(B2) from 50 to 95% by weight of an aqueous colloidal silica dispersion containing from 10 to 50% by weight of colloidal silica particles; and(C) from 0.01 to 10 parts by weight of a curing catalyst.
