Abstract
Disclosed is a novel curable silicone-based aqueous emulsion composition suitable as a surface-coating composition for an air bag base cloth and capable of exhibiting excellent adhesion to the substrate cloth and imparting the surface-coated cloth with excellent flexibility and flame retardancy. The aqueous silicone emulsion composition is a uniform blend which comprises: PA1 (A) 100 parts by weight of an aqueous base emulsion of an organopolysiloxane consisting of PA2 (A1) from 10 to 70% by weight of an organopolysiloxane having 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, PA2 (A2) from 0.01 to 10% by weight of an anionic surface active agent, and PA2 (A3) the balance of water; PA1 (B) from 1 to 60 parts by weight of an aqueous dispersion consisting of PA2 (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 PA2 (B2…
