Abstract
Provided by the invention is a water-base silicone composition suitable for the surface treatment of, in particular, rubber articles as the substrate to impart the surface with excellent abrasion resistance and lubricity. The composition comprises, as dissolved or dispersed in an aqueous medium: (A) 100 parts by weight of a diorganopolysiloxane, e.g., dimethylpolysiloxane, terminated at each molecular chain end with alkoxy or hydroxyl group and having a specified degree of polymerization; (B) 0.01 to 10 parts by weight of an organotrialkoxy silane compound such as methyl triethoxy silane; (C) 1 to 10 parts by weight of an organoalkoxy silane compound containing an amido group and a carboxyl group in the molecule such as a reaction product of 3-amino-propyl triethoxy silane and maleic anhydride; (D) 1 to 10 parts by weight of an organoalkoxy silane compound having an epoxy group in the molecule such as 3-glycidoxypropyl trimethoxy silane; and (E) 0.01 to 10 parts by weight of a curing catalyst.
