OIL-IN-WATER SILICONE EMULSION COMPOSITION

摘要

An oil-in-water silicone emulsion composition comprising (A) 100 mass parts of a polyorganosiloxane that contains in each molecule at least two groups selected from the group consisting of the silicon-bonded hydroxyl group, silicon-bonded alkoxy groups, and silicon-bonded alkoxyalkoxy groups, (B) 0.1 to 200 mass parts of a colloidal silica, (C) 0.1 to 100 mass parts of an aminoxy group-containing organosilicon compound that contains at least three silicon-bonded aminoxy groups in each molecule, (D) 0.1 to 50 mass parts of a surfactant, and (E) 10 to 200 mass parts water. Such oil-in-water silicone emulsion composition that contains little low molecular weight silicone can form, even without the use of a tin catalyst, a cured film that exhibits a satisfactory strength and a satisfactory adherence to substrate, through the removal of the water fraction.
