ANTIFOULING SILICONE EMULSION COATING COMPOSITION, PROCESS FOR PRODUCING THE SAME AND ANTIFOULING ARTICLE COATED THEREWITH

摘要

An antifouling silicone emulsion coating-composition comprising following components (A), (B), (C) and (D), an amount of the component (C) incorporated being in the range of 5 to 80 % by weight relative to the total solid contents in the composition: (A) partially hydrolyzed organosiloxane with a weight-average molecular weight of 600 to 5,000 (determined using a polystyrene calibration curve), represented by the average formula (I): R<2>aSiOb(OR<1>)c(OH)d wherein R<1> and R<2> represent a monovalent hydrocarbon group; a, b, c and d are numerals satisfying the following relationships: a + 2b + c + d = 4, 0</=a<3, 0<b<2, 0<c<4, and 0<d<4; (B) nonionic or anionic surface active agent; (C) photo-semiconductor; and (D) water. co
