ANTIFOULING SILICONE EMULSION COATING COMPOSITION,A PROCESS FOR PRODUCING THE SAME, AND AN ARTICLE COATED WITH THE SAME

摘要

The present invention is directed to an antifouling silicone emulsion coating composition comprising the following components (A), (B), (C) and (D). The amount of component (C) incorporated in the composition being in the range of 5 to 80 % by weight relative to the total solid contents in the composition. The components are defined as follows: (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): R2aSiOb (OR1)c(OH)d wherein R1 and R2 represent a monovalent hydrocarbon group; a, b, c and d are numerals satisfying the following relationships: a + 2b + c + d = 4, 0.ltoreq.a<3, 0
