Foul preventing coating composition

摘要

The invention relates to a coating composition for use as a coating to prevent fouling in a marine environment, comprising: a) a curable polysiloxane polyoxyalkylene block copolymer; b) a catalyst of general formula (i) wherein each R1 is independently a monovalent hydrocarbon group, each R2 is independently selected from a hydrogen atom, a monovalent organic group, a siloxane group, or a silyl group of formula —SiR33, wherein each R3 is independently a monovalent hydrocarbon group, and n is an integer having a value of 0 or greater, and optionally: c) a filler and/or pigment.;
