A multi-layer coating system comprises (a) a base coating for coating a substrate, and (b) an antifouling coating composition adapted to be disposed over the base coating, the antifouling coating composition comprising a hydroxyl terminated polydimethylsiloxane, a curable polyether-containing silane of the Formula (1): (R1O)a(R1)(3-a)Si—R2—(Si(R1)2O)p—Si(R1)2—R2—O—(CH2—CHR1—O)q—R1  (1) where a is 1-3; R1 is H or alkyl radical from C1-C10; R2 is alkylene from C2-C10; p is 1-100; and q is 1-50. The base coating composition can comprise an epoxy modified adhesion promoter. A single layer coating composition comprises a compound of Formula (4): (R1O)a(R1)3-a—Si-M-(Si(R1)2O)r—(Si(R1)(O1/2)(O))t—(Si(X)(O1/2)(O))v—Si(R1)2-M-Si(OR1)a(R1)3-a  (4) where R1 is H or an alkyl radical M is R2 or oxygen; r is 0-1000; t is 1 to 20; v is 0 to 20; X is —R2—(N(R1)1-b(Y)b—R2)c—N(R1)2-b(Y)b; b is 0-2; c is 0-5; Y is R1 or an organic radical with an epoxide at one terminal; and R2 is an alkylene from C2-C10, with the proviso that at least one Y is an organic radical with an epoxide at one terminal. The respective compositions are such that the antifouling coating composition sufficiently adheres to the base coating composition without the need for a tie coat layer.

Abstract: The present invention provides curable compositions that are substantially free of metal catalysts including both tin and non-tin metal catalysts. The curable compositions employ a catalyst system comprising the combination of a carboxylic acid, an amino-containing adhesion promoter or a mixture of amine-containing adhesion promoters and an amino-containing siloxane. The combination of these materials accelerates the condensation curing of moisture curable silicones/non-silicones even in the absence of a metal-based catalyst.
