    Abstract: A coating composition suitable for providing a hardcoat comprising a topcoat and an epoxy modified adhesion promoter. The epoxy modified adhesion promoter comprises, in one embodiment, a molecule with the formula (1): U-Q-R1—SiR2gR3(3-g)   (1) wherein Q is —CH2CH(OH)CH2—O— or —CH2CH(OH)CH2—NR4—; U is: —O—(C6HhR2(4-h)—CR5—C6HhR2(4-b)—O—H2CH(OH)CH2—O)i—C6HhR2(4-h)—CR5—C6HhR2(4-h)—O-J; where R2 is chosen from a C1-C10 alkyl or a substituted or unsubstituted phenyl group; R3 is chosen from an alkoxy, an acetoxy, or a ketoxime radical; R1 is a C1-C4 alkylene; g is 0-2; h is 0-4; R4 is hydrogen or —CH2CH(OH)CH2—U—; R5 is hydrogen or an alkyl; i is 0-100; and J is H, Q-R1SiR2hR3(3-h), or formula (2). The coating composition is suitable for application to a substrate without the use of a primer.

    Abstract: A multi-layer or single layer antifouling coating system. 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.
