Patent ID: 8067066

Claim:
A method of coating a substrate, for establishing a fouling-release coating system the method comprising: (A) applying a first coating composition to at least a part of the surface of said substrate thereby establishing a tie-coat on said substrate, wherein said first coating composition comprises (i) 0-60% by wet weight of pigments and fillers; and (ii) the balance of a binder phase comprising: 1-90% by wet weight of one or more amino-functional compounds, 1-90% by wet weight of one or more epoxy-functional compounds, and one or more adhesion promoting agents selected from the group consisting of hydroxy-functional polysiloxanes, hydroxyalkyl-functional polysiloxanes and C 1-4 -alkoxy-functional polysiloxanes; and at least one member selected from the group consisting of (a) amino-functional polysiloxanes; and (b) epoxy-functional polysiloxanes; and wherein said one or more adhesion promoting agents are present in an amount of up to 20% by wet weight, and (B) applying a second coating composition onto said tie-coat thereby establishing a fouling release coating on said substrate.
