A TIE-COAT COMPOSITION COMPRISING AT LEAST TWO TYPES OF FUNTIONAL POLYSILOXANE COMPOUND AND A METHOD FOR USING THE SAME FOR ESTABLISHING A COATING ON A SUBSTRATE

摘要

The present invention relates to tie-coat compositions for fouling- release paint systems. The invention provides a method of coating a substrate with a coating composition comprising at least two types of functional polysiloxane compounds selected from epoxy-functional polysiloxanes, amino-functional polysiloxanes, and particular adhesion promoting agents of the polysiloxane type. The present invention also provides a substrate coated with such a composition and a composition particularly useful for said method. The binder phase may also comprise constituents of epoxy paint compositions, e.g. epoxy resins and amine curing agents. The compositions are particularly relevant in combination with diorganopolysiloxane-based fouling-release coatings and anticorrosive epoxy primer coatings.
