Abstract:
The present invention relates to a process for repairing a coating film by applying an adhesion primer comprising a hydroxy-functional (meth)acrylate resin, a hydroxy-functional epoxy resin, a polyisocyanate, and an epoxy-functional organosilane directly to a substrate that is a substrate body with an original coating that has defects, to form an adhesion-promoting film and, applying at least one further layer of coating to the resultant adhesion-promoting film. The invention further relates to the use of the adhesion primer to improve the adherence of a further coating layer to such substrate, preferably to a substrate with a substrate body of glass fiber-reinforced unsaturated polyester resin, of glass fiber-reinforced epoxy resin, or of glass fiber-reinforced vinyl ester resin, wherein the further coating layer preferably is a polyurethane-based coating. The present invention further relates to a substrate coated with a coating film that has been repaired according to such a process.

Claim (Index 1):
A process for repairing a coating film comprising:\n (1) applying an adhesion primer directly to a substrate; (2) forming a polymer film from the applied adhesion primer to obtain an adhesion-promoting layer; (3) applying a further layer of coating composition to the adhesion-promoting layer; and subsequently (4) allowing the further layer of coating composition to cure to form a further coating layer, wherein the substrate is a substrate body with an original coating that has defects, wherein the adhesion primer comprises components (A) and (B), wherein component (A) is a binder component comprising:\n (A1) a hydroxy-functional (meth)acrylate resin; and \n (A2) a hydroxy-functional epoxy resin, \n and component (B) is a curing component comprising:\n (B1) a polyisocyanate; and \n (B2) an epoxy-functional organosilane.
