Abstract:
A process for forming a multi-layer finish having an automotive quality appearance on a substrate selected from the group consisting of automotive bodies and automotive parts comprising the steps of:1) applying a coating layer selected from the group consisting of a primer coating layer and a primer surfacer coating layer comprising a film forming binder and pigments to a substrate and curing the layer at an elevated temperature; 2) applying a base lacquer coating layer onto the coating layer applied in step 1), wherein the base lacquer coating layer comprises a color-imparting layer and a binder selected from the group consisting of a binder curable exclusively by free radical polymerization, a binder curable exclusively by cationic polymerization and a mixture of binders one curable by free radical polymerization and a second curable by cationic polymerization; 3) curing the base lacquer coating layer with UV energy radiation; 4) applying a clear lacquer coating layer containing a binder over the base lacquer coating layer wherein the binder of the clear lacquer coating is selected from the group consisting of a binder curable exclusively by free radical polymerization, a binder curable exclusively by cationic polymerization and a mixture of binders curable by free radical polymerization and a second curable by cationic polymerization; and 5) curing the clear lacquer coating layer with UV energy radiation to from a finish having an automotive quality appearance.
