Apparatus and Method of Improved Performance of Hot Stamped Foil

A composite component includes a plastic substrate and a transfer foil adhered thereto. The plastic substrate and the foil are proud and define a peripheral edge with a tight outer radius. A thin first coating layer, such as a base coat or primer layer, is applied over the plastic substrate and foil and adheres the both the plastic substrate and foil. A thicker second coating layer, such as a clear coat, is applied over the first coating layer and adheres to the first coating layer. The first coating layer has a lower viscosity than the second coating layer. The second coating layer is more ductile than the first coating layer. The first coating layer acts a primer layer for applying the second coating layer. The second coating layer therefore protects the substrate and transfer foil and can withstand thermal shock and water immersion.
