Abstract
The quality of painted surfaces of polymer composites is improved by first forming an electroless metal coating on the molded surface of the composite and then electroplating a coating of zinc or zinc alloy on the metallized composite surface. The 'galvanized' composite surface provides a good base for electrostatic deposition of either liquid or powder paint and the zinc surface prevents the formation of defects in the painted surface during heating of the composite to dry or cure the paint film.
