Abstract

With the increasing concern for both personal and environmental safety in plating operations handling hexavalent chromium, a new process which prepares plastics without this hazardous material would be advantageous. This paper outlines new advances in pretreatment, chemical metal deposition and electrolytic metal deposition of commercial grade resins of interest to decorative plastic platers. The requirements and results of adhesion testing, thermal cycle performance and appearance of part finish will be discussed and demonstrated. Coupled with various trivalent chromium final finishes a decorative process line which is completely free of hexavalent chromium is possible.
