A Direct Plate Process for ABS and ABS/PC without use of Pd Catalyst or High Chrome Etch

摘要

This paper outlines the process sequence and performance tests for decorative plated plastics, which have been plated using a new process containing no palladium and very low concentration of Cr VI salts. The function and influence of each process step on the final performance requirements of adhesion and appearance of the plated parts will be discussed. Surface analytical and morphological changes in the surface will also be examined as function of process conditions in an attempt to better understand the mechanism of surface reaction and adhesion with the new process. The benefits of such a process are significant for cost, environmental, and productivity reasons in decorative plating of ABS and ABS/PC blends.
