This paper describes a research on adhesion mechanism of plastic plating using PP resin as the base material. It is considered that since PP resin is a high crystalline polymer, its crystalline morphology is different depending on cooling methods. The influence of cooling methods on the adhesion strength, was determined at first. However, it appears that the adhesion strength was also influenced by other factors, then, it was also examined how the adhesion strength was affected by the kinds of pre-etching solvents, the wettability of etched resin, the NaHSO3, treatment or the time of ageing. The results of the experiments were summarized as follows: 1) The amount of carbonyl radical generated as a result of etching was proportional to the etching temperature and time. 2) Crystalline fraction of PP resin when molded became large with cooling time. 3) Crystalline fraction by etching increased with the etching time. 4) The test pieces prepared by cooling in the air were larger in their adhesion strength than those of rapid cooling. 5) Organic solvents used in pre-etching caused some effects on the adhesion strength. 6) Adhesion strength and wettability held good, but the influence of which wettability exerts on adhesion strength was smaller than that of surface shape. 7) Cr6+, adsorbed on PP resin, as a result of etching with chromic acid, has an effect on adhesion. 8) Increase of adhesion strength, after ageing, might be attributed to the chemical change in interface.
