Electroless plating of moisture-curable polyurethane undercoating films

The compatibility of using moisture-curable polyurethane (MCPU) system as a thin undercoating layer with electroless plating process was evaluated. The characteristics of the MCPU before and after chemical etching treatment were analyzed using atomic force microscope (AFM), scanning electrode micros...
