Abstract

There are waterborne topcoat defects on rail vehicles such as dust particle,cratering,orange skin,fat edge,cratering,swelling and bubbling.The coating defects were effectively improved from the aspects of control of environment,the optimizations of process parameters and process methods,preventive and control measures.

Key words

waterborne topcoat;coating defects;process optimizations;control measures
