摘要

Application parameters: flow rate, target distance, film thickness, and dehydration oven temperature were investigated in relation to automotive waterborne basecoat popping. The study was conducted in three phases using melamine cross-linked acrylic latex basecoat and acrylic acid/epoxy clear coat. All experiments were conducted at the Automotive Research and Development Centre in Windsor, Ontario, Canada. First, a relationship among tip speed, flow rate, and film thickness was established, which was used later to set constant film thickness. The Phase-1 study indicates that flow rate and target distance are not significant in relation to popping. A complementary analysis indicates that film thickness significantly affects popping. Film thickness was also found significant in relation to popping from the Phase-2 study. The Phase-3 study indicates that dehydration oven temperature and film thickness significantly affects popping. Although this study identified the factors causing waterborne basecoat popping, conditions for a pop-free paint surface were not achieved.
