| Abstract: | Painting providers required decreasing the number of coating layers in order to reducing energy consumption and avoid surface defects caused by multi-coat process. To meet this market requirement, a single-coat, high-gloss black PU coating for various PC, PC/ABS substrates was developed ~with selected different resins, additives and solvents. The coating had outstanding performance and aesthetic effect. Then, the film performance was tested and all factors affecting coatings performance were analyzed. The results indicated： the coating had a stable adhesion and outstanding chemical resistance on PC substrate, could realize re-painting after complete curing and was especially suitable for painting automotive interior ornaments. |
