Zhou Chunli, Li Yang, Feng Chunmiao, and Wu Kuilu from Zhonghai Changzhou Paint Chemical Research Institute Co., Ltd. used RDS scraping rods to prepare PET film polyester topcoats in this article, and studied their properties in depth. It is coated with RDS No. 3# scraping bar on the spangle-free hot-dip galvanized steel sheet of a specific size, and then uses RDS20#, 24#, 28# and 32# scraping bars to coat self-made topcoats of different thicknesses to obtain Dry film of specific thickness, laminate the PET film to the surface of the topcoat while it is hot, cool down, and test the performance of the composite coating.
