Development of epoxy primer for color coated board
With the rapid development of the color-coated board industry, it has become a hot spot for domestic and foreign research to develop high-performance color plate coatings to meet the needs of advanced products and diversification.
With the rapid development of the color-coated board industry, it has become a hot spot for domestic and foreign research to develop high-performance color plate coatings to meet the needs of advanced products and diversification. It is essential to formulate a primer with good adhesion and flexibility, as well as a good compatibility with the topcoat, to improve the performance of the color coating. However, due to the variety and quality of domestic coil coatings lags behind foreign products, China's producers have to use high-priced imported coatings when producing color plates, which greatly affects the development of China's color plate industry [1 ~ 2]. The formulation of the primer is a complicated process due to many influencing factors. In this paper, the orthogonal experiment method is used to determine the influence of various factors on the performance of epoxy primer, so that the optimal formula can be reasonably determined with fewer steps, and the obtained film has the advantages of obvious hardness and solvent resistance, and adhesion. The performance is also excellent.
