Which resin is better for glass paint?

When choosing resins for glass paints, factors such as the specific usage environment, performance requirements, and cost need to be comprehensively considered. For indoor decorative glass, acrylic resin is a suitable choice. For industrial or laboratory glass with high requirements for adhesion and mechanical properties, epoxy resin is more appropriate. In scenarios where both high decorative and comprehensive performance are required, polyurethane resin has its advantages.

The acrylic resin provided by Jiangmen Resin has good weather resistance. It can resist ultraviolet rays and the impact of wind and rain, and maintain the gloss and color stability of the paint surface for a long time. For example, when used in outdoor glass decoration, the appearance can still remain good after many years. It has strong adhesion. Due to the polar groups in its molecular structure, it can form chemical bonds or hydrogen bonds with the hydroxyl groups on the glass surface for firm adhesion. It dries quickly. It can dry rapidly at room temperature, and heating can further shorten the drying time. It also has good chemical stability and can tolerate common chemicals such as weak acids and weak alkalis.
