There are significant differences in function and purpose between topcoats and primers. The primer is mainly used as the basis of the topcoat to enhance the adhesion and decorative effect of the topcoat, while the topcoat is mainly responsible for decoration and protection, and has anti-aging, anti-scratch and other functions. The primer needs to be applied directly on the surface of the object as a solid foundation for the topcoat, enhances the adhesion of the topcoat, and improves the decorativeness of the topcoat. The topcoat is on top of the primer and is mainly responsible for decoration and protection, and has anti-aging, anti-scratch and other functions.
Basecoats and topcoats also differ in composition. Basecoats usually consist of film-forming substances, fillers, solvents and additives, while topcoats may contain clear topcoats and color concentrates. In terms of price, primers and topcoats vary depending on their use and ingredients, but in general there is a wide range of prices, and the specific choice depends on the quality of decoration required.
