Description

Technical field [0001] The invention belongs to the technical field of coatings, and particularly relates to a primer composition for bicycles. Background technique [0002] The primer is the first layer of the paint system. It is used to improve the adhesion of the topcoat, increase the fullness of the topcoat, provide alkali resistance, and provide anti-corrosion functions. At the same time, it can ensure the uniform absorption of the topcoat, which is the best performance of the paint system. Good results. [0003] Traditional primers for bicycles are generally solvent-based primers, which contain a large amount of harmful solvents. These solvents will cause certain damage to the constructors and contacts during the construction and use process. Summary of the invention [0004] The technical problem solved by the present invention is to provide an environment-friendly primer composition for bicycles. [0005] In order to solve the above technical problems, the technical solution...
