The metal surface has a negative charge to interact with cations, which increases adhesion and can also passivate the metal surface. In addition, there is a good binding force between the cationic primer and the anionic topcoat, which improves the comprehensive performance of the composite coating; however, at present, domestic and foreign research on cationic acrylate emulsions in metal antirust primers is far from enough. . Cationic structural groups also have a sterilizing function. The higher the cation content, the better the sterilizing effect of the emulsion after film formation. Therefore, the cationic acrylate emulsion is also suitable for related coatings with antibacterial and sterilizing requirements.
