Primer needs to have uniform and good adhesion with both, good leveling, no volatile substances, and certain heat resistance. For certain flexible substrates, the primer also needs to have sufficient flexibility. There are various types of primers available in the market, such as epoxy primer, fluorocarbon primer, and passivation primer. These primers each have their own characteristics, such as epoxy primer having excellent adhesion and corrosion resistance; Fluorocarbon primer has excellent weather resistance and UV resistance; The passivation primer is an environmentally friendly water-based coating that can effectively improve the adhesion and corrosion resistance of the electroplating layer.
