1. For asphalt coating, preheating the drawing parts before painting can improve the adhesion of asphalt paint and accelerate drying.
2. The cement mortar lining with special coating can improve the corrosion resistance of the lining of the stamping tensile parts.
3. Coal tar epoxy coating is a two-component coating with high adhesion and smooth surface.
4. Epoxy ceramic lining is a kind of anti-corrosion coating for stamping parts because of its difficult manufacturing process and high cost, so it has certain limitations in use and has high adhesion and finish.
5. Aluminate cement coating or sulfate cement coating, these two kinds of special cement coating are suitable for internal corrosion protection of stamping tensile parts and improve the ability of corrosion resistance.
6. Polyurethane coating is a new green special coating developed to meet the needs of environmental protection. It has good wear resistance and corrosion resistance.
