Common knowledge of metal pretreatment

Provides a clean surface for metals, significantly improves coating adhesion, and doubles coating corrosion resistance.

Practice has proved that although the same coating is used for metal coating, the corrosion resistance of the coating obtained after coating is also different due to different methods and quality of pre-coating treatment, and the effects are very different. Workpieces without pre-treatment or low-quality pre-painting treatment can only be a waste, even if they are coated with high-grade paint, and can not get good coatings and effects. Therefore, how manufacturers choose high-quality pre-coating agents is a very necessary and critical issue.
