When selecting a primer, consider the adhesion properties. For top coating, prioritize corrosion resistance and color retention.
Standard painting thickness ranges from 18-22μm, with maximum top paint reaching 55μm. Thicker coatings generally offer better durability.
Selection should be based on usage environment. For example: Dx51d+AZ150 PVDF/HDP 30μm is suitable for marine or chemical factory applications.
Common base metals include:
Higher zinc content typically results in longer service life, with zinc coating ranging from AZ30g-AZ275g.
