Primer coating (Top) | It is helpful to strengthen the adhesion to the substrate so that the paint is not easy to desorb after the paint film is permeated, and it will also improve the corrosion resistance because the primer contains corrosion inhibitors, such as chromate pigments, which make the anode passivation. To improve corrosion resistance. |
Front coating | It shields sunlight and prevents ultraviolet rays from damaging the coating; when the primer coating (Top) reaches the specified thickness, it can form a dense shielding coating, reducing water and oxygen permeability. |
Primer coating (Back) | The effect is to prevent corrosion of steel plates from the inside. |
Zinc coating | Generally use galvanized or galvalume steel, this part of the product's service life has the greatest impact, the thicker the coating corrosion resistance performance is better. |
