What are the ways to deal with anti-corrosion in sheet metal processing

1. Derusting the bottom layer of sheet metal processing products

2. For sheet metal processing products, epoxy zinc-rich primer is mainly used for anti-rust primer of steel structure and steel products. Its coating film has excellent physical and chemical functions, easy to construct, and good supporting functions. The main ingredients are: epoxy resin, epoxy curing agent, zinc powder, anti-rust pigment, additives and organic solvents.

3. Epoxy mica center paint for sheet metal processing products: used in conjunction with epoxy zinc-rich primer, as a long-lasting anti-corrosion coating transition layer, its function is to enhance the sealing and anti-corrosion properties of the composite coating, and it can also be used As an anticorrosive and antirust primer, the coating film is strong, has excellent adhesion and sealing, and has excellent compatibility with the front and rear coatings. Its ingredients are: epoxy resin and curing agent, mica iron oxide and anti-rust pigments.

4. The surface layer of sheet metal processing products. The surface layer can be used for epoxy asphalt topcoat, chlorinated rubber topcoat, acrylic and polyurethane topcoat, fluorocarbon topcoat, etc.
