Physical properties of electrophoretic racks of engraved round metal logo-A

The physical properties of ‘Engraved Round Metal Logo’ need to be analysed in conjunction with the characteristics of the electrophoretic coating and the frame (transparent protective lacquer), and the following are the key performance indicators and technical explanations:

1. Corrosion resistance
   Advantage of electrophoretic coating: Electrophoresis process forms a uniform and dense resin film on the metal surface through electrodeposition, which effectively isolates water, oxygen and corrosive media. For metal Logo, it can significantly improve the resistance to salt spray, acid and alkali, and prolong the outdoor service life.
   Role of lacquer (clear lacquer): As a topcoat, lacquer further enhances the sealing of the coating and prevents the electrophoretic layer from failing due to mechanical damage or environmental erosion, especially suitable for high humidity or chemically contaminated environments.
2. Hardness and abrasion resistance
   Characteristics of electrophoretic layer: The hardness of electrophoretic coating is usually 2H-3H (pencil hardness), which can resist slight scratching, but need to avoid direct scratching by sharp objects.
   Enhancement effect of lattice frame: Transparent lattice frame has higher hardness after curing (e.g. 3H-4H), which forms a protective barrier and reduces the abrasion of the Logo surface, especially suitable for high-frequency contact areas (e.g. electronic product housings).
3. Adhesion
   Advantage of electrophoresis process: Electrophoresis coating combines with metal substrate through electrochemical action, with strong adhesion (usually ≥5B, 100-g test), and can withstand mechanical stresses such as bending and impact.
   Compatibility of lattice frame: High-quality lattice frame has good compatibility with electrophoresis layer and forms a composite coating after curing, which further improves the overall adhesion and avoids delamination or peeling off.
4. Appearance and gloss
   Electrophoretic coating effect: It can provide various surface effects such as high-gloss, matte, etc., with even colour and no flow marks or orange peel phenomenon.
   Modifying effect of lacquer frame: Transparent lacquer frame can enhance the gloss level (e.g. from semi-gloss to high-gloss), and at the same time protect the colour stability of the electrophoretic layer to prevent fading or yellowing caused by UV rays.
