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:

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 lacquer face, lacquer further enhances the sealing of the coating and prevents the electrophoretic layer from failing due to mechanical damage or environmental erosion, especially it is suitable for high humidity or chemically contaminated environments.

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).

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.

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.
