Aluminium panel painting process
The aluminum panels is made of high-strength alloy aluminum plate as the base material, which be formed by pretreatment and then sprayed with fluorocarbon.
Fluorocarbon topcoat has excellent corrosion resistance and weather resistance, can resist acid rain, salt spray and various air pollutants, has excellent cold and heat resistance, can resist strong ultraviolet radiation, and can maintain long-term color and no chalking , long lasting.

Aluminum Veneer Case
Excellent performance of fluorocarbon(PVDF) aluminum panels coating
1. The surface coating of PVDF aluminum panels has excellent weather resistance and UV resistance, the color is durable-stable and not easy to fade.
2. High acid and alkali resistance, can withstand the wind and sun in harsh environments.
3. Good adhesion, high toughness, strong impact resistance, strong pollution resistance, smooth coating, and easy to clean.
4. Widely color, bright and beautiful, good texture.there are solid paint and metallic paint, which can fulfill different requirements of customers.

Advantages of powder coated aluminium veneer
- Compared with steel plates and other plates, it has good durability, corrosion resistance and longer service life;
- It has good heat resistance and is not easy to change color at high temperatures;
- Has good heat reflectivity;
- It has good cost performance, durability and competitive price.
The aluminum panels highlights the modern life concept, embodies a high-end and luxurious architectural style, and relieves the pressure of urbanites. Many places like cafes and leisure clubs use aluminum panels.
Aluminum panels is moderately priced, durable, moisture-proof and waterproof, and has high plasticity. It has become the darling of many designers for decoration design in various places.
The edges of the board should be cut neatly without burrs or cracks. No open welding is allowed on the plate. The appearance should be neat and tidy, the pattern should be clear, the color should be basically the same, and there should be no obvious scratches. The decorative surface shall not have obvious indentation, imprints, bumps and other remnants. No obvious color difference, AE is not greater than 2.0 in arbitration.
