What exactly is the distinction between PVDF and powder coating?

Spray coating is a critical step in the production of aluminum wall panels (aluminum cladding). Electrostatic spraying makes use of electrostatic spray guns. Electrostatic spraying is classified into two types: electrostatic liquid spray coating (also known as PVDF) and electrostatic powder coating (powder coating). Spraying procedures vary widely depending on the spraying object and the desired effect. Each one has unique qualities. Here is Pvdf Coating Aluminum Solid Panel.

DIFFERENCES

1.Various paint materials

PVDF spray painting makes use of finely adjusted (modulated) paint, which is a fluid, whereas powder coating makes use of a powdered solid.

2.Various spraying locations

Powder spraying is done primarily in a powder spraying chamber, while PVDF spray coating is done primarily in a paint booth.

3.Different ways of working

PVDF spray coatings can be applied using a plunger pump or a diaphragm pump, which applies pressure and static electricity for spraying. The electrostatic powder is sprayed on the gun mouth, and the coating is applied by shaking or inhaling.

4.Various drying techniques

PVDF can be dried using natural leveling drying or baking. Baking is the main method used to dry powder coatings.

5.Various spraying outcomes

The PVDF coating film is very thin following natural leveling drying. The powder coating performs well in terms of anti-corrosion, high adhesion, and thick coating film, but it can fade its color over time when exposed to sunlight outside.

Normally, we advise using PVDF coating for exterior applications, especially in areas with intense sunlight or humid environments like the seashore. Additionally, powder coating can be used to decorate interiors.

6.Various prices

The cost of powder is typically $10 less than paint for the same brand.

SIMILARITY

Before spraying, the same treatment is applied.

Anti-oxidation and chromate treatments, which aim to remove oil, dust, and rust from the aluminum plate surface, make up the majority of the pre-treatment used in the process. The treatments not only stop rust but also make the paint film more adherent.

SUMMARY

High efficiency, energy efficiency, reduced pollution, environmental protection, high paint utilization, and good coating performance are all benefits of powder coating. Its lack of sunlight resistance is a drawback.

High brightness, thin coating, stable color, strong weather resistance, and resistance to easy fading and discoloration are all benefits of PVDF spray coating.

Various spray coating techniques must be chosen based on the particular products and needs. Powder coating can be used to create special effects like different wood grain or stone patterns in the context of aluminum wall panels.
