What are the characteristics of powder coating？

The coating is made of special resin, pigments and fillers, curing agents and other additives, mixed in a certain proportion, and then prepared by processes such as hot extrusion, crushing and sieving. They are stable in storage at room temperature. After electrostatic spraying, friction spraying (thermosetting method) or fluidized bed dip coating (thermoplastic method), they are heated and baked to melt and solidify to form a smooth and bright permanent coating film to achieve decoration. And the purpose of anti-corrosion.

Its characteristics are:
1. The product is non-toxic, free of solvents, and free of volatile and toxic substances, so there is no pollution, no fire, no discharge of "three wastes" and other public hazards, and it fully meets the requirements of the national environmental protection law.
2. The utilization rate of raw materials is high. The oversprayed powder produced by some well-known brand powder suppliers can be recycled, and the highest utilization rate can even reach more than 99%.
3. After the pre-treatment of the coated object, one-time construction, without the need for primer, can obtain a coating film of sufficient thickness, easy to realize automatic operation, high production efficiency, and can reduce costs.
4. Dense coating, good adhesion, impact resistance and toughness, high corner coverage, excellent chemical resistance and electrical insulation.
5. The storage and transportation of powder coatings are safe and convenient.

Compared with the traditional paint process, the advantages of powder coating are:
1. High efficiency: because it is a one-time film formation, it can increase productivity by 30-40% 2. Energy saving: reduce energy consumption by about 30%
3. Less pollution: no organic solvent volatilization (no harmful gases such as toluene and xylene in paint).
4. High paint utilization rate: up to 95% or more, and the powder can be used multiple times after recycling.
5. Good film performance: The film thickness can reach 50-80μm at one time, and its adhesion, corrosion resistance and other comprehensive indicators are better than the paint process.
6. High yield: before curing, it can be re-sprayed twice. There are many types of powder coating processes, and the common ones are electrostatic spraying and dipping.
Powder coating is a new type of solvent-free 100% solid powder coating. It has the characteristics of no solvent, no pollution, energy and resource saving, reduced labor intensity and high mechanical strength of the coating film.
It has three categories: thermoplastic powder coatings (PE), thermosetting powder coatings, and architectural powder coatings.
