Powder coating is a solid powder synthetic resin coating composed of solid resin, pigments, fillers, and additives.

Unlike ordinary solvent based coatings and water-based coatings, its dispersion medium is not solvent and water, but air. It has the characteristics of solvent-free pollution, 100% film formation, and low energy consumption.

Powder coatings are divided into two categories: thermoplastic and thermosetting. The appearance (gloss and leveling) of thermoplastic powder coatings is poor, and their adhesion to metals is also poor. Therefore, they are rarely used in the field of automotive painting. Thermosetting powder coatings are generally used in automotive painting, which use thermosetting synthetic resins as film-forming substances. During the drying process, the resin first melts, and then chemically crosslinks and solidifies into a flat and hard coating film. The appearance, various mechanical properties, and corrosion resistance of the paint film formed by this coating can meet the requirements of automotive painting.

Advantage:

1. This product does not contain toxicity, solvents, or volatile toxic substances, so there is no poisoning, no fire, and no; Three wastes” The issue of emissions and other public hazards fully complies with the requirements of the national environmental protection law.

2. The utilization rate of raw materials is high. Some well-known brand powder suppliers produce powders whose overspray can be recycled, and the highest utilization rate can even reach over 99%.

3. After pre-treatment of the coated material, it can be applied in one go without the need for a primer to obtain a sufficiently thick coating film, which is easy to achieve automated operation, has high production efficiency, and can reduce costs.

4. The coating is dense, with good adhesion, impact strength, and toughness, high coverage of edges and corners, and excellent chemical corrosion resistance and electrical insulation performance.

5. Powder coating storage, transportation safety and convenience.
