Thermosetting powder coating

Thermosetting powder coating is a new type of environmental protection coating, which is composed of resin, pigment and additives. After baking at high temperature, a hard, smooth, wear-resistant and corrosion-resistant coating is formed. Compared with traditional coatings, thermosetting powder coatings have the advantages of no solvent, no volatile organic compounds, no pollution and easy automatic spraying, and are widely used in surface coating of various metal products.

Characteristics of thermosetting powder coatings

1. environmental protection: thermosetting powder coating does not contain solvents and volatile organic compounds, and will not pollute the environment.

2. Strong wear resistance: the coating formed by thermosetting powder coating has high hardness, strong wear resistance and is not easy to scratch.

3. Good corrosion resistance: Thermosetting powder coating has good corrosion resistance and can keep the integrity of the coating for a long time in harsh environment.

4. Rich colors: Thermosetting powder coatings are bright and colorful, which can meet the needs of different customers.

5. Easy automatic spraying: the automatic spraying equipment for thermosetting powder coatings is simple to operate and has high production efficiency.

Application of thermosetting powder coatings

Thermosetting powder coatings are widely used in the surface coating of metal products, such as furniture, building materials, automobiles and electrical appliances. Among them, the furniture industry is the main application field of thermosetting powder coatings. The wear resistance and corrosion resistance of thermosetting powder coatings are very suitable for the surface coating of furniture, and they are rich in color and elegant in appearance, which can meet the needs of different customers.

Operation steps of thermosetting powder coatings

1. Preparation: carry out surface treatment on the metal products to be painted, including degreasing, rust removal and phosphating.

2. Spraying: the thermosetting powder coating is poured into automatic spraying equipment for spraying. Attention should be paid to the thickness and uniformity of spraying to ensure the coating quality.

3. Curing: sending the sprayed metal products into an oven for curing. The curing temperature and time need to be adjusted according to the type and thickness of thermosetting powder coatings to ensure the quality of coatings.

4. Inspection: the cured metal products are inspected, including the thickness, hardness, wear resistance, corrosion resistance and other indicators of the coating.

Development trend of thermosetting powder coatings

With the improvement of environmental awareness, thermosetting powder coatings will be more widely used. At the same time, the technology of thermosetting powder coatings is also developing, and the types and properties of coatings are also improving. In the future, thermosetting powder coatings will be more environmentally friendly, durable and beautiful, and become the mainstream coatings for surface coating of metal products.
