What is powder coating?
Powder coating is a relatively new, but advanced finishing technology for a wide variety of metal surfaces. During the process, the product is chemically treated and covered with powder coating, which polymerizes in the oven. The powder-coated product is protected against heat, cold, scratching, corrosion, fading and other conditions and impact.
Powder paint coated surface is extremely durable and resistant. The paint retains its elasticity even in the event of deformation of the surface and is resistant to abrasion as well as other environmental impact.
Powder coating is available in a very wide variety of colors, textures, and luster. It also resists chemicals and is easy to maintain.
Main advantages of powder coating
- Reliable protection from corrosion.
- Nature-friendliness, no toxic substances.
- Multiple colours and a variety of textures.
- Resistance to impact: cracking, scratching, and colour fading.
- Suitability for surfaces of various metals: steel, galvanized metal, aluminum, brass, copper, bronze, titanium, lead, etc.
- The uniformity of the paint film.
The powder coating process
The work-piece is initially cleaned by removing rust and other impurities. The cleaning is followed by chemical treatment. Once chemically processed, the product is dried in the oven at temperatures not lower than 80-100 ° C. The dried work-piece is ready for painting. Electrically charged powder paint is sprayed on the grounded metal surface. This way, the piece is covered with paint evenly.
The coated product is placed in the oven where, at a temperature of 180-200 ° C, the paint polymerizes, that is, it melts on the surface of the product.
As the product cools, the coating hardens, thereby forming high-quality paint. Thus painted, the work-piece not only looks great but also has impeccable anti-corrosion properties and resists environmental conditions.
