One of the ways to protect metal products from corrosion is to apply a protective layer of paint or primer to their surface. There are a lot of technologies for carrying out this procedure, ranging from the use of a hand roller and ending with automated painting lines. But one of them deserves special attention - the so-called powder painting of metal , which is increasingly popular due to a whole list of advantages.
Principle of paint application
The schematic diagram of powder painting is to use the electrostatic properties of substances dissimilar in their structure. Special coloring fine powder, which includes:
- Polymer resins.
- Chemical hardeners.
- Color fillers.
In the painting chamber, it is sprayed in the form of a concentrated air suspension on the surface of a metal product (part) and is held on it due to the potential difference. After processing in a thermal chamber, the applied layer is melted and creates a single, airtight film.
After such processing, the surface to be painted can acquire a wide variety of styles through the use of a wide range of colors and shades. This method does not cost more than the options for staining with ordinary paint, but it has a high quality of the final result.
The main difference between conventional liquid paint and powder coating is that powder coating does not require a solvent to hold the binder and filler parts in the coating, and then forms a durable shell when exposed to heat. Powder paint can be thermoplastic or thermosetting resin. It is used to create a hard coating that is far superior in strength to conventional paints. Powder coating is mainly used for metal products ,
You can get more detailed information about the possibilities of powder coating, as well as familiarize yourself with the online catalog of colors of its execution, using the official website of SMK Company, which specializes in the mass production of metal products and provides this type of service using its own high-tech equipment in Samara.
