What is Powder Coating?
Powder coating is a solid powdery synthetic resin coating composed of solid resin and pigments, fillers and additives. Unlike ordinary solvent-based paints and water-based paints, its dispersion medium is not solvent and water, but air. It has the characteristics of no solvent pollution, 100% film formation and low energy consumption.
Polyester Powder Coating
This series of products is based on polyester resin and is used for ordinary powder coatings indoors and outdoors.Available in a variety of colors, patterns and gloss. Can also be designed and manufactured according to customer requirements. Suitable for outdoor products such as home appliances, highway guardrails, general industry, automotive parts, outdoor furniture and construction machinery
