RAL1014 ivory color pure polyester TGIC powder coating sprayed by electrostatic spray gun
Powder coating is a type of coating that is applied as a free-flowing, dry powder. The coating is typically applied electrostatically and is then cured under heat to allow it to flow and form a "skin".
The powder may be a thermoplastic or a thermoset polymer. It is usually used to create a hard finish that is tougher than conventional paint.
Polyester powder coating can be categorized into two groups: with TGIC or without TGIC. It can produce the product of high gloss (above 80 percent), sub-gloss (20-50 percent), and the matt. The gloss can also be adjusted according to the client's instruction.
Application
Powder coating is mainly used for coating of metals, such as household appliances, aluminum extrusions, drum hardware, and automobile and bicycle parts. Newer technologies allow other materials, such as MDF (medium-density fibreboard), to be powder coated using different methods.
