Unlike wet paint, powder coating provides a higher uniformity of colour and thickness consistency. Powder coated castings are cured at high temperatures to ensure tougher, more resilient finishes.
Castings with minor surface flaws may benefit from a powder-coated surface, which can help to conceal and hide cosmetic defects. Powder coating is predominantly used as a decorative cover for castings that require a coloured or high gloss exterior. However, powder coating can also be used to increase the durability of a casting due to its hardened, scratch and corrosion resistant capabilities.
- The powder and casting to be coated are oppositely electrostatically charged, making them attracted to each other.
- The desired dry powder is controllably sprayed at the casting surface.
- The powder sticks to the surface of the casting (including hard to reach areas) in a very even layer.
- The casting is then placed into an oven to cure.
Benefits of Powder Coating:
- Powder coating is a more environmentally friendly process because the powder contains no solvents, liquid or volatile organic compounds (VOC’s).
- Specialist powders are available for particular applications, including anti-bacterial coatings for medical applications
- Provides a decorative finish
- Increases the hardness of castings
- Provides castings with a scratch and corrosion resistant coating
- Can conceal minor surface flaws
- Unlike wet paint, the powder coating is not wasted on overspray and extraction making it a more effective painting process.
