Powder coating is a type of coating technique that is found and spread all over the world within past few decades. Powder coating process is done electrostatically by spraying dry powder to the mill finish product without using any catalyst, whereas liquid painting requires solvent or water as a catalyst. Moreover, unlike liquid painting, powder coating finish has no sagging mark.
These are advantages of using powder coating:
- Increase tensile and scratch resistance.
- Increase corrosion/weather resistance.
- Available in wide variety of colors.
- Environmentally friendly and virtually pollution free.
