What is a 3-in-1 chemical in powder coating?
- In powder coating, a 3-in-1 chemical refers to a single chemical treatment that combines three essential surface preparation steps:
- 3-in-1 = Degreasing + Derusting + Phosphating
It simplifies the traditional multi-stage pretreatment process by performing:
Degreasing – Removes oils, greases, and other organic contaminants.
Derusting – Removes rust and oxides from the metal surface.
Phosphating – Deposits a phosphate layer that improves paint adhesion and corrosion resistance. #3-in-1 chemical Manufacturer.
