Full pretreatment process

Question

Accepted Answer

The full pretreatment process involves cleaning, rinsing, and chemical treatment of the surface to prepare it for powder coating.

The surface is first cleaned to remove any dirt, oil, or grease using a degreaser or alkaline cleaner.
Next, the surface is rinsed with water to remove any remaining cleaning solution.
The surface is then chemically treated to improve adhesion and corrosion resistance. This can involve a phosphate or chromate conversion coating.
After the chemical treatment, the surface is rinsed again to remove any remaining chemicals.
The surface is then dried thoroughly before powder coating is applied.
