What is chemical pre-treatment?

For powder coating, optimal pre-treatment is the absolute basis for a quality product. Chemical pre-treatment involves using chemicals to condition the substrate. After this treatment, the product is ready for powder coating. Each substrate receives a different pre-treatment. Chemical pre-treatment is done in three phases:

1. Cleaning and degreasing
2. Pickling
3. Application of the conversion layer
The conversion layer ensures good adhesion of the powder coating and prevents corrosion.
