In the industry, surface treatment before painting is a crucial step that determines the quality of the coating, corrosion resistance, and product lifespan. A proper pretreatment process is essential.
This not only helps increase paint adhesion but also improves production efficiency, reduces maintenance costs, and meets international standards for steel.
AD Chemicals offers a complete portfolio of chemicals for the industry, from traditional iron phosphate products to advanced alternatives with advanced features.
Our solutions are designed to enhance the performance of steel products in various applications.
- Iron phosphate
- One-step preprocessing
- Passivation of Cr³⁺
- Polymer/Silane Technology
- Does not contain Cr(VI)
- Meets QUALISTEELCOAT standards
Why is surface treatment necessary for steel before painting?
After machining, surfaces often contain grease, dirt, oxide layers, and other impurities. If not properly treated, the paint layer can peel off, reducing corrosion resistance and shortening the product’s lifespan.
An effective surface treatment process helps to:
- Increases the adhesion of the paint layer.
- Improved corrosion resistance.
- Increase the durability of the paint system.
- Improve product quality.
- Reduce maintenance and repair costs .
