Pretreatment (degreasing/zinc phosphate)
Immediately after pretreatment, which is essential for increasing paint adhesion and improving rust prevention and corrosion resistance, foreign substances such as processing oil, rust prevention oil, dust, and fine metal pieces adhere to the workpiece surface.
For example, oil repels surface treatment chemicals, so complete painting is impossible if black scales or foreign matter remain. Pretreatment is the process to remove these substances.
There are two methods: ``degreasing cleaning'' to remove dirt and sebum from the metal, and ``zinc phosphate treatment'' which covers the metal with a special film that makes it adhere to the paint and makes it difficult to peel off, greatly improving corrosion resistance and adhesion. there is. We select the most suitable treatment method depending on the material and purpose, and guarantee a beautiful surface finish.
