Features in Each Work Process
1. Pretreatment and Electrodeposition
In the pretreatment process, the entire body is degreased, cleaned, and coated with zinc phosphate by dipping after being. After
the body has been cleaned with pure water, it is placed in an electrolytic bath of soluble primer (Cationic Electrodeposition). This
produces a thorough corrosion inhibiting coating on the inner surfaces and corners of the body, pillars, sills panel joints.
Chipping primer is then applied to the most susceptible area (see page
)
2. intermediate coat 1
The intermediate coat 1 is applied to the prepared surface in for further protection against damages.
