SIMPLIFIED PRETREATMENT FOR POWDER COATING

Dear Mr. Panchal,
If you are using the seven stage pretreatment, we presume you are using zinc phosphating. Now, if your component contains rust, then this method is necessary.
In case the components are without rust, and the customer does not have a requirement for zinc phosphating, then there are single stage, no-rinse single tank pretreatments in the US and Europe which can do pretreatment in one stage.
However, they have not taken off well in India, primarily due to rust problem.

Where can I find out more about these one step pretreatments that are used in Europe for rust free mild steel?

Hi, Jerry. All of the manufacturers of pretreatment chemicals, like Chemetall, have one-step pretreatments in their repertoire.
