Water-based Red Oxide Primer

Q. Using water-based red oxide primer in conventional spray application, we find it extremely difficult to clean equipment afterwards. Obviously spills and overspray/contamination of equipment occurs during operation. These cannot be cleaned immediately while spraying. Even Acetone does not dissolve this primer satisfactorily. Any suggestions for cleaning equipment after spraying?

Many thanks!

A. Unfortunately, I can't assist you because you only told me that you use a red oxide primer. You didn't tell me more about the type of resin system the coating comprises; alkyd, acrylic, epoxy, polyurethane, solvent-based or waterborne. The datasheet that comes wirth the paint should tell you what to use to cleanup your equipment.

You should be able to call your paint supplier and ask for this information.

Good luck,

Ron Joseph
