Rub, Rub, Rub.......What is this so-called "Rub test"?


I'm still in desperate need on information regarding "rub" testing of powdercoat samples. I have checked the ASTM website, but no luck.... Does anyone have ANY information related to this? Thanks, Andrew

I am not sure why you are having trouble finding information on the solvent rub test. Contact us.

You can get a test kit and instructions from any powder paint company. The test is used as a rough indication of cure on coated parts.

DO NOT try to draw conclusions from the test results without knowing what a successful panel looks like. Different powders respond differently to the MEK / methyl ethyl ketone solvent in the test, and you'll have to compare results to a known good panel.

If you have trouble getting a test kit let me know, I can set you up.

The Powder Coating Institute has several Standards for powder coating and the MEK Cure test is one of them. It is on the Hand Book for Finisher's recommended procedure #8 or you can reach The Institute [at 2121 Eisenhower Avenue / Suite 401 / Alexandria, VA 22314].

Good Luck!
