To evaluate media blasting for epoxy paint removal.
Date Run:
01/25/2002
Experiment Procedure:
Several precontaminated parts were cleaned between 5 and 10 minutes in the media blasting unit. The baking soda unit operated between 85-105 psi. After the parts were cleaned, a 5 second rinse was performed with a tap water spray at 70 F. Parts were wiped with a paper towel followed by a 1 minute heat gun drying cycle at 500 F. Parts were inspected using a microscope.
Trial Results:
Upon inspection under the microscope, parts cleaned with the baking soda appeared to be free of the epoxy paint. There was good removal on the rough surfaces. The thick coatings required substantial time for removal.
Success Rating:
A follow up test, usually based on company input.
Conclusion:
Baking soda was successful in removing the epoxy paint from the supplied parts.
