Trial Number 444

Trial Purpose:

removing cool tool II from the surfaces of aluminum by using non-toxic cleaners.

Date Run:

05/15/2008

Experiment Procedure:

products were based on the compatibility of substrate and removal of foreign substance. Used 5% concentration and heated the samples at 135F. The coupons were immersed in a product for 5 minutes, rinsed for 30 seconds in tap water at 120F and dried in 30 seconds.
