Trial Number 8

Trial Purpose:

To evaluate the efficiency of various heated drop in solvent replacement in removing Momentive Grease from Brass.

Date Run:

03/25/2016

Experiment Procedure:

Brass coupons were weighed to get their initial weights. The bottom third of each coupon was coated in the Momentive Grease. The coupons were re- weighed. The weights were recorded. The coupons were placed in the heated drop-in solvent replacement for 5 minutes. The coupons were removed out of the cleaning solution and placed to dry on a rack for 15 minutes. Then the final weights were taken and recorded.
