Trial #1
To evaluate alternatives on second supplied contaminant
Nine products were selected based on client request for vapor degreasing solvents. Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate. Twenty-seven preweighed silver plated copper coupons were coated with the Houghton Chemical Cut-Max 135 (64742-52-5, 64741-96-4) using a hand held swab. Coupons were weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each solution for 5 minutes using stir-bar agitation. After cleaning parts were weighed a final time and efficiencies were calculated.
All nine products removed over 85% of the oil. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
