To evaluate drop-in solvents on second supplied contaminant mix.
Date Run:
08/26/2004
Experiment Procedure:
Eleven products were selected from the previous test results. Each product was used at full strength in 250 ml beakers at room temperature.
Thirty-three preweighed CDA260 Brass coupons were coated with the second supplied buffing/milling compound mix using a hand held swab. Coupons were allowed to sit overnight and weighed a second time to determine the amount of soil added to each coupon. Three coupons were cleaned in each product for 5 minutes with no agitation. Coupons were air dried at room temperature. Once coupons were dry, final weights were recorded and efficiencies were calculated.
Trial Results:
All but one product (Vertrel MCA) removed over 80% of the contaminant within 5 minutes using immersion with no agitation. One product, Metalnox M6960 removed just over 90%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
