Trial Purpose:
Laboratory evaluations of alternative cleaning products
Date Run:
05/27/2004Experiment Procedure:
Basic cleaning performance testing was conducted using ASTM G122 as the bases for cleaning.
Each product was used at full strength in a 250 ml beaker and heated to 96 F on a hot plate. Nine preweighed silver plated copper coupons were coated with the Houghton Chemical Cut-Max 135 (64742-52-5, 64741-96-4) using a handheld 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.
Trial Results:
| Cleaner | Initial wt | Final wt | % Removed |
| Vertrel MCA | 0.10830 | 0.0086 | 92.06 |
| 0.15790 | 0.0062 | 96.07 | |
| 0.15120 | 0.0080 | 94.71 | |
| Heavy Duty Degreaser C | 0.08780 | 0.0063 | 92.82 |
| 0.12900 | 0.0063 | 95.12 | |
| 0.12270 | 0.0085 | 93.07 | |
| Flux Remover C | 0.16710 | 0.0194 | 88.39 |
| 0.18970 | 0.0318 | 83.24 | |
| 0.33620 | 0.0224 | 93.34 |
Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
All three products removed over 85%.
