Trial Purpose:
To evaluate the effectiveness of Fluosolv NC-786 at removing wax and lubricants from aluminum alloys.
Date Run:
08/16/2017Experiment Procedure:
Preweighed aluminum coupons were tested for each aqueous cleaner. Five soils were tested: Lenox Lube Tube Wax (CAS:8002-74-2; 57-11-4; 5989-27-5) Blasocut 2000 Universal Lubricant (CAS: 64742-52-5; 61790-44-1; 68608-26-4; 63449-39-8; 107-41-5; 770-35-4); Accu-Lube LB 6000 Lubricant (CAS68583-51-7); Oak 7a lubricant (CAS: 64742-53- 6; 68909-65-9); and Rustlick EDM30 lubricant (CAS:64742-47-8; 8042-47-5). Coupons were soiled using a swab to cover the bottom third of the substrate and dirty weights were recorded. Coupons were immersed, three at a time, in a heated beaker (80 F) filled with 200ml of Fluosolv NC-786 for five minutes. Dirty weights were recorded after testing.

Success Rating:
Preliminary compatibility tests on substrate coupons encouraging for at least one cleaning chemistry. More in-depth laboratory testing necessary.Conclusion:
Fluosolv NC-876 was effective in cleaning all five soils using immersion at 80 F for five minutes.
