Trial Purpose:
To evaluate TCE drop-in replacements for vapor degreasing operation.
Date Run:
05/05/2004Experiment Procedure:
Twelve cleaners were selected based on client request for vapor degreasing solvents. All twelve products were used heated to 96 F on a hot plate in 250 ml beakers. The process utilized no water rinse and only used ambient air to dry the parts. Thirty-six preweighed steel coupons were coated with Castrol Quench G oil (64742-55-8, 64742-65-0, 8052-42-4) using a hand held swab. The quench oil was then heated with a Master Appliance Heat gun at 300 F for 10 minutes. After cooling to room temperature, a second weighing was performed to determine the amount of soil that was added. Three coupons were cleaned in each solution for 5 minutes with minimal stir-bar agitation. After drying, coupons were weighed a final time to determine the cleaning efficiency of each product.
Trial Results:
All twelve products removed over 90% of the quench oil within five minutes of cleaning. Nine products removed over 95% and five removed over 98%. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.

Success Rating:
Results successful using TACT (time, agitation, concentration, and temperature, as well as rinsing and drying) and/or other cleaning chemistries examined.Conclusion:
The nine products that removed over 95% of the soil will be tested on Rochester Midland RI 780 rust preventative under the same conditions.
