Trial Purpose:
To evaluate new product on graphite mold release agent using ultrasonic cleaning.
Date Run:
08/15/2005Experiment Procedure:
One product was selected based on similar product make up to successful product in previous trial. The product was diluted to 10% using DI water in 600 ml beakers based on vendor recommended concentration. The product was heated to 130 F on a hot plate.
Three preweighed aluminum coupons were coated with the Acheson Colloids Co Aquadag M mold release agent (CAS#: 7782-42-5, 84122-50-6, 70131-67-8, 1333-86-4, 107-21-1, 9002-84-0). The mold release was initially dried for 5 minutes using a Master Appliance Heat Gun at 500 F. The coupons were then subjected to another 10 minutes of drying. Coupons were not allowed to sit overnight but were heated for 2 hours in an oven at 500 F. After the drying, coupons were allowed to cool to room temperature and weighed a second time to determine the amount of soil added to the coupons.
Three coupons were cleaned in the solution for 5 minutes using ultrasonic agitation. Coupons were rinsed in a tap water bath for 15 seconds at 120 F and dried using compressed air blow off at room temperature for 30 seconds. Final weights were recorded and efficiencies were calculated.
Trial Results:
The Metal Bright removed nearly 80% of the graphite mold release from the aluminum coupons. The table lists the amount of soil added, the amount remaining and the efficiency for each coupon cleaned.
| Cleaner | Initial wt | Final wt | % Removed |
| Metal Bright | 0.0062 | 0.0017 | 72.58 |
| 0.0096 | 0.0014 | 85.42 | |
| 0.0108 | 0.0020 | 81.48 |
Success Rating:
A follow up test, usually based on company input.Conclusion:
The Metal Bright will be used to clean supplied aluminum parts using ultrasonics.
