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.
