The one product was used at full strength and heated to 150 F in a Branson 3510 ultrasonic tank.
Three contaminants were applied to separate sets of coupons. The first set was coated with RPM Wood Finishes Group - MS2664 Catalyst White (108-10-1, 28182-81-2, 822-06-0) and 9-6LP9258 White Primer Topcoat (13463-67-7, 110-43-0, 123-86-4, 108-10-1, 108-38-3) in the ratio of 3 parts to 1. The second paint mix from RPM Wood Finishes Group - MS2664 Catalyst White (108-10-1, 28182-81-2, 822-06-0) and MS2669 Primer (108-10-1, 28182-81-2, 822-06-0) in the same 3 to 1 ratio. The third paint mix was from Westfield Coatings Company - ARC Fast Dry Catalyst (123-86-4, 110-43-0, 108-65-6) and Fast Dry (108-10-1) in a 2 to 1 ratio.
Each paint mix was applied to three preweighed steel coupons and allowed to dry. Three painted coupons were immersed in the cleaning product and cleaned for 10 minutes using a 40 kHz ultrasonic tank. After the cleaning, coupons were rinsed in a tap water bath for 15 seconds at 120 F and air dried for 30 seconds at room temperature. Once dry, the coupons were weighed a final time and removal efficiencies were calculated.
