Three pre weighed stainless steel coupons were used per each soil per cleaner for a total of18 coupons. The coupons were then soiled with their respective adhesives, half being soiled with adhesive 5017 and half being soiled with adhesive 5024. The soils were heated to 245 degrees F in order to melt the adhesives to a degree that would allow for a small amount of adhesive to be picked up using a spatula. The adhesive on the spatula was then reheated using a heat gun in order for the adhesive to be able to spread on bottom third of the coupons. The dirty weights of the coupons were then recorded.
The coupons were then subjected to 45 minutes of unheated immersion with a stir bar set at 200 rpm in their respective cleaners. Once the coupons were removed from the cleaners, a manual wipe step was utilized (a singular wipe with a paper towel).
All coupons were allowed to air for 30 minutes before final weights were recorded.
