5、wing application of adhesive, remove foil and place them in a convection oven at 180 OF for four hours. Note: Remove the tape from the foil. 5. After removal from oven, weigh foil and calculate weight in ozlsq yd. Report the average of three weights. 6. Calculate as follows: W2 - W1 = W3 (W3) . (2.8
6、6) = x Where: W2 = Weight in grams of foil and adhesive/l6 sq. in. section W1 = Weight in grams of foil/l6 sq. in. section W3 = Weight in grams of adhesive/l6 sq. in. section X = weight of adhesive in ozlsq yd. Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly. Each party is responsible for determining proper use and handling in its facilities.
