Note: Remove the tape from the foil. 5. After removal from oven, weigh foil and calculate weight in g/m2. (W2). Report the average of
6、three weights. 6. Calculate as follows: (W2- W,) x 100 = w, Where: W2 = Weight of foil and adhesive (g/lOO cm). W1 = Weight of foil (g/lOO cm). W,= Weight of adhesive in g/m2 Chemicals, materials, parts, and equipment referenced in this document must be used and handled properly.
