The average bondline temperature during the cure time will be somewhat lower than the oven temperature. 2 The value in the denominator is the expected minimum 73F (23C) T-peel strength (piw) measured after the indicated cure cycle. NOTE: The data in this Technical Data Sheet were generated using the 3M EPX Applicator System equipped with an EPX static mixer, according to manufacturers directions. Thorough hand-mixing will afford comparable results. 2
