This reprents the oven temperature to which the bonds were subjected for the prescribed time. 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 73°F (23°C) T -peel strength (piw) measured after the indicated cure cycle.
NOTE:The data in this T echnical Data Sheet were generated using the 3M™EPX™Applicator System equipped with
an EPX static mixer, according to manufacturer’s directions. Thorough hand-mixing will afford comparable results.

Typical Adhesive Performance Characteristics
Note:The following technical information and data should be considered reprentative or
typical only and should not be ud for specification purpos.
Substrates and Testing
A.Overlap Shear (ASTM D 1002-72)
Overlap shear (OLS) strengths were measured on 1 in. wide 1/2 in. overlap specimens. The bonds were made individually using 1 in. x 4 in. pieces of substrate except for aluminum. Two panels 0.063 in. thick, 4 in. x 7 in. of 2024T-3 clad aluminum were bonded and cut into 1 in.wide samples after 24 hours. The thickness of the bondline was 0.005-0.008 in. All strengths were measured at 73°F (23°C) except where noted.
The paration rate of the testing jaws was 0.1 in. per minute for metals, 2 in. per minute for plastics and 20 in. per minute for rubbers. The thickness of the substrates were: steel, 0.060 in.;other metals, 0.05-0.064 in.; rubbers, 0.125 in.; plastics, 0.125 in.B.T-peel (ASTM D 1876-61T)
T-peel strengths were measured on 1 in. wide bonds at 73°F (23°C). The testing jaw paration rate was 20 inches per minute. The substrates were 0.032 in. thick.C.Bell Peel (ASTM D 3167)
Bell peel strengths were measured on 1/2 in. wide bonds at the temperatures noted. The testing jaw paration rate was 6 in. per minute. The bonds are made with 0.064 in. bonded to 0.025 in.thick adherends.D.Cure Cycle
With the exception of Rate of Strength Build-Up Tests, all bonds, were cured 7 days at 73°F (23°C) at 50% RH before testing or subjected to further conditioning or environmental aging.Aluminum, Overlap Shear, at Temperature (PSI)
