Characteristics

Note: The following product performance data was obtained in the 3M laboratory

under the conditions specified. The following data shows typical results obtained

with 3M™ Scotch-Weld™ Epoxy Adhesives DP-100 and DP-100 NS when applied

to properly prepared substrates, cured for 7 days at 23°C (73°F) under 2 psi cure

pressure, and tested according to the test methods indicated.

The following technical information and data should be considered representative

or typical only and should not be used for specification purposes.

A. Overlap Shear

Overlap shear (OLS) strengths were measured on 1 in. wide 1/2 in. overlap

specimens. These 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 2024 T-3

clad aluminum were bonded and cut into 1 in. wide samples after 24 hours. The

thickness of the bond line was 0.005 - 0.008 in. All strengths were measured at

23°C (73°F) except where noted. (Tests per ASTM D 1002-72.)

The separation 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

T-peel strengths were measured on 1 in. wide bonds at 23°C (73°F). The testing

jaw separation rate was 20 inches per minute. The substrates were 0.032 in. thick.

(Tests per ASTM D 1876-61T.)

C. Cure Cycle

With the exception of Rate of Strength Build-Up Tests, all bonds werecured

7 days at 23°C (73°F)/50% RH before testing or subjected to further conditioning

or environmental aging.
