Footnotes:

12. 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. The thickness of the

bond line was 0.005-0.008 in. All

strengths were measured at 70°F

except were noted. (Test 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.; rubber, 0.125in.;

plastics, 0.125 in.

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

conditions specified. The following data show typical results obtained with the 3M™

Scotch-Weld™ Adhesives when applied to properly prepared substrates, cured, and

tested according to the specifications indicated. The data was generated using the 3M™

EPX Applicator System equipped with an EPX applicator static mixer, according to

manufacturer’s directions. Thorough hand mixing should afford comparable results.

Note: The following technical information and data should be considered representative

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