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

21°C (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. perminute 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,

0.125 in.; plastics, 0.125 in.

13. Solvent resistance was determined

using cured (24 hrs RT + 2 hrs

71°C [160°F] samples (1/2 in. x 4

in. x 1/8 in. thickness) immersed in

the test solvent for 1 hour and 1

month. After the allotted period of

time the sample was removed and

visually examined for surface

attack as compared to the control.
