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, 0.125 in.; plastics,

0.125 in.

13. T-peel strengths were measured on 1 in. wide bonds at 73°F. The testing jaw separation rate was 20 inches per minute.

The substrates were 0.020 in. thick. (Tests per ASTM D 1876-61T.)

14. Solvent resistance was determined using cured (24 hrs RT + 2 hrs 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.
