E. Overlap Shear Strength on Abraded Metals, Plastics, and Rubbers.

Overlap shear strengths were measured on 1" x 1/2" overlap specimens. These

bonds were made individually using 1" by 4" pieces of substrate (Tested per

ASTM D 1002).

The thickness of the substrates were: cold rolled, galvanized and stainless steel –

0.056-0.062", copper – 0.032", brass – 0.036", rubbers – 0.125", plastics – 0.125".

All surfaces were prepared by solvent wiping/abrading/ solvent wiping.

The jaw separation rate used for testing was 0.1 in/min for metals, 2 in/min for

plastics, and 20 in/min for rubbers.
