James Bond Test™ MK IV

Determine the adhesion strength of shotcrete, epoxies, paint, asphalt and other repair materials or coatings. Includes 10 - 2" Discs.

The James Bond Tester™ MK IV or pull off adhesion test measures the bond strength or tensile strength of concrete, asphalt, tile, concrete repair, or other overlay material by the direct tension or pull off method. By pulling a 50 mm (2 inch) steel disk attached to the material under the unit can,

Measure the near surface strength of a substrate in order to determine the substrates quality before applying an overlay
Determine the bond strength of a repair or overlay material after it is applied to the substrate
Determine the tensile strength of a repair, overlay or adhesive after the material is applied to the surface

The James Bond Tester™ MK IV has been successfully used to verify the quality of existing materials, determine the adhesion strength of shotcrete, tile, epoxies, paint and other repair materials or coatings.

The alignment plate has two 360 degree bubble levels built in to facilitate set up, allowing a direct tensile pull from the surface of the material under test. The level can be easily adjusted by utilizing the thumb screws attached to the adjustment legs.

There are also two magnets that hold the pull assembly to the plate. This eliminates the tedious need for screws to keep the two assemblies together when transporting the system from one test to another. Yet it still keeps the system compact for storage and transportation.

For Proper testing, it is first necessary to cut through the overly under test directly to the substrate underneath. In the case of paints, thin coatings and overlays this can simply be accomplished with a fine exacto knife or similar sharp tool. In the case of concrete overlays, asphalts, tiles or similar repair mortars this can only be accomplished by coring saw or drill.

Failure can typically occur in either one of three modes:

in substrate
at the substrate overlay interface
in the overlay.

Tests can also be performed for verification purposes and not to failure. This will assure the engineer that both the overlay and substrate have 'bonded' and further work or use can proceed.

Bond disk will not stick to surface

Disk pops off surface at a low strength

When doing a test to check bonding strength on a roadway, do you have to take the test to failure?

When I crank the handle down, the gauge does not move.

How much epoxy do I put on the bond disk?
