James Bond Test MK III in use on Concrete

The James Bond Tester MK III 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 25mm steel disk attached to the material under the unit can,

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

The James Bond Tester MK III 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.

Adequate direct tensile strength between two layers is important if repairs to concrete structures or additional overlays on existing concrete are to be structurally sound. The James Bond Tester MK III involves bonding a circular steel disk to the surface by means of an epoxy resin adhesive. A controlled tensile force is then applied to the disk and failure will occur at the weakest point: either in the host material, or in the bond between overlay and host material.

Easy to read gauges facilitate performing the test. Two gauges are supplied with each system. One for lower strength ranges, weaker concrete, painted on overalys, etc. The other for higher strength overlays, and concrete, mortar and asphalt repairs. These guages feature

  • Rubberized Rugged Outer Housing
  • Quick Disconnect for Rapid Setup
  • Maximum Load Indicator
  • Mechanical Damping to Minimize Test Error

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.

Core Indicating Failure at the Bond Between the Overlay and Substrate

For Proper testing, it is first necessary to cut through the overly under test directly to the substrate underrneath. 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.

James Bond Tester MK III features a ball joint pull disk design. This assures that the pulling force is always in tension even if the pull disk is uneven due to irregularities in the overlay surface. This also creates a rapid test setup as the ball end of the disk simply slide into the Bond Test Puller.
