New Product Release - The James Bond Test ™ MK IV

Chicago, IL USA June, 8, 2020. 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 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

Standards :
  • ISO 4624 Paints and varnishes -- Pull-off test for adhesion

  • EN 1015-12 Methods of test for mortar for masonry. Determination of adhesive strength of hardened rendering
    and plastering mortars on substrate

  • EN 1348 Determination of Tensile Adhesion Strength for Cementitious Adhesives

  • BS 1881 Part 207 Testing concrete. Recommendations for the assessment of concrete strength by near-to-surface tests

  • ASTM C 1583 Standard Test Method for Tensile Strength of Concrete Surfaces and the Bond Strength or Tensile Strength of Concrete Repair and Overlay Materials by Direct Tension (Pull-off Method
  • ASTM D 4541 Standard Test Method for Pull-Off Strength of Coatings Using Portable Adhesion Testers

  • ACI 548-30 Guide for the Application of Epoxy and Latex Adhesives for Bonding Freshly Mixed and Hardened Concretes

  • DIN 1048 Part 2 Testing concrete; testing of hardened concrete (specimens taken in situ)

  • ASTM D 7234 Standard Test Method for Pull-Off Adhesion Strength of Coatings on Concrete Using Portable Pull-Off Adhesion Testers

The James Bond Tester™ MK IV 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.
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.

Features and Benefits:

  • Accurate bond strength of repair mortars, epoxy resins, laminates, overlays, and other coatings.

  • Calibrated gauge with maximum load indicator and mechanical damping.

  • Ball Joint Design for rapid testing as well as assuring direct tensile loading

  • Adjustable alignment plate with built in leveling facility for both vertical and horizontal pulls.

  • Compact design.

  • Easy to use.
