Adhesion Test Jig

This Adhesive Test Jig and Anchor Plate shown above were developed to enable the testing of adhesives or other uncured coatings. The process is as follows: 1) Thread up to 5 pull-stubs into the base of the Adhesive Test Jig 2) Apply the adhesive or coating to be tested to several pull-stubs (up to 5 at a time). 3) Place the coated pull-stubs face-to-face with the uncoated stubs resting in the Adhesive Test Jig, effectively "sandwiching" the adhesive or coating between the stubs 4) Tighten the nuts on the top of the Adhesive Test Jig until the desired pressure is applied while the adhesive or coating cures 5) Remove the pull stubs from the Adhesive Test Jig after the adhesive or coating has cured and thread one end into the Anchor Plate 6) Attach a piston to the threads of the pull-stub protruding from the Anchor Plate and use the PATTI as usual 7) When separation occurs, the PATTI will display the Burst Pressure of your adhesive or coating, and this is easily converted to tensile strength using the piston conversion charts
