Portable Calibration Unit
Calibration unit designed for calibrating and checking the accuracy of the PAT adhesion testers. (With adaptors other makes of pull-off testers can also be checked).
Two cylinders with Ø25mm/one inch diameter, one of which is coated with the sample coating, are glued together end-to-end and then pulled apart in order to measure the pull stress (measured in Newton/mm2 or psi) required to fracture the coating.
The ASTM-C633 tensile testing jig is used with the PAT range of pull-off testers to perform pull testing in accordance with ASTM-C633. Go to page about ASTM-C633.
Glue Curing jig
Failure to glue the cylinders together absolutely concentrically will result in imbalance in the stress distribution over the tested interface between the two test cylinders with a resulting lower fracture value.
Jig for heat-curing (in an oven) assembly of pairs of test cylinders glued together.
This jig will not only ensure a 100% concentric joint but also ensure that the glue is evenly spread between the test cylinders.
Shear Testing Jig
Jig for testing a coating in shear mode, i.e. pulling the test element sideways parallel to the substrate until fracture occurs.
