How to perform a bond test

Com-Ten is an instigator in the validation of installation of insulation membrane, with the Uplift tester, and the measurement of the bonding strength of coatings, with the Adhor tester. These products are design to proof the good installation and property of adhesion directly in the field.

A clean disc is glued on the planed, cleaned surface (using an epoxy resin). A curing period of 24 hours is needed to ensure a good bonding of the adhesive.
This disc is grabbed by the pull tester using a female slotted adaptor which stays at the base of the pull tester. Then the disc is pulled off in direct tension using the hand crank of the Adhor tester. The gauge displays and registers the peak pull out force break of the coating on its substrate.
