Bond test

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.
