TRACTION PAD FOR DEVICE TESTING ADHESION OF A COATING ON A SUBSTRATE

摘要

The invention concerns a traction pad to be bonded for coating adhesion or surface cohesion tests by tearing comprising a counterbore designed to control the thickness of the adhesive film. Support elements such as wedges or a border maintain the base of the counterbore at the required distance from the tested surface and openings are provided for evacuating the adhesive prior to its controlled hardening when the traction pad is applied on the tested surface.
