Patent ID: 8375780

Claim:
In a device for measuring the adhesive quality of a coating using a coating adhesion test traction pad, the improvement comprising a coating adhesion test traction pad comprising: a lower bonding surface to be bonded on a surface of the coating prior to testing using an adhesive and defining a plane orthogonal to a reference traction axis of the coating adhesion test traction pad; a counterbored recess in the lower bonding surface, the counterbored recess having a substantially constant depth; spacing means between the lower bonding surface and a bottom of the counterbored recess, the spacing means having a height corresponding to a thickness of an adhesive to be provided between the coating adhesion test traction pad and the surface of the coating to be tested, the spacing means comprising a material similar to a material of the coating adhesion test traction pad; and at least an adhesive evacuation opening to let excess adhesive flux out of a bonding area defined by a mark of the traction pad on the surface of the coating, the at least one adhesive evacuation opening comprising one or more exhaust stacks extending into a body of the coating adhesion test traction pad.
