ASTM Paint Adhesion Testing

ASTM Coating Adhesion Testing

Coatings must adhere to the substrates they are applied to perform satisfactorily. ATS offers a variety of ASTM coating adhesion testing capabilities to help clients optimize the functionality of their coating applications and avoid premature failure. Our testing services save clients money, providing them with the data necessary to pick the right coating and effectively protect their products, equipment, and infrastructure.

Test Methods:

Pull-off Test — This procedure is accomplished by sticking a loading fixture perpendicularly to the coating, then slowly increasing tensile load until either the fixture and adhesive layers are removed or until a predetermined value is reached.

Knife Test — This procedure is accomplished by making two cuts into the coating with a utility knife to form an “X” shape. The coating is then lifted at the vertex, using the point of the knife.
Scrape Test — This procedure is accomplished by loading a rounded stylus or loop onto a balanced beam scrape adhesion tester at a 45-degree angle, then increasing the load until the stylus removes the coating from the surface of the substrate.
Tape Test — This procedure is accomplished by cutting either an X shape (method A) or a lattice pattern (method B) into the coating, then applying pressure sensitive over the cuts and removing it.
