Pull Off Adhesion Gauge
The Adhesion Test Apparatus, Model 525, measures adhesion using the adhesion test acc. to ASTM D 4541. All coating materials to which a test cylinder can be stuck with existing adhesives can be examined.
adhesive quality and tensile strength and the coating is then pulled off under defined conditions. The tensile stress required for this and a visual examination of the surface that have been separated provide therequired information of the adhesive quality of the coating.
It is to be noted that this method of measuring adhesion will give results which are not generally directly comparable with the results from other methods: the cross cutting test procedure mainly shear forces on the coating whereas the force exerted by Model 525 acts perpendicular to the surface.
The 525 B is particularly suitable for measurements on concrete surface.
