Adhesion Testers

Paint Adhesion Testers

In order to perform satisfactorily, coatings must adhere to the substrates on which they are applied. There are three different adhesion test procedures to assess the resistance of paints to separate from the substrate. The cross cut test, also described as cross-hatch, uses a blade to cut through the coating to the substrate. At least two cuts are made that intersect at 90 degrees to get a right angle lattice pattern. The cross-cut area is observed for any adhesion failure. The second method to test the coating adhesion is using a stylus or loop that an increasing amount of weight is applied until the coating is removed from the substrate. The third method called pull-off adhesion, measures the amount of tensile stress to pull the coating off the substrate. A dolly is glued to the coating surface.

Cross-cut Tester, 1-edge

Hoffman Scratch
Hardness Tester

The crosshatch paint adhesion test kits have a wide selection of cross-cut blades to comply with the appropriate ASTM and ISO coating adhesion test methods.
The crosshatch paint adhesion test kits also have the one edge blade option to comply with the appropriate ASTM and ISO coating adhesion test methods.
The Hoffman Scratch Tester is economical paint adhesion tester.
