Coating Measurement and Control

Every type of coating has unique characteristics and properties that need to be carefully analyzed and monitored. These properties are influenced not only by the type of coating or surface treatment but also by the substrate it’s applied to.

Coating thickness gauges are essential tools for non-destructive measurement of coating thickness on various materials. They play a crucial role in processes where verifying the thickness of coatings, paints, galvanic treatments, and zinc layers is necessary.

One of the most important tests for coatings is checking their adhesion to the substrate. This is done using tools like cross-hatch testers or digital adhesion testers, also known as pull-off testers.

Another key aspect to evaluate is the elasticity of the coating. This is tested using coating bend testers, impact testers, or cupping testers.

Surface inspections can also assess properties like hardness or resistance to scratches and abrasions. These evaluations are performed using pencil hardness testers, pendulum hardness testers, or machines designed to test scratch resistance under constant or variable loads.

Abrasion and wear resistance is another critical aspect of coatings. This is tested using rotational, rub or solvent abrasion testers, depending on the specific requirements.
