A practical overview of inspection points for polyurea coatings on steel, concrete, and other substrates, including surface profile, climate, thickness, and adhesion.

In an automotive repair shop, cleaning, restoration, and protection are closely connected to the actual condition of the painted surface. For light scratches, swirl marks, stains, tree sap, paint overspray, or oxidation, technicians may consider polishing to improve the appearance. However, both polishing and sanding affect the coating. Therefore, an automotive paint thickness gauge is an important supporting tool before, during, and after surface treatment.

Using a coating thickness gauge helps identify wear on an OPC printer drum rather than relying solely on visual inspection of the surface. The service life of an OPC drum is often considered to have significantly declined when the coating has worn by approximately 5 to 15 μm. When the wear approaches half of the original coating thickness, the drum may be removed from service depending on the remanufacturer’s quality control procedures.

A practical guide to selecting a conformal coating thickness measurement approach for printed circuit boards based on substrate construction, available access, and coating requirements.

Erosion and corrosion can gradually reduce the material thickness of pipelines, storage tanks, boilers, pressure equipment, and various other industrial structures. Ultrasonic thickness gauges also provide the basis for identifying areas of wall thinning, planning inspections, and supporting maintenance decisions.

Accurate paint thickness measurement helps collision repair teams control refinishing work on plastic bumpers and fascias that incorporate ADAS sensors.
