adhesion, and premature coating failures. This is why we test coating hardness, as this indicates how well it has cured – typically the harder the coating, the more complete the cure, and the better its overall performance. One of the most common methods of determining coating hardness is the pencil hardness test, alsoInterchangeability: PosiTector body accepts all PosiTector BHI, SHD, 6000, 200, IRT, DPM, RTR, SPG, SST, and UTG probes easily converting from a hardness tester to a coating thickness gage, dew point meter, infrared thermometer, surface profile gage, soluble salt tester, or ultrasonic wall thickness gage.

The pencil hardness test, also referred to as the Wolff-Wilborn test, uses the varying hardness values of graphite pencils to evaluate a coating’s hardness. The Elcometer 501 Pencil Hardness Tester has been designed to ensure that the cylindrical pencil lead is maintained at a constant angle of 45° and exerts a force of 7.5N (1.68lbF).
Some environments and applications are too harsh for some coatings, so conducting hardness testing is essential to ensure the coating hardness is appropriate for the desired application. ASTM D3363. ASTM D3363 is the standard method for pencil hardness testing. The test method evaluates coating hardness on a spectrum ranging from B (soft) to HB .A cross hatch test (cross cut) is fast and simple to perform with an inexpensive cross-hatch cutter test kit. A lattice pattern is cut into the finish film down to the substrate, using a cross-hatch cutter. .

R 6 en 2.6 CHANGE PENCIL HARDNESS If no marking has occurred repeat the test (2.2 to 2.5) with the next hardest pencil. Note: If using the ASTM D 3363 method and the lead has cut through or scratched the surface of the coating, select the . This is typically done for coatings where surface testing is not possible or when additional analysis is required such as analysis of through-thickness hardness, for inspection of interface contamination, or for inspection of coating properties such as porosity, phase analysis or multiple layers. Typically applied on both sides of an eyeglass lens, this coating, also known as AR or anti-glare, “reduces the amount of light reflected off the surfaces of spectacle lenses, and may enhance .
