Test: ASTM D3359
Adhesion (ASTM D3359) is a test method to analyze whether a coating has adhered to a metal substrate. Cerakote MC-160 and H-300 were applied to a set of steel panels and a crosshatch pattern is made through the coating to the substrate. Pressure-sensitive tape is applied over the crosshatch cut and then the tape is smoothed into place over the area of the incisions. The tape is then removed by pulling it off rapidly back over itself as close to an angle of 180* and the adhesion of the coating to the steel is assessed on a 0B to 5B scale (shown). Cerakote MC-160 and H-300 Finished Strong with a 5B adhesion rating, the highest adhesion rating possible.
