ABRASION TEST
Taber Abrasion is a test using a weighted abrasion wheel that rotates at a constant speed to determine the resistance of finishes to abrasion and wear, as stated by test standard ASTM D4060. Seven competitive finishes including Cerakote® H-146 Graphite Black were tested in accordance with ASTM D4060.
Based on ASTM testing standard D4060, Cerakote® Finished Strong by lasting nearly twice as long as the nearest competitive finish and 24 times as long as the further competitive finish
Gen II Coatings
COATINGS FOR NIGHT VISION CAMOUFLAGE
Cerakote Gen II coatings offer signature management and camouflage against 3rd Generation Night Vision. This LEO and Military only coating is built off the success of Cerakote H-Series Coatings, which are used by more manufacturers than any other coating.
HARDNESS
Hardness, or Pencil Hardness (ASTM D3363), is measured by using different grades of pencil lead to cut through a coating surface. To conduct this test, a coated panel is placed on a flat, horizontal surface. A weighted trolley with the hardest pencil lead (9h) is placed on the panel and pushed away from the operator. The length of the stroke should be about 6.5 mm. This process is repeated until a lead is found that will not cut through the coating to the substrate for a distance of at least 3 mm. This is the pencil hardness rating. This process is then repeated until a lead is found that will not cut nor scratch the coating (this is the scratch rating).
Cerakote® H-146 Graphite Black finished strong with a 9h hardness rating, the highest hardness rating that can be achieved.
DURABILITY
Impact Resistance (ASTM D2794) measures the resistance of organic coatings to the effects of rapid deformation (Impact). Impact resistance is measured by placing a coated panel in an universal impact tester. A standard weight is dropped a distance to strike an indenter that deforms the coating and the substrate. The indentation can be either an intrusion or an extrusion. By gradually increasing the distance the weight drops, (2 inches at a time) the point at which failure occurs can be determined by cracking or delamination of the coating.
All Cerakote Elite and nearly every Cerakote H Series have an impact strength measuring 160 inch-lbs., which is the maximum the impact tester can measure.
Adhesion
Adhesion (ASTM D3359), is a test method to analyze whether a coating has adhered to a substrate. Cerakote Elite Series and H Series coatings were applied to a set of steel panels and a crosshatch pattern was made through the coating to the substrate. Pressure-sensitive tape was applied over the crosshatch cut and then the tape was smoothed into place over the area of the incisions. The tape is then removed by pulling it off rapidly back over itself at approximately a 180° angle. The adhesion of the coating to the steel is assessed on a 0B to 5B scale (shown). Cerakote Elite and H Series coatings 'finished strong' with a 5B adhesion rating, the highest adhesion rating possible.
Cerakote® H-146 Finished Strong with a 5B adhesion rating, the highest adhesion rating possible.
