Cerakote Gun Coatings Durability Astm: D2794
Impact resistance (astm D2794) measures the resistance of organic coatings to the effects of the rapid deformation (Impact). Impact resistance is measured by placing a coated panel in a universal impact tester. A standard weight is dropped a distance to strike an indent-er that deforms the coating and the substrate.
The indentation can be either and intrusion or an extrusion. By gradually increasing the distance the weight drops, (1 Inch at a time) the point at which the failure occurs can be determined by cracking or de lamination of the coating. Cerakote H-146 Graphite black was tested to have an impact strength measuring 160 Inch-lbs which is the maximum the impact tester can measure.
