Durability Impact Test for Cerakote Coatings

Cerakote Gun Coatings Durability ASTM: D2794

Cerakote 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 a universal impact tester. A standard weight is dropped from 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 from which the weight is dropped (1 inch at a time), the point of failure can be determined by observing cracking or delamination 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.
