Officially titled “Standard Test Method for Resistance of Organic Coatings to the Effects of Rapid Deformation (Impact),” this standard is one of the most widely referenced methods for determining how well a coating adheres under stress. astm-d2794

The weight strikes the uncoated back side of the panel, causing the coating on the front to bulge outward. This is generally considered a more severe test as it evaluates the coating's tensile strength and elongation . Evaluating Results This is where enters the chat

The coated test panel is placed over a die with a hole that matches the punch. Direct vs. Reverse Impact ASTM D2794 identifies two distinct types of impact: This is generally considered a more severe test

Impact resistance changes as a coating cures. Running D2794 tests over time helps determine the optimal "time-to-handle" or "time-to-ship" for manufactured parts.
