  • How to Test Parylene Adhesion - Diamond-MT

    ASTM D3359 – Tape Testing For AdhesionKnife, Pull-Off, and Scrape TestsConclusionThe Tape Test consists of two variations: 1. X-Cut Tape Test: A technician applies a utility knife and straightedge to mark the parylene coating with two intersecting, small-scale cuts, situated at angles of 30-45 degrees to the surface. The cuts need to penetrate to the substrate surface, forming an “X” shape. Tape is placed at the X’s vertex (where the lines intersect), and then is briskly pulled from the cut surface. The center of the “X” is then inspected to see if the tape caused any of the parylene to pull away from the component’s surface, indicating poor adhesion. 2. Cross Hatch Tape Test: Typically applied in a clinical setting, cross-hatched parallel lines rather than an X are cut into the coating, using either a customized cross-hatch cutter, or a utility knife/straightedge. The result is a series of slightly raised squares across the coating surface, where the cross-hatched lines intersect. Here again, tape affixed to the surface is rapidly removed. If any of the squares...
