Coating Adhesion and Cross Hatch Test governed by ASTM D3359

Let's take a look at how to test if the core plate coating is properly cured. We will demonstrate two sets of testing to ensure that the coating is ready for release into production. First, we will take droplets of deionized water and apply them to various parts of the surface. After an extended period, we will remove the water and check for any residual or visual indication that the coating is not cured. Second, we will apply ethanol to a clean surface and perform a series of rubs on the part to ensure that the coating is not affected. We will also check if the coating adheres correctly to the metallic substrate using the cross hatch tape test. Lastly, we will verify the adhesion loss against the range set forth in ASTM D3359. This video is perfect for those who want to learn how to properly test the curing of core plate coating.
