Impact testing is used to measure an objects, material, or coatings ability to resist high-rate loading, normally thought of as two objects colliding at high relative speed. A coating's ability to resist impact is one of the major determining factors in the service life of a part and/or it's suitability for an application. The ability to quantify this property is a great advantage in product . Test Standards: ASTM D7378/D7091/D4138 Film thickness is arguably the single most important measurement made during the application and inspection of protective coatings. Powder coatings are designed to perform their intended function when applied within a thickness range specified by the manufacturer.
Impact Test. Similar to the mandrel bend test, the impact test deforms a sample panel in order to test the adhesion of the powder coating. The sample panel is placed into the testing machine where a ball is dropped onto it to produce a deep depression.

ASTM G14 – Standard Test Method for Impact Resistance of Pipeline Coatings (Falling Weight Test) ISO 6272 – Paints and Varnishes - Rapid-deformation (Impact Resistance) Tests ; The impact fusion is hard to clean out. We run 10 automatic guns and two manual guns in a system that is designed to run at 12 fpm. We think we have a powder problem, but our supplier says our delivery pressures are too high. Any ideas for ways to control impact fusion would be appreciated.
If you are getting less than 2 mils, you are at risk of not providing full coverage on the product. If you are over 5-7 mils in a single coat, you could be wasting powder or causing surface appearance defects like “orange peel” or runs. In either case, adjustment of the powder coating application is needed.
