#：非破坏性是指当涂层在规范内时，测量时圆形锻模折断，只留下可以剪除掉的小纽扣在涂层内。
Elcometer 109 - Tesile Adhesion Tester
The 109 has been developed for testing coatings using colour coded test elements which break at a predetermined force of 5MPa, 7MPa or 9MPa. (Other values are available on request).
If the test element breaks then the coating adhesion is acceptable. A piece of the test element will remain adhered to the surface and the colour band indicates the force the coating has withstood. If the coating breaks then the coating adhesion has failed to meet the requirements of the specification.
