The Micro Scratch Tester MST³ is widely used to characterize the practical adhesion failure of thin films and coatings with a typical thickness below 5 μm. The Micro Scratch Tester is also used in the analysis of organic and inorganic coatings as well as soft and hard coatings.
Applications include thin and multilayer CVD, PVD, PECVD, photoresist, lacquers, paints, and several other types of films. Research areas and industries utilize this instrument for microelectronics, optical coatings, protective and decorative surface coatings. Substrates may be soft or hard, including glass, semiconductors, refractive and organic materials.
