Milli Scratch Tester

Milli Scratch Tester

In accordance with JIS 3255

Scratch test instrument for adherence characterization and scratch resistance for thin coatings and bulk materials.

The scratch test method consists of scratching on the surface, with a diamond tip on which a constant or a progressive load is applied.
As the scratching is done, the sample moves under the video system, to examine the different kind of damage done by the tip.
Pictures can be digitized and positioned precisely on the loading graphs.
This standard method allows for comparison of different coatings according to substrates, thickness of coatings and preparations of surface before coating and scratch resistance of bulk materials.
