Clear coatings abrasion test design

Petition / Problem

Customer needs to determine the abrasion resistance of a clear coating on a clear substrate.

Objective

Design an abrasion test and measurement method to compare the resistance of coatings.

ATRIA solution

Various abrasion methods were designed taking into account the geometry of the parts and the available equipment. Devices capable of measuring the thickness of transparent coatings were found on transparent substrates with nanometric precision.
