Hardness Tester For Coatings - Durometers
The Buchholz and Wolff Wilborn hardness tests
Measuring the hardness of a coating can represent a fundamental parameter for guaranteeing the durability and quality of a paint job.
For this application there are instruments, such as the Buchholz durometer, capable of carrying out a hardness test on coatings compliant with the ISO 2815-2003 standard.
Another widely used and effective test is also the "Wolf Wilborn" which exploits the principle based on the scratching method using pencils of different degrees of hardness.
The coating hardness testers on sale in our shop are instruments compliant with the standards: ASTM D 3363, BS 3900-E19, DIN EN 13523-4, ECCA T, ISO 15184
How to perform a hardness test on a coating
- Buchholz; The test consists of using a metal cutting edge positioned on the sample to be tested with a calibrated weight and left for a certain period of time. The length of the incision left on the coating surface compared in the Buchholz table will provide the reference value expressed in "BH". Mandatory tests carried out in Qualicoat, QIB and GSB accredited laboratories.
- Wolf Wilborn;The pencils, selected with different degrees of hardness, are housed inside a special carriage with an inclination angle of 45°, which is slid on the painted surface with a predefined force. The value is then detected based on the scratch released on the coating.
