Reduce Cross Hatch Testing

Coating adhesion control beyond ISO 2409/ASTM D 3359

Is your adhesion test only scratching the surface?

 

Destructive, cumbersome, subjective, and an analog relic from the last century: Do you feel the same way about the cross hatch adhesion test , but can’t do without it? Maybe you can!

Introducing the Stood-up Drop®, a non-destructive prescreening method that helps reduce the number of tests according to ISO 2409/ASTM D 3359 – or even replace them altogether.

Replacing blades with drops of water: the Stood-up Drop

The Stood-up Drop is a dosing and evaluation solution for KRÜSS contact angle instruments. It measures the dewetting behavior of a water droplet on the sample. In an extensive study together with coating experts from BYK, we could prove that the results correlate very well with cross hatch ratings.

How to use your new adhesion testing tool

Integrating the Stood-up Drop into your testing routine is easy:

1. Check what Stood-up Drop results (recently receded contact angle; RRCA in degrees) you get for your samples.
2. Compare them with your cross hatch ratings and determine the correlation.
3. Reduce cross hatch testing with quick prescreenings of your samples with the Stood-up Drop.
