Ronexprim, together with our external partner, KRÜSS GmbH have the pleasure to take part in the 3rd webinar:
Stood-Up (part III): Coatings Testing Beyond Cross Hatch
Have you ever thought that the cross hatch test, as a manual, analog, and highly user-dependent procedure, is no longer up to date? We at KRÜSS certainly do. However, it is clear that a modern method of testing adhesion of coatings must be comparable with the long-established cross hatch procedure and cannot simply replace it without transition.
This 3rd part of our webinar series on the Stood-up (SUD), this time in conjunction with BYK and Plasmatreat, shows why dewetting analysis with the SUD has the potential to become this new method. Extensive comparative measurements of the recently receded contact angle (RRCA) from the SUD with cross hatch data show an excellent correlation throughout.
In this webinar we will guide you through the course of these investigations, present the results, and also quantify the influence of plasma treatments of the polymer substrates based on the SUD and cross hatch results.
Speakers
• Dr. Andrew Mellor - Applications & Markets Manager at KRÜSS
• Petra Della Valentina - Chemical Technician at BYK-Chemie
• Dennis Walker - Sales Technical Team at Plasmatreat
What you can expect
• Why does it make sense to compare cross hatch results with the SUD, which captures dewetting?
• Why is the RRCA a reliable indicator for coating adhesion and the effect of plasma treatment?
• How can the strong correlation between the RRCA and cross hatch tests to be used to replace the latter?
• What advantages would this replacement have?
