The Influence of Surface Roughness on Wettability in Paper and Board

Posted by Anna Oom on June 23, 2015

 

Did you know that surface roughness affects paper and board wettability? Due to their fiber-like structure, paper and board surfaces almost always have a surface with roughness. This roughness inherently affects the wettability as it amplifies the wetting effect of the surface chemistry. For hydrophilic surfaces, added surface roughness makes the surface further hydrophilic whereas with hydrophobic surfaces the effect is reversed.

6 Reasons to Measure Wettability in Paper and Board Quality Control

Posted by Anna Oom on June 11, 2015

 

The parameters that are being measured in quality control of paper and board may differ for several reasons; what applications the paper is made for, available instrumentation, traditions etc. If you haven’t thought about measuring wettability and adhesion properties of your paper, here are 6 reasons to start doing so.
