Each pen uses a valve tip applicator, this keeps the felt tip sealed from the ink reservoir when not in use, unlike traditional marker style pens which allow contaminants to wick back up the tip.
Dyne Test Inks and Dyne Pens are a quick and easy way to measure the surface energy of a material.
Standard values for both the 15ml pens and 30ml bottles are available in even numbers from 30 to 72 dyne. There’s also a range of applicators and techniques depending on your material and the surface you’re trying to measure. From trying to measure fine fibres and cables, to checking the quality of incoming steel rolls, there’s a way to do it.
Following ISO 8296 for PE, you can alter your approach the get a consistent and sensible result every time.
