KRÜSS contact angle measuring instruments use a new dosing system to measure the retraction behavior of dosed drops in a matter of seconds. The method complements conventional contact angle methods and expands the application possibilities of wetting measurement for testing material surfaces.

Unfortunately, I now have to admit that I have no idea at all about this technology, so I now have to ask what exactly or to what extent is this test method relevant to polyurethane processing – whether foamed, sprayed or cast?
Dr. Thomas Willers (Director Product & Business Strategy, KRÜSS): “The method presented in this press release is particularly relevant for PU users when finished PU products are to be further processed. For example, if PU is to be glued, printed or coated. Pre-treatment methods such as plasma or corona or cleaning are often used here. The method we have presented makes it possible to control or optimize these pretreatment processes with significantly higher sensitivity.”
