Pinch Testing White Paper Released

Posted by Josh Simon on Fri, Feb 24, 2012 @ 03:39

As promised, and not long after my last message, I present to you our newest white paper on Pinch Testing.  In its pages, you will come to understand what kinds of parameters govern the pinch test, with regard to hydrophilic coatings.

This paper is an attempt on my part to educate engineers in the field about how to choose a coating based on pinch test data.  For a few years now, I have encountered pinch test data from various companies that portray hydrophilic coatings in a durable and lubricious light.  The problem I saw with some of that data is that it was misleading.  In some instances, it did not give the conditions of the test.  Heck, it sometimes seemed like the authors of the data did not even know there were any test conditions in some cases.  They merely touted it as if it were sliced bread, but better.

That makes it rather difficult to tell the good coatings from the bad.  They are all more or less lubricous, but whether or not they can stand up to abrasion is not honestly portrayed in all cases.  It is my hope that this article would shed some light on that.
