Five Critical Questions to Ask About Pinch Testing Data

Pinch testing data can be used to make or break a lubricious hydrophilic coating. It can also be used to lie. When you see any graph depicting lubricity and durability for a coating, it is time to stop and take a breath before absorbing the data. Ask yourself about the nature of the test used to get the information.

Some hydrophilic coatings can be painted as amazingly slick and durable, but when put to a rigorous test, not so much. Others shine and duke it out among the top. I will soon be publishing a white paper demonstrating how differences in testing methods can make big variations in friction outcomes. Below is a preview table of the 5 questions to ask yourself whenever you view friction data for a lubricious coating.
