Q&A About Polyurethanes: Formulating Basics for Coatings
What are some fundamental issues that I should know regarding the basics of formulating coatings?
An important concept to learn is critical pigment volume concentration (CPVC). Understanding this concept is essential for formulating high-performance coatings. In fact, it’s an “elephant in the room” for many formulators—ignored at our peril.
Recent articles1,2 on CPVC are timely: many coatings formulators from the last 30-40 years have since retired or moved into other areas of the industry. As a result, those who remain or are just beginning their formulator careers need to be educated in key aspects of coatings technology. CPVC is one of those key aspects that needs recognition and respect.
