The question for the July/August edition of PC Pop Quiz, along with the answer is:

Q: The pigment volume concentration (PVC) in powder coatings is relatively low compared to liquid coatings and seldom exceeds 25%.

A: The answer is: True. You will find on page 416 of the Powder Coating Handbook the PVC in powder coatings is much lower compared to liquid coatings. Higher levels of pigments in powder coatings significantly increase viscosity, reducing the flow of powder coatings and resulting in heavy orange peel or a rough, grainy coating.

The number of respondents we get for PC Pop Quiz continues to grow. We even see a few college students have started to play! We appreciate all those who took the time to participate.

This month’s winner is: Karen Schneider, Applications Technology Manager, Business Unit Coatings & Plastics, Schlenk Metallic Pigments. The t-shirt you selected is on its way.
