PC Pop Quiz July-August 2017

Welcome back to PC Pop Quiz—the department in Powder Coated Tough that is designed to test your general powder coating knowledge while competing against industry colleagues! When you joined The Powder Coating Institute, you received Powder Coating: The Complete Finisher’s Handbook. It’s time to put it to use and compete with your colleagues for a chance to win your own limitededition PCI long- or short-sleeved t-shirt!

How it works: The staff at PCT has used the handbook to come up with questions that will test your powder coating knowledge.

We present the questions here, in this section, of every issue of PCT. When you think you know the answer, email it to editor@powdercoating.org using the subject line “PC Pop Quiz.” All correct answers received by the deadline will be entered in a drawing to win an official PCI long- or short-sleeved t-shirt. In each subsequent issue of the magazine, the question, its correct answer, and the lucky winner’s name will be published. All answers can be found in Powder Coating: The Complete Finisher’s Handbook. Ready?
