PC Pop Quiz
Posted on Tuesday, September 25, 2018
Test your powder coating knowledge interactively with others in our industry and enter for a chance to win a PCI long- or shortsleeved t-shirt!
How it works: We’ve developed questions that test your powder coating knowledge using a copy of Powder Coating: The Complete Finisher’s Handbook. PC Pop Quiz questions can be found in each issue of PCT
Put on your thinking cap and then email your answer to popquiz@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 correct answer and the lucky winner’s name will be published.
Choose the correct answer:
Q: A cure oven exhaust fan should be large enough to change the entire air volume several times per hour
to remove the byproducts of cure and combustion and prevent the accumulation of fumes. Which of the powder applications below generally requires the highest exhaust rate?
A. Non-appearance parts and dark colors
B. Clear powder coatings
C. Appearance parts and light colors
D. All require approximately the same exhaust rate
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.
Congratulations!
