Portable Plural-Component Coating Systems for Contractors

Course Assessment

Assessment Instructions

  • Answer all 24 questions.
  • Select the best answer for each question.
  • A score of at least 80 percent is required to pass.
  • You must answer at least 20 questions correctly to pass.
  • You may review the course and retake the assessment if necessary.

1. What is the primary purpose of a plural-component proportioner?

2. Why are the two components normally kept separate until near the point of application?

3. What determines whether a plural-component system is suitable for a particular coating?

4. Which document should govern the required component ratio?

5. Why must a contractor distinguish between a ratio stated by volume and one stated by weight?

6. What is the principal advantage of locating a remote mix manifold closer to the spray gun?

7. What is a major risk when one component’s supply pump loses prime?

8. What can excessive agitation introduce into a liquid coating?

9. Why is material temperature controlled in plural-component application?

10. What is the function of a static mixer?

11. Which statement about high-pressure fluid hoses is correct?

12. Why are grounding and bonding important during coating and solvent handling?

13. What does calibration establish?

14. What is the strongest evidence that a system is delivering the required component ratio?

15. What should be done before reactive components enter the mixed-material circuit?

16. What is the correct approach to establishing airless spray pressure?

17. Which gun technique is most likely to produce uniform film thickness?

18. A coating requires 16 mils DFT and is 80 percent solids by volume. What is the approximate required WFT?

19. What should a contractor do when the maximum recoat window has been exceeded?

20. What is the first production response to a suspected off-ratio condition?

21. Why should the mixed-material circuit normally be flushed before extended troubleshooting or shutdown?

22. Does turning off the proportioner guarantee that all fluid pressure has been relieved?

23. What is the best troubleshooting practice?

24. What provides the strongest support for final project acceptance?
