1. What is the primary purpose of a protective coating?
A. To improve aesthetics
B. To reduce surface friction
C. To protect a substrate from environmental degradation
D. To make cleaning easier
Correct Answer: C
Rationale: Protective coatings are designed to prevent
corrosion, abrasion, and environmental damage.
2. Which type of coating provides the best barrier against
moisture and chemicals?
A. Epoxy
B. Acrylic
C. Alkyd
D. Latex
Correct Answer: A
Rationale: Epoxies have excellent chemical resistance and low
permeability.
3. What does SSPC stand for?
A. Standard Steel Protection Code
B. Society for Surface Preparation and Coating
,C. Society for Protective Coatings
D. Surface Science and Protection Council
Correct Answer: C
Rationale: SSPC is a professional organization for coatings
standards.
4. Which surface profile measurement tool is commonly used
in coatings work?
A. Micrometer
B. Dry film thickness gauge
C. Surface profile replica tape
D. Vernier caliper
Correct Answer: C
Rationale: Replica tape measures surface roughness/profile
created for coating adhesion.
5. What is “flash rusting”?
A. Spontaneous ignition of coating
B. Rapid corrosion occurring after surface preparation
C. Excessive gloss development
D. Paint blistering
Correct Answer: B
Rationale: Flash rust is early oxidation of freshly prepared steel
before coating.
6. What environmental condition greatly affects coating
performance?
,A. Ambient temperature
B. Sound levels
C. Wind direction
D. Magnetic field
Correct Answer: A
Rationale: Temperature influences curing rates and film
formation.
7. Which coating defect is caused by trapped solvent?
A. Orange peel
B. Blistering
C. Cratering
D. Sagging
Correct Answer: B
Rationale: Solvent trapped under the film can vaporize and
blister.
8. What is the purpose of a primer?
A. To enhance topcoat color
B. To provide initial adhesion and corrosion protection
C. To reduce drying time
D. To increase gloss
Correct Answer: B
Rationale: Primers improve adhesion and often provide
corrosion resistance.
9. What is the main advantage of plural component coatings?
, A. Lower cost
B. Faster dry time and improved performance
C. Easier application
D. Less surface prep required
Correct Answer: B
Rationale: Multi-component systems cure chemically for
superior properties.
10. Which solvent property is most important for coating
drying?
A. Color
B. Volatility
C. Refractive index
D. Odor
Correct Answer: B
Rationale: Higher volatility solvents evaporate faster, affecting
dry time.
11. Surface preparation standards ensure what?
A. Uniform gloss
B. Clean, roughened surface for adhesion
C. Faster application
D. Reduced coating thickness
Correct Answer: B
Rationale: Proper prep removes contamination and creates
profile.
12. What does “DFT” stand for?
