1. The primary purpose of a protective coating is to:
A. Enhance aesthetic appearance
B. Increase surface roughness
C. Prevent corrosion or deterioration
D. Improve thermal conductivity
Rationale: Protective coatings act as barriers preventing corrosion,
oxidation, or chemical attack on substrates.
2. The most common cause of coating failure is:
A. Wrong pigment ratio
B. High humidity during storage
C. Improper surface preparation
D. Excessive film thickness
Rationale: Poor surface preparation leads to inadequate adhesion, the
leading cause of premature coating failure.
3. Which standard defines surface cleanliness for abrasive blast cleaning?
A. SSPC-SP8
B. SSPC-SP10
C. SSPC-SP5/NACE No.1
D. ASTM D4417
, Rationale: SSPC-SP5/NACE No.1 specifies “White Metal Blast Cleaning,”
the highest level of surface cleanliness.
4. The term “DFT” stands for:
A. Dry Finish Time
B. Ductile Film Texture
C. Dry Film Thickness
D. Dynamic Film Transfer
Rationale: DFT measures the final coating thickness after curing, critical
for performance.
5. Which environmental condition most affects coating application?
A. UV exposure
B. Wind velocity
C. Relative humidity and dew point
D. Sound vibration
Rationale: Exceeding dew point or humidity limits can cause
condensation and poor adhesion.
6. The most appropriate surface preparation method for heavily rusted
steel is:
A. Power tool cleaning
B. Solvent wipe
C. Abrasive blast cleaning
D. Water rinse
Rationale: Abrasive blasting effectively removes heavy rust and mill
scale, ensuring a clean substrate.
7. Which coating system provides cathodic protection?
A. Vinyl
B. Epoxy
C. Zinc-rich primer
D. Alkyd
Rationale: Zinc-rich primers act sacrificially to protect steel cathodically.
8. The purpose of a primer in a multi-coat system is to:
A. Provide color
B. Reduce gloss
, C. Promote adhesion and corrosion protection
D. Seal pores
Rationale: Primers ensure adhesion between substrate and subsequent
coats, preventing corrosion.
9. Which test determines coating adhesion?
A. Holiday detection
B. Gloss measurement
C. Pull-off test (ASTM D4541)
D. Pencil hardness test
Rationale: The pull-off test measures the force required to detach
coating from the substrate.
10.A coating’s “pot life” refers to:
A. Storage duration
B. Time to cure
C. Usable time after mixing
D. Shelf life
Rationale: Pot life is the period a mixed coating remains applicable
before gelling.
11.The main binder in epoxy coatings is:
A. Alkyd resin
B. Acrylic polymer
C. Epoxide resin and amine hardener
D. Urethane
Rationale: Epoxy coatings cure via a chemical reaction between epoxide
resin and hardener.
12.The most suitable coating for high chemical resistance is:
A. Alkyd
B. Vinyl
C. Epoxy or polyurethane
D. Acrylic
Rationale: Epoxies and polyurethanes resist acids, alkalis, and solvents
effectively.
