INSPECTOR THEORY QUE STIONS AND
ANSWERS
Question : What are Volatile Organic Compounds (VOCs)?
CORRECT ANSWER: Chemicals that easily evaporate at
room temperature.
Question : What are solvents?
CORRECT ANSWER: Substances that dissolve other
substances to form a solution.
Question : Why can solvents in coatings be harmful?
CORRECT ANSWER: Because they can release VOCs into
the air.
Question : What are some examples of solvents used in
coatings?
CORRECT ANSWER: Acetone, toluene, xylene, and ethyl
acetate.
Question : What are three commonly used galvanic anodes
for carbon steel?
CORRECT ANSWER: Zinc, Aluminum, and Magnesium
Question : What is the effect of temperature on corrosion
rate?
CORRECT ANSWER: Decrease in temperature decreases
corrosion rate.
Question : What is an electrolyte?
CORRECT ANSWER: A medium that carries ionic current.
Question : What is sacrificial coating?
CORRECT ANSWER: A type of coating that becomes the
anode of an electrochemical cell.
Question : What is the role of binders in coating?
CORRECT ANSWER: Binders form a stable film that
retains its properties.
Question : What is a barrier coating?
CORRECT ANSWER: A coating that interrupts the
electrolyte of an electrochemical cell.
Question : What are two environments most susceptible to
corrosion?
CORRECT ANSWER: Marine Environment, Chemical
with High Humidity Environment
Question : What is the direction of electron flow in an
oxidation reaction?
CORRECT ANSWER: From the anode to the cathode
through the metallic path.
Question : What is the role of binders?
CORRECT ANSWER: Binders bonds pigments together
and adhere to surface.
Question : What are solvents?
CORRECT ANSWER: Solvents are liquids that dissolve
the solid resins.
Question : What is the purpose of pigments?
CORRECT ANSWER: Pigments hide the substrates,
provide decorative color, and enhance desired properties.
Question : What are additives?
CORRECT ANSWER: Additives are special purpose
ingredients used to enhance the performance.
Question : What are vehicles?
CORRECT ANSWER: Vehicles are the liquid portions of
the coating.
Question : What is corrosion?
CORRECT ANSWER: Deterioration of metal or alloy due
to electrochemical reaction.
Question : What is passivation?
CORRECT ANSWER: Layer of oxides on metal surface
for corrosion protection.
Question : Give an example of a metal that undergoes
passivation.
CORRECT ANSWER: Stainless steel
Question : What is an anode?
CORRECT ANSWER: The electrode where oxidation
occurs.
Question : What is a cathode?
CORRECT ANSWER: The electrode where reduction
occurs.
Question : What is a metallic pathway?
CORRECT ANSWER: The conductive path for electrons to
flow.
Question : What are electrolytes?
CORRECT ANSWER: Substances that conduct electricity
when dissolved in water.
