Theory CBT
What are Volatile Organic Compounds (VOCs)? - CORRECT ANSWER
Chemicals that easily evaporate at room temperature.
What are solvents? - CORRECT ANSWER Substances that dissolve
other substances to form a solution.
Why can solvents in coatings be harmful? - CORRECT ANSWER
Because they can release VOCs into the air.
What are some examples of solvents used in coatings? - CORRECT
ANSWER Acetone, toluene, xylene, and ethyl acetate.
What are three commonly used galvanic anodes for carbon steel? -
CORRECT ANSWER Zinc, Aluminum, and Magnesium
What is the effect of temperature on corrosion rate? - CORRECT
ANSWER Decrease in temperature decreases corrosion rate.
What is an electrolyte? - CORRECT ANSWER A medium that carries
ionic current.

What is sacrificial coating? - CORRECT ANSWER A type of coating
that becomes the anode of an electrochemical cell.
What is the role of binders in coating? - CORRECT ANSWER Binders
form a stable film that retains its properties.
What is a barrier coating? - CORRECT ANSWER A coating that
interrupts the electrolyte of an electrochemical cell.
What are two environments most susceptible to corrosion? - CORRECT
ANSWER Marine Environment, Chemical with High Humidity
Environment
What is the direction of electron flow in an oxidation reaction? -
CORRECT ANSWER From the anode to the cathode through the metallic
path.
What is the role of binders? - CORRECT ANSWER Binders bonds
pigments together and adhere to surface.
What are solvents? - CORRECT ANSWER Solvents are liquids that
dissolve the solid resins.

What is the purpose of pigments? - CORRECT ANSWER Pigments hide
the substrates, provide decorative color, and enhance desired properties.
What are additives? - CORRECT ANSWER Additives are special
purpose ingredients used to enhance the performance.
What are vehicles? - CORRECT ANSWER Vehicles are the liquid
portions of the coating.
What is corrosion? - CORRECT ANSWER Deterioration of metal or
alloy due to electrochemical reaction.
What is passivation? - CORRECT ANSWER Layer of oxides on metal
surface for corrosion protection.
Give an example of a metal that undergoes passivation. - CORRECT
ANSWER Stainless steel
What is an anode? - CORRECT ANSWER The electrode where
oxidation occurs.
What is a cathode? - CORRECT ANSWER The electrode where
reduction occurs.

What is a metallic pathway? - CORRECT ANSWER The conductive
path for electrons to flow.
What are electrolytes? - CORRECT ANSWER Substances that conduct
electricity when dissolved in water.
What is the function of an electrolyte in corrosion? - CORRECT
ANSWER Allows passage of ions in corrosion cell.
What is the function of a metallic pathway in corrosion? - CORRECT
ANSWER Allows flow of electrons in corrosion cell.
What is the galvanic series? - CORRECT ANSWER Listing of metals in
order of reactivity.
What is the general rule of the galvanic series? - CORRECT ANSWER
Less noble metal connected to a more noble metal will corrode
preferentially.
What is localized corrosion? - CORRECT ANSWER Corrosion that
occurs in specific areas.
What are the types of localized corrosion? - CORRECT ANSWER
Pitting and crevice corrosion.
