EXAM 2026 COMPREHENSIVE EXAM SCRIPT
WITH VERIFIED SOLUTIONS GRADED A+
◉ What are solvents? Answer: Substances that dissolve other
substances to form a solution.
◉ Why can solvents in coatings be harmful? Answer: Because they
can release VOCs into the air.
◉ What are some examples of solvents used in coatings? Answer:
Acetone, toluene, xylene, and ethyl acetate.
◉ What are three commonly used galvanic anodes for carbon steel?
Answer: Zinc, Aluminum, and Magnesium
◉ What is the effect of temperature on corrosion rate? Answer:
Decrease in temperature decreases corrosion rate.
◉ What is an electrolyte? Answer: A medium that carries ionic
current.
,◉ What is sacrificial coating? Answer: A type of coating that
becomes the anode of an electrochemical cell.
◉ What is the role of binders in coating? Answer: Binders form a
stable film that retains its properties.
◉ What is a barrier coating? Answer: A coating that interrupts the
electrolyte of an electrochemical cell.
◉ What are two environments most susceptible to corrosion?
Answer: Marine Environment, Chemical with High Humidity
Environment
◉ What is the direction of electron flow in an oxidation reaction?
Answer: From the anode to the cathode through the metallic path.
◉ What is the role of binders? Answer: Binders bonds pigments
together and adhere to surface.
◉ What are solvents? Answer: Solvents are liquids that dissolve the
solid resins.
,◉ What is the purpose of pigments? Answer: Pigments hide the
substrates, provide decorative color, and enhance desired
properties.
◉ What are additives? Answer: Additives are special purpose
ingredients used to enhance the performance.
◉ What are vehicles? Answer: Vehicles are the liquid portions of the
coating.
◉ What is corrosion? Answer: Deterioration of metal or alloy due to
electrochemical reaction.
◉ What is passivation? Answer: Layer of oxides on metal surface for
corrosion protection.
◉ Give an example of a metal that undergoes passivation. Answer:
Stainless steel
◉ What is an anode? Answer: The electrode where oxidation occurs.
◉ What is a cathode? Answer: The electrode where reduction
occurs.
, ◉ What is a metallic pathway? Answer: The conductive path for
electrons to flow.
◉ What are electrolytes? Answer: Substances that conduct
electricity when dissolved in water.
◉ What is the function of an electrolyte in corrosion? Answer:
Allows passage of ions in corrosion cell.
◉ What is the function of a metallic pathway in corrosion? Answer:
Allows flow of electrons in corrosion cell.
◉ What is the galvanic series? Answer: Listing of metals in order of
reactivity.
◉ What is the general rule of the galvanic series? Answer: Less noble
metal connected to a more noble metal will corrode preferentially.
◉ What is localized corrosion? Answer: Corrosion that occurs in
specific areas.
◉ What are the types of localized corrosion? Answer: Pitting and
crevice corrosion.
