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.

Why is localized corrosion concerning? - Answer✔Damage is concentrated and can lead to
structural failure.
What is general corrosion? - Answer✔Uniform loss of material over entire surface.
How does general corrosion affect the surface? - Answer✔Results in general thinning of
affected surface.
Is general corrosion easy to inspect? - Answer✔Yes, it is relatively easy to inspect.
Does general corrosion cause catastrophic failure? - Answer✔No, it does not cause catastrophic
failure.
What is inorganic convertible thermosetting? - Answer✔Coating that undergoes irreversible
chemical changes upon curing.
What is inorganic non-convertible thermoplastic? - Answer✔Coating that softens upon heating
and hardens upon cooling.
What are the primary components of a liquid applied coating? - Answer✔Pigments and Vehicle
(Resin or Binder and Solvent)
What is a sacrificial coating system? - Answer✔A coating system where a more active metal is
applied over a less active metal to act as an anode and protect the underlying metal.
Why is inorganic zinc commonly used as a sacrificial coating over mild steel? - Answer✔Zinc is
more active than steel, so it becomes the anode and protects the steel from corrosion.
What is the purpose of a barrier coating? - Answer✔To create a physical barrier between the
metal surface and the corrosive environment, preventing direct contact and corrosion.
What is an inhibitive coating? - Answer✔A coating that releases corrosion inhibitors to slow
down or prevent corrosion on the metal surface.
How does a sacrificial coating provide corrosion control? - Answer✔By using a more active
metal as the coating, it sacrificially corrodes instead of the underlying metal, protecting it from
corrosion.
What does a well-written coating specification provide? - Answer✔Clear understanding of
project expectations.
Where can an inspector find the procedure for mixing a specified coating? - Answer✔Product
data sheet (PDS).
What is a product data sheet (PDS)? - Answer✔Document from manufacturers with valuable
product information.

What information does a safety data sheet (SDS) provide? - Answer✔Chemical hazards and
safety precautions.
What does a specification document tell the contractor? - Answer✔What and where to do, not
how to do it.
What is a standard? - Answer✔Formal document providing guidance for technical procedures.
What is an Inspection Test Plan (ITP)? - Answer✔Quality control tool for ensuring specified
requirements are met.
What is surface temperature? - Answer✔Temperature of the surface being coated.
How does temperature affect solvents? - Answer✔Affects evaporation time and curing rates,
leading to defects.
What is the minimum and maximum surface temperature for coating? - Answer✔Minimum:
40°F (5°C), Maximum: 125°F (40°C).
What should be the substrate temperature for coating application? - Answer✔At least 3°C or
5°F above the dew point temperature.
What are the effects of high air temperature? - Answer✔Shorter pot life, shorter induction
time, and lower viscosity.
What are the effects of high air temperature? - Answer✔Longer cure time, reduced re-coat
window, potential re-rusting, and wrinkling of the coating.
What are the effects of low air temperature? - Answer✔Longer pot life, longer induction time,
and higher viscosity.
What are the effects of low air temperature? - Answer✔Amine blush (bloom) and adhesion
issues.
What is Relative Humidity (RH)? - Answer✔Amount of water vapor in the air compared to
maximum.
What is Saturation? - Answer✔When air contains maximum moisture and condensation forms.
How does high RH affect coating application? - Answer✔Causes solvent entrapment and
blistering.
What is the recommended RH to prevent moisture on the surface? - Answer✔Below 85%.
What is the recommended RH to prevent corrosion? - Answer✔Below 40%.
