SOLUTIONS GUARANTEE A+
✔✔What is passivation? - ✔✔A layer of oxides formed on the surface of a metal that
provides corrosion protection.
✔✔Give an example of a metal that undergoes passivation. - ✔✔stainless steel
✔✔What is an anode? - ✔✔the electrode at which oxidation occurs
✔✔What is a cathode? - ✔✔the electrode at which reduction occurs
✔✔What are electrolytes? - ✔✔Substances that conduct electricity when dissolved in
water.
✔✔What is the recommended RH to prevent moisture on the surface? - ✔✔below 85%
✔✔What is the recommended RH to prevent corrosion? - ✔✔below 40%
✔✔What is SSPC-VIS 1? - ✔✔Dry Abrasive Blasting.
✔✔What is an inhibitive coating? - ✔✔A coating that releases corrosion inhibitors to
slow down or prevent corrosion on the metal surface.
✔✔How does a sacrificial coating provide corrosion control? - ✔✔By using a more
active metal as the coating, it sacrificially corrodes instead of the underlying metal,
protecting it from corrosion.
✔✔What is the purpose of a barrier coating? - ✔✔To create a physical barrier between
the metal surface and the corrosive environment, preventing direct contact and
corrosion.
✔✔Why is inorganic zinc commonly used as a sacrificial coating over mild steel? -
✔✔Zinc is more active than steel, so it becomes the anode and protects the steel from
corrosion.
✔✔What are the causes of dry spray? - ✔✔Rapid solvent evaporation, high air
pressure, or wind.
✔✔How does low surface temperature affect curing? - ✔✔It slows down curing and
affects the re-coat window.
✔✔What is flash rusting? - ✔✔Rusting caused by high humidity or low surface
temperatures.
, ✔✔What is SSPC-SP 17? - ✔✔Thorough Abrasive Blast Cleaning of Non-Ferrous
Metals or Stainless Steel.
✔✔What is the minimum and maximum surface temperature for coating? -
✔✔Minimum: 40°F (5°C), Maximum: 125°F (40°C).
✔✔How does high air temperature affect mixing and thinning paint? - ✔✔It reduces
induction time, pot life, and re-coat window.
✔✔What is surface profile also referred to as? - ✔✔Anchor profile.
✔✔What is SSPC-SP 16? - ✔✔Brush-Off Blast Cleaning of Coated and Uncoated
Galvanized Steel, Stainless Steels, and Non-Ferrous Metals
✔✔What is an advantage of using grit abrasive for blasting? - ✔✔Simultaneous creation
of angular surface profile suitable for adhesion.
✔✔What are some examples of oil-based coatings? - ✔✔Alkyds or epoxy esters.
✔✔What is an epoxy ester? - ✔✔An alkyd coating with a small amount of epoxy resin
added.
✔✔What is stripe coating? - ✔✔The application (by brush or spray) of an extra coat of
paint to edges, welds, fasteners, corners, and other irregular areas, before or after a full
coat is applied.
✔✔What is NACE SP0178? - ✔✔Standard for tanks and vessels lined for immersion
services.
✔✔What is NACE SP508? - ✔✔Methods of validating equivalence to ISO 8502-9 on
measurements of soluble salts.
✔✔What is allowed for NACE No. 3/SSPC-SP 6? - ✔✔Random staining limited to no
more than 33% of each unit area of surface (9 square inch). May consist of light
shadows, slight streaks or minor discolorations caused by stains of mill scale or stains
of previously applied coating.
✔✔What is allowed for NACE No. 2/SSPC-SP 10? - ✔✔Random staining limited to no
more than 5% of each unit area of surface (9 square inch). May consist of light
shadows, slight streaks or minor discolorations caused by stains of mill scale or stains
of previously applied coating.
