Daily Quiz (21)


What is one thing that some zinc-rich coatings and potassium silicate paints have in common?


True or false: A zinc silicate primer is classified as an organic zinc-rich coating.


True or false: Zinc dust is normally used in zinc-rich coatings.


Where would you be likely to find titanium zinc?


What mechanism of corrosion protection does zinc phosphate provide to coatings?


True or false: Zinc coatings are sometimes applied to structural concrete, such as bridge piers, to provide galvanic protection to rebar.


In SSPC’s Coating System Guide 12.00, Guide to Zinc-Rich Coating Systems, what type of untopcoated zinc-rich system is recommended for alkaline exposure, pH 10-12?


What is the name given to the zinc ammonium chloride solution that cleans and deposits a protective layer on steel before it is immersed in molten zinc to achieve galvanizing?


True or false: With zinc-rich coatings on steel, the zinc becomes the anode in a galvanic cell and sacrifices itself to protect the cathode, the underlying steel.


Cold galvanizing employs a coating with a high percentage by weight of what material?


True or False: A seal coat over thermal-sprayed zinc will perform better if application is delayed until at least 30 days have elapsed so that natural oxidation can form on the zinc.


True or False? To be effective, a seal coat over a thermal-sprayed zinc coating must be applied after a significant amount of natural oxidation has occurred.


True or false: Zinc phosphate pigments, when used in primers for steel substrates, provide sacrificial protection of the metal.


What is the main feature of zinc that allows it to provide cathodic protection to steel?


How are the zinc particles in a zinc-rich coating kept in suspension during spray application?


True or false: Thermal spraying of zinc is sometimes used for corrosion control on steel substrates.


Why are zinc-rich coatings sometimes applied to structural concrete?


True or false: If a zinc-rich coating has a silicate binder, it is classified as an organic zinc-rich.


In what way is a zinc-rich primer “rich?”


True or false: In multi-coat systems, it is not always the case that the higher the zinc loading in a zinc rich primer, the better the system performance will be.


True or false: Inorganic zinc pre-construction primers for shipbuilding normally have more zinc content than inorganic zinc primers applied after fabrication.
