Daily Quiz (49)


True or false: According to a study reported in JPCL, two-coat systems comprised of zinc-rich primers and high-build polyaspartic topcoats were markedly inferior in performance to three-coat systems comprised of zinc-rich primers, intermediate coats, and moisture-cured polyurethane topcoats on Virginia bridges after ten years of service.


Which of the following is bad advice about spraying zinc-rich coatings?

True or false: The cure of an inorganic zinc-rich coating can be determined definitively by the MEK rub test (ASTM D4752).


True or false: Based on a study of coatings for offshore platforms reported in JPCL, fluoropolymer topcoats replaced polyurethanes in an oil company’s specification.


In what country was the first large-scale application of zinc-rich coatings?


True or false: Inorganic zinc-rich coatings, left untopcoated, decrease in barrier protection over time.


True or false: An inorganic zinc-rich primer can be topcoated as soon as it is dry.

True or false: Inorganic zinc-rich primers should be topcoated as soon as they appear to be dry.


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


True or false: SSPC has a standard for a single-coat zinc-rich painting system.


True or false: The porosity of inorganic zinc-rich coatings increases over time after they are applied.


True or false: The MEK solvent rub test (ASTM D 4752) and the coin rub test are both used to provide an estimate of the cure of an inorganic zinc-rich coating.


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.


True or false: Zinc-rich coatings work extremely well in protecting steel substrates in predominantly wet, highly alkaline exposure environments.


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


What solvent is used in the solvent rub test for cure of inorganic zinc coatings?


What is the name of the contacting surfaces of joints in steel structures formed with the use of high-strength bolts?


True or false? A recent JPCL article explains that waterborne zinc-rich epoxy primers must be three-component materials.


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


True or false: Inorganic zinc-rich coatings are appropriate for use on slip-critical surfaces of steel joints.


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.


When can you safely topcoat an inorganic zinc rich coating?


True or false: Organic zinc-rich coatings are generally more tolerant of deficient surface preparation than inorganic zinc-rich coatings.


When spraying zinc rich coatings, why is it useful to have the spray pot or container positioned at or above the level of the work?

What special mixing equipment is required for zinc-rich paints?


True or false: The SSPC standards SSPC-Paint 20 and SSPC-Paint 29 contain both performance and composition requirements for zinc-rich coatings.


True or false: Organic zinc-rich coatings resist higher temperatures than inorganic zinc-rich coatings.


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


Which of the following is bad advice about spraying zinc-rich coatings.


True or false: Inorganic zinc-rich coatings, normally used as primers in multi-coat systems, have sometimes been used as single-coat systems on bridges and other structures.

Which of the coating types below are likely to be acceptable for use on faying surface of steel structures?


True or false: inorganic zinc-rich coatings, because of their somewhat porous nature, must be topcoated to be effective in preventing corrosion.
