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.

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.
