Daily Quiz (14)


True or false: Mixed metal oxide pigments produced at high temperatures are used to improve the corrosion resistance of coatings.


True or false: Anodized finishes have excellent corrosion resistance in coastal settings.


True or false: Wet-dry cyclic tests of a coating’s corrosion resistance, conducted in the laboratory, have the same correlation to field performance as steady-state salt spray (fog) corrosion tests, such as ASTM B117 and ISO 9227.


True or false: According to noted coating authorities, wet adhesion is not one of the primary criteria for good corrosion resistance.


True or false: Test kits that contain small containers of pre-weighed, unhydrated calcium chloride are used to determine the corrosion resistance of coatings applied over soluble salts on steel substrates.


What type of pigments can provide corrosion resistance, mildew and bacterial resistance, fire retardance and anti-fouling properties?


True or false: Calcium borosilicate has been used as an anti-corrosive pigment in protective coatings.


True or false: Inhibitive, platey or sacrificial pigments can be used in coatings on steel for corrosion prevention.


What generic coating type has been tested by the U.S. Naval Research Laboratory and shown to resist corrosion while at the same time improving ballistic protection of armored amphibious assault vehicles?


True or false: SSPC offers a specification for corrosion-resistant coatings on carbon steel components of windows and doors.


True or false: Zinc-rich coatings protect steel mainly by inhibiting corrosion.


Pascal Verbiest, in his recent JPCL article, “Developments in Zinc Primers for Corrosion Protection,” describes four mechanisms of corrosion resistance provided by zinc primers.


True or False: Polysiloxanes are claimed by some supplier companies to be effective as part of a two-coat system for protecting steel from corrosion and providing durable UV resistance.


A high-strength, low-alloy steel that provides greater resistance to deterioration from atmospheric corrosion than conventional carbon steel has what generic name?
