1. SCOPE 1.1 This standard applies to a high-build two-component epoxy coating¹ that is
self-priming and low-temperature curing for the protection of clean steel or
concrete surfaces exposed to severely corrosive conditions. 1.2 This coating is intended for use as a protective coating on interior and
exterior substrates exposed to fresh or sea water immersion, tidal and splash
zones, high humidity, condensation, soil burial, brine, alkalies, chemical
fumes and chemical splashings by moderately strong sulfuric and muriatic acids.
Although this coating is suitable for exterior use, chalking will occur upon
weathering. Durability can be improved by applying other finishes suitable for
the intended end use. This coating is most suited to application by airless
spray. Small areas may be coated with a brush or roller. 1.3 This coating is mainly intended for use on steel surfaces and suitably
treated galvanized steel and aluminum. However, it may also be used on wood,
masonry and concrete surfaces. Primers are not required in normal usage, but
if conditions dictate, the manufacturer's advice regarding a suitable primer
shall be obtained. 1.4 The testing and evaluation of a product against this standard may require
the use of materials and/or equipment that could be hazardous. This document
does not purport to address all the safety aspects associated with its use.
Anyone using this standard has the responsibility to consult the appropriate
authorities and to establish appropriate health and safety practices in
conjunction with any applicable regulatory requirements prior to its use. ¹ Unreacted volatile polyamine curing agents having a boiling point lower than
300°C are not permitted in coatings complying with this standard.
