Sigma Barrier™ Coating
This special galvanized coating is available on Mott's full range of painted steel
cabinetry, fume hoods, and miscellaneous components. It provides excellent moisture
and corrosion resistance in applications that involve high levels of wetness and
humidity. Sigma Barrier™ protects steel from rusting in wet environments by not only
forming a protective barrier between the steel and the environment, but also going
one step further than paint, to provide electrochemical protection of the steel.
