Antimicrobial-treated steel has been developed for use in
refrigeration systems, HVAC systems, appliances and building components where
growth of bacteria, mold and mildew may be an issue.
Mapes & Sprowl Steel, Elk Grove Village, Ill., through a
partnership with AK Coatings, Middleton, Ohio, offers the AgIon coating, which
is an inorganic compound whose active ingredient is ionic silver. Encapsulated
in a zeolite matrix for continuous controlled release to the surface of the
treated steel, silver ions suppress the growth of destructive bacteria and
other microbes. The material is incorporated into an epoxy-based paint and
applied to steel using roll-coating technology.
The AgIon coating has been formulated in a way that allows
the material to be fabricated in the same manner as non-AgIon treated steels
without loss of coating or efficacy, according to Mapes & Sprowl. On
treated-steel articles, the pieces may be welded because the surface coating
can be repaired. Touchup paint for AgIon-treated products is available.
