An antimicrobial composition is formed from about 5 to about 25 wt % of an
antimicrobial formulation and about 75 to about 95 wt % of a silicone
resin. The antimicrobial formulation is formed from about 60 to about 95
wt % of an antimicrobial material, about 1 to about 30 wt % calcium
chelator, about 0.001 to about 0.25 wt % pigment, and about 0.5 to about
3.5 wt % lubricant. The silicone resin may be a dispersion of about 40 to
about 60 w/v % of an RTV silicone resin in a solvent, a liquid silicone
resin, or a solid silicone resin. An antimicrobial coating may be formed
on the surface of an article by applying an antimicrobial composition to
the article and permitting the solvent to evaporate. It may also be
formed by making a mixture of about 5 to about 12 wt % of an
antimicrobial formulation and about 88 to about 95 wt % of a liquid or
solid silicone resin and molding, overmolding, or extruding the article
from the compounded mixture.
