Abstract
Antimicrobial coatings with anti-staining properties that exhibit broad range adhesion characteristics are provided. The coating compositions comprise a mixture of water-borne resins that can be crosslinked through use of a suitable crosslinking agent. The coating compositions can be used on a variety of substrates and are highly flexible, thereby permitting their use on flexible and stretchable materials. Testing has shown the coatings to exhibit excellent antimicrobial characteristics against a broad class of particularly virulent pathogens.
Claims23
An antimicrobial coating composition comprising:
- a water-based dispersion comprising—
- about 5 to about 40 weight percent of at least one acrylic polymer resin on a dry basis;
- about 20 to about 50 weight percent of at least one melamine polymer resin on a dry basis;
- about 0.5 to about 15 weight percent of at least one siloxane polymer resin on a dry basis;
- at least one antimicrobial agent comprising silver or silver ions dispersed within said dispersion;
- and
- at least one crosslinking agent capable of crosslinking at least one of said acrylic and melamine polymer resins.
