Abstract
Described herein are clear coating antimicrobial compositions, methods of preparation, and uses thereof for conferring antimicrobial activity to a surface. One particular composition comprises at least one antimicrobial, a vinyl acetal derivative polymer binder and a solvent for solubilizing said at least one antimicrobial and said vinyl acetal derivative polymer binder. Another particular composition, comprises at least one antimicrobial and a binder polymer/solvent selected from an acrylic acid polymer, a polyester-based polymer, an epoxy-based polymer, and mixtures thereof.
Claims24
A clear coating antimicrobial composition for conferring antimicrobial activity to a hard surface, comprising:
- at least one antimicrobial, wherein said least one antimicrobial comprises at least one quaternary ammonium compound, and wherein the composition comprises more than 1% w/w quaternary ammonium compound;
- a vinyl acetal derivative polymer binder;
- an organic solvent for solubilizing said at least one antimicrobial and said vinyl acetal derivative polymer binder;
- and
- a carrier;
- wherein said composition provides durable antimicrobial activity once applied on a hard surface.
