Abstract:
A method of preparing an antimicrobial coating comprises coating a surface with an aqueous mixture of 3-(trihydroxysilyl)propyl dimethyloctadecyl ammonium chloride, 3-chloropropyltrimethoxysilane, and triethanolamine and then coating the surface with an aqueous titanyl sol-gel solution comprising an aqueous mixture of peroxotitanium acid and peroxo-modified anatase sol overtop of the silane to form the antimicrobial coating. The antimicrobial coating exhibits residual antimicrobial efficacy against  E. coli  and  S. epidermidis  after water rinsing or after abrasion. The use of 3-chloropropyltrimethoxysilane was found to improve storage stability of the quaternary silane composition and the durability of the antimicrobial coating.

Claim (Index 16):
A method of preparing an antimicrobial coating on a portion of a surface, the method comprising:\n spray coating an aqueous antimicrobial coating composition comprising about 0.75 wt. % 3-(trihydroxysilyl)propyl dimethyloctadecyl ammonium chloride, about 0.12 wt. % 3-chloropropyltrimethoxysilane, and about 0.045 wt. % triethanolamine, remainder water, on the portion of the surface; allowing the aqueous antimicrobial coating composition to visibly dry on the portion of the surface; disposing an aqueous titanyl sol-gel comprising about 0.85 wt. % of a mixture of peroxotitanium acid and peroxo-modified anatase sol in water on the portion of the surface overtop of the dried aqueous antimicrobial coating composition; and allowing the aqueous sol-gel to dry to provide the antimicrobial coating.
