  • Patent number: 7008979
    Abstract: A coating composition is disclosed which comprises an aqueous polymeric matrix, a hydrophilic polymer, a colloidal metal oxide and a crosslinker. The coating composition when applied on medical devices is hydrophilic, shows improved lubricity, abrasion resistance and substrate adhesion on metallic or plastic substrates. The coating also shows improved water sheeting thus providing the coated substrates with anti-fog properties. The coating absorbs aqueous dye or stain solutions making the substrate suitable for printing.

  • Patent number: 6054504
    Abstract: The present invention relates to biostatic compositions, as well as coatings and methods for preparing biostatic articles using the same. The compositions contain a hydrophilic polymer possessing a functional group which covalently bonds to an amine, thiol, carboxyl, or hydroxyl active group of an antimicrobial agent. The functional group is capable of reacting with and covalently bonding to an antimicrobial agent without effectively reducing antimicrobial property of the antimicrobial agent below its capability of acting as a biostatic agent and without releasing the antimicrobial agent into a solution.
