  • Methods for diluting water-stabilized antimicrobial organosilane compositions
    Patent number: 7851459
    Abstract: The present invention relates to methods for diluting water-stable organosilane compositions comprising an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water. The organosilane composition is diluted with a glycol ether. The resultant diluted organosilane composition may be used to antimicrobially treat a substrate.

  • Water-Stabilized Antimicrobial Organosilane Compositions, and Methods for Using the Same
    Publication number: 20090074971
    Abstract: The present invention relates to water-stable compositions formed by mixing an organosilane, optionally having a non-hydrolyzable organic group, but having one or more hydrolyzable groups, and an acidified stabilizing solution prepared from at least one acid, and at least one cationic surfactant, preferably at least one quaternary ammonium salt (QAS), in water. The composition does not comprise glycol ether. The present invention also relates to methods of treating a substrate by mixing or contacting the substrate with the composition of this invention for a period of time sufficient for treatment of the substrate, methods of antimicrobially treating a food article, methods of antimicrobially coating a fluid container, methods of dyeing and treating a substrate, and methods of antimicrobially coating a latex medical article. The invention also pertains to a treated substrate comprising the composition of this invention.
