Patent ID: 7405006

Claim:
A method of forming a thin coating of interpenetrating polysiloxane with organic moieties predominantly oriented toward the exposed surface of said coating to produce a permanent positive surface potential of said coating onto a substrate rendering the surface bio-static, self-sterilizing, or remediable, said method comprising the steps of: A. providing a reactive silanol as an aqueous or non-aqueous dispersion of a partial condensate of monomethyl or monethyl silanol by hydrolyzing monomethyl or monethyl alkoxysilane; B. dispersing said reactive silanol in an alcohol or water or both to form an admixture; C. applying said admixture to the substrate; D. allowing said admixture to cure and harden into an interpenetrating polysiloxane with organic moieties predominantly oriented toward said exposed surface forming a permanent positive surface potential of said coating to produce the bio-static, self-sterilizing and remediable said exposed surface; and E. further curing said coating by applying a hardener composed of water or acidified water and epoxy or amino silanes, said hardener being applied by mechanical polishing at ambient temperatures wherein a hard, low porosity interpenetrating network of organosolixanes with organic moieties oriented toward the surface is formed atop the substrate.
