Highly dispersible antimicrobial and adhesion agents

Abstract

Compositions of matter that have antimicrobial properties and adhesion properties and are highly dispersible in aqueous solutions. The presence of a large number of silanols on the molecules of this invention creates a solubility or disperseability of these molecules in aqueous solutions that is not obtainable from prior art antimicrobial monomers.
