Abstract
Room temperature cure, antimicrobial coatings that demonstrate a balance of properties including low dissolution and good cohesion and adhesion are provided. Such coatings generally exhibit a greater zone of microbial inhibition, greater cohesion and a greater degree of adhesion to target surfaces when compared to high temperature cure, antimicrobial, hydrophilic coatings.
