Antimicrobial floor coatings and formulations

Abstract

An antimicrobial floor coating is provided comprising: a matrix comprising a polymeric material; and a plurality of second phase particles comprising a controlled release agent comprising a plurality of antimicrobial copper ions. Polymeric materials include epoxies and acrylics, and the plurality of second phase particles are distributed within the matrix. Further, the outer surface of the coating exhibits at least a 2 log reduction in the concentration of Staphylococcus aureus according to the modified EPA copper test protocol. Further, the controlled release agent may comprise phase separable glass.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of priority under 35 U.S.C. §119 to U.S. Provisional Application Serial No. 62 / 579,931, filed November 1, 2017, the contents of which are based upon and incorporated by reference in its entirety. Background technique [0003] The present disclosure generally relates to antimicrobial floor coatings and formulations. More specifically, various embodiments described herein relate to antimicrobial floor coatings and formulations having polymeric materials and antimicrobial copper ions. [0004] Floor coatings and varnishes are important to the aesthetics and wear resistance of the underlying concrete, wood and other floor coverings. These floor coatings and lacquers may be susceptible to contamination by microorganisms (eg, bacteria, fungi, viruses, etc.), especially when compared to coatings and lacquers used on other surfaces (eg, walls). However, floor coatings and lacquers also need ...
