Antimicrobial floor coatings and formulations

Abstract

An antimicrobial floor coating is provided that includes a matrix comprising a polymeric material; and a plurality of second phase particles comprising a controlled release agent, the controlled release agent comprising a plurality of antimicrobial copper ions. The polymeric material comprises an epoxy and an acrylic, and the plurality of second phase particles is distributed within the matrix. Further, an exterior surface of the coating exhibits at least a 2 log reduction in a concentration of Staphylococcus aureus under a Modified EPA Copper Test Protocol. Further, the controlled release agent can comprise a 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 ...
