Abstract
Disclosed is an antimicrobial coating and antimicrobial laminate that can be used on surfaces to prevent the spread of bacteria and viruses. Spray-on techniques can be used with antimicrobial agents mixed with an air-drying antimicrobial coating and a heated liquid plastic antimicrobial coating. Efficacy of the antimicrobial coating can be monitored by detecting changes in texture, color, opaqueness, fluorescence, and other techniques. Soft plastics and acrylics can be used to suspend the antimicrobial agents to provide better efficacy in the release of antimicrobial agents over time.
Claims42
An antimicrobial plastic laminate comprising:
- an antimicrobial plastic layer having a hardness of less than 50 Shore A or a durability of Class 2, Class 3 or Class 4 according to DIN EN 13300, said antimicrobial layer comprising antimicrobial particles and opaque particles mixed in said antimicrobial plastic layer;
- a substrate material having a first surface that is attached to said antimicrobial plastic layer;
- an adhesive disposed on a second surface of said substrate that allows attachment of said antimicrobial plastic laminate to a surface to be protected.
A method of making an antimicrobial laminate comprising:
- mixing antimicrobial particles in a liquid plastic medium having a hardness of less than 50 Shore A or a durability of Class 2, Class 3 or Class 4 according to DIN EN 13300, together with particles that render said liquid plastic medium opaque to form an opaque, antimicrobial liquid plastic mixture;
- forming an opaque, antimicrobial solid layer on a first side of a substrate from said opaque, antimicrobial liquid plastic mixture;
- placing an adhesive on said second side of said substrate.
An antimicrobial plastic laminate comprising:
- a substrate material having a first surface and a second surface;
- an antimicrobial plastic layer having a hardness of less than 50 Shore A or a durability of Class 2, Class 3 or Class 4 according to DIN EN 13300, said antimicrobial plastic layer comprising antimicrobial particles mixed in said antimicrobial plastic layer, said antimicrobial plastic layer having a first surface disposed on said first surface of said substrate and having a second textured surface that is exposed to users that touch said antimicrobial plastic laminate so that said users can detect wear of said antimicrobial plastic layer where said texture is worn;
- an adhesive disposed on said second surface of said substrate for attachment of said antimicrobial laminate to a surface to be protected.
An antimicrobial spray coating for covering a surface to be protected from spreading microbes comprising:
- a liquid plastic medium that solidifies when sprayed on said surface to create a solid plastic coating on said surface having a hardness of less than 50 Shore A or a durability of Class 2, Class 3 or Class 4 according to DIN EN 13300;
- antimicrobial particles mixed in said liquid plastic medium;
- texture particles mixed in said liquid plastic medium that provide a tactile indication of the amount of wear of said plastic coating.
An antimicrobial spray coating for covering a surface to protect against the spreading of microbes on said surface comprising:
- a liquid plastic medium that solidifies when sprayed on said surface to create a plastic coating on said surface having a hardness of less than 50 Shore A or a durability of Class 2, Class 3 or Class 4 according to DIN EN 13300;
- antimicrobial particles mixed in said plastic medium that kill microbes on contact;
- opaque particles mixed in said plastic medium that make said plastic coating non-transparent so that said surface is visible in areas where said plastic coating is worn.
A method of protecting a surface from spreading microbes comprising:
- mixing antimicrobial particles and opaque particles in a liquid plastic medium;
- spraying said liquid plastic medium on a surface to impede transfer of microbes from said surface and cover said surface with opaque particles;
- allowing said liquid plastic medium to solidify on said surface as a non-transparent solid antimicrobial plastic having a hardness of less than 50 Shore A or a durability of Class 2, Class 3 or Class 4 according to DIN EN 13300.
