Abstract

An antimicrobial coating composition is disclosed. The antimicrobial coating composition also includes a polymer having a plurality of alkene units and a plurality of macroCTA polymer units. The composition also includes one or more reactive silanes, one or more wetting agents, and one or more solvents. A method for applying an antimicrobial coating composition is disclosed. The method for applying an antimicrobial coating composition may include contacting a polymer, one or more wetting agents, one or more solvents, and one or more reactive silanes with one another to prepare an antimicrobial coating composition, homogenizing the antimicrobial coating composition, applying the antimicrobial coating composition to a substrate, and allowing the antimicrobial coating composition to dry at ambient conditions.

First claim

What is claimed is:

1. An antimicrobial coating composition, comprising:
a polymer comprising a plurality of alkene units and a plurality of macroCTA polymer units;
one or more reactive silanes;
one or more wetting agents; and
one or more solvents.

2. The antimicrobial coating composition of claim 1 , wherein the polymer is present in an amount of from about 0.05% to about 10% by total weight of the antimicrobial coating composition.

3. The antimicrobial coating composition of claim 1 , wherein the one or more reactive silanes are present in an amount of from about 0.1% to about 10% by total weight of the antimicrobial coating composition.

4. The antimicrobial coating composition of claim 1 , wherein the one or more reactive silanes comprises a glycidoxy functional group.

5. The antimicrobial coating composition of claim 4 , wherein the one or more reactive silanes comprises glycidoxypropyltrimethoxysilane.

6. The antimicrobial coating composition of claim 1 , wherein the one or more reactive silanes comprises an amine functional group.

7. The antimicrobial coating composition of claim 1 , wherein the one or more wetting agents comprise a surfactant, a co-solvent or a combination thereof.

8. The antimicrobial coating composition of claim 7 , wherein the antimicrobial coating composition further comprises a surfactant that is present in an amount of from about 0.1% to about 2% by total weight of the antimicrobial coating composition.

9. The antimicrobial coating composition of claim 7 , wherein the antimicrobial coating composition further comprises a co-solvent that is present in an amount of from about 0.5% to about 20% by total weight of the antimicrobial coating composition.

10. The antimicrobial coating composition of claim 1 , further comprising one or more catalysts.

11. The antimicrobial coating composition of claim 10 , wherein the one or more catalysts comprises acetic acid.

12. The antimicrobial coating composition of claim 10 , wherein the one or more catalysts comprises ammonium hydroxide.

13. The antimicrobial coating composition of claim 1 , further comprising one or more functional additives.

14. The antimicrobial coating composition of claim 13 , wherein the functional additive comprises a fluorescent marker.

15. The antimicrobial coating composition of claim 1 , wherein the solvent comprises water.

16. An antimicrobial coating composition, comprising:
a polymer comprising a plurality of alkene units and a plurality of macroCTA polymer units;
one or more reactive silanes comprising a glycidoxypropyltrimethoxysilane;
ammonium hydroxide;
one or more wetting agents; and
water.

17. A method for applying an antimicrobial coating composition, comprising contacting a polymer comprising a plurality of alkene units and a plurality of macroCTA polymer units, one or more wetting agents, one or more solvents, and one or more reactive silanes with one another to prepare an antimicrobial coating composition; homogenizing the antimicrobial coating composition to a substrate; and allowing the antimicrobial coating composition to dry at ambient conditions.

18. The method of claim 17 , further comprising pausing after homogenizing the antimicrobial coating composition to allow the antimicrobial coating composition time to pre-react in solution.

19. The method of claim 17 , wherein the substrate is metal, alloy, polymer, or combination thereof.

20. A method for applying the antimicrobial coating composition of claim 1 , the method comprising:
contacting the one or more solvents and the one or more reactive silanes with one another to prepare a first part of the antimicrobial coating composition;
contacting the one or more solvents, the polymer, and the one or more wetting agents with one another, to prepare a second part of the antimicrobial coating composition;
applying the first part of the antimicrobial coating composition to a substrate;
evaporating the one or more solvents from the first part of the antimicrobial coating composition; and
applying the second part of the antimicrobial coating composition over the first part of the antimicrobial coating composition.
