Abstract

The present disclosure relates to a compound that has biocidal activity or is a precursor of a compound with biocidal activity. The compound comprises an N-halamine precursor, at least one quaternary ammonium and at least one coating-incorporation group (CIG). In some embodiments of the present disclosure, the compound may be incorporated into a coating formulation. The coating formulation comprises the compound and at least one further component. In some embodiments of the present disclosure, the CIG reacts with the further component of the coating formulation to incorporate the compound into the coating formulation. In some embodiments, the coating formulation comprises a polymer. In some embodiments, the CIG of the compound reacts with the further component to incorporate the compound into the polymer of the coating formulation. The coating formulation may be used to coat a substrate. The coated substrate may demonstrate biocidal activity or the potential for increased biocidal activity.

First claim

The invention claimed is:

1. A compound having a general formula that is:

wherein X − is Cl − , Br − , I − or PO 4 3− .

2. The compound of claim 1 , wherein the N-halamine precursor group is converted into an N-halamine by a halogenation reaction.

3. A coating formulation comprising:
(a) a compound with the general formula:

wherein X − is Cl − , Br − , I − or PO 4 3− ; and

(b) at least one further component that is a polymer or a component of a polymer-based system.

4. The coating formulation of claim 3 , wherein the at least one further component is selected from a group consisting of: an acetate polymer; a vinyl ester polymer; a vinyl acetate polymer; a vinyl acetate homopolymer; an acrylate polymer; a methacrylate polymer; a melamine polymer; a modified melamine polymer; a urethane polymer; a polyurethane polymer; an aliphatic urethane polymer; a polyester; a self-crosslinking polyester; an epoxide polymers; an epoxide-ester polymer; a fluoropolymers; a silicone polymer; a silicone-based polymer; a polyethylene; a polypropylene; a polyvinyl chloride polymer; a polyamide polymer; a polybutylene polymer; a poly(buta-1,3-diene) polymer; a polysulfone polymer and combinations thereof.

5. A substrate with at least one surface that is coated with the coating formulation of claim 3 .

6. The substrate of claim 5 , wherein the at least one surface is selected from a group consisting of: a textile surface, a metal surface, a metal alloy surface, a polymer surface, a ceramic surface, a glass surface and a wood surface.

7. The substrate of claim 6 , wherein the textile surface is selected from a group consisting of a natural textile, a synthetic textile and a combination thereof.
