Abstract

This disclosure relates to personal grooming apparatus that include coatings on the surface thereof that incorporate static dissipative additives that reduce the static build-up in the hair of users as compared to conventional apparatus. Other aspects of the present disclosure relate to methods for producing such apparatus, and methods for grooming the hair of an individual.

Claims (11)

1. A personal grooming apparatus for grooming the hair of a user, the apparatus containing a substrate and a coating disposed on the substrate, the coating having a surface for contacting hair during grooming, the coating having a surface resistivity of less than about 1×10 13 ohms/square and comprising a structural component selected from a silicone-modified fluoropolymer base resin or ceramic material or mixtures thereof, the coating comprising a static dissipative additive dispersed throughout the structural component to reduce the surface resistivity of the coating, wherein the static dissipative additive is selected from the group consisting of aluminum, carbon particles and mixtures thereof.

2. The personal grooming apparatus as set forth in claim 1 wherein the coating comprises at least about 4 wt % aluminum.

3. The personal grooming apparatus as set forth in claim 1 wherein the coating comprises at least about 1 wt % carbon particles.

4. The personal grooming apparatus as set forth in claim 1 wherein the static dissipative additive is carbon particles and the carbon particles are selected from the group consisting of carbon black, carbon nanotubes and graphite.

5. The personal grooming apparatus as set forth in claim 1 wherein the coating comprises ceramic material and the ceramic material is selected from the group consisting of silica, alumina, zirconia, silicon carbide and mixtures thereof.

6. The personal grooming apparatus as set forth in claim 1 wherein the substrate comprises a polymer or a metal.

7. The personal grooming apparatus as set forth in claim 1 wherein the apparatus is selected from the group consisting of a hair straightener, hair curler, curling iron, hot roller, a device for securing hair, shaver, clipper, razor, friction-reducing strips or pads, brush and comb.

8. The personal grooming apparatus as set forth in claim 1 wherein the coating has a surface resistivity of less than about 1×10 10 ohms/square.

9. The personal grooming apparatus as set forth in claim 1 wherein the coating has a surface resistivity of at least about 1×10 3 ohms/square.

10. The personal grooming apparatus as set forth in claim 1 wherein the coating has a thickness of at least about 8 μm.

11. The personal grooming apparatus as set forth in claim 1 wherein the coating has an affinity for positive charging of at least about −100 nC/J.
