First Claim
Patent Images
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×
- 1013 ohms/square and comprising a structural component selected from a base resin, ceramic material and mixtures thereof, the coating comprising a static dissipative additive dispersed throughout the structural component to reduce the surface resistivity of the coating.

16. A method for enhancing the static dissipative effect of a substrate of a personal grooming apparatus that is used to groom hair, the method comprising:
-
applying a coating composition to the substrate of the apparatus, the coating composition comprising a structural component selected from a base resin, ceramic material and mixtures thereof, the coating composition comprising a static dissipative additive dispersed throughout the structural component; and heating the coated substrate to vaporize the solvent and form a coating, wherein the coating has a surface resistivity of less than about 1×
1013 ohms/square. - View Dependent Claims (17, 18, 19, 20, 21, 22, 23, 24)
