Abstract
A cooktop includes a base and an electrically conductive coating applied to the lower surface of the base. The coating is composed of a paint containing electrically conductive particles dispersed in a silicone or polyester-silicone or epoxy-silicone resin. The conductive particles are selected from the group consisting of multi-wall or single-wall carbon nanotubes, graphene, copper metallic particles, nickel metallic particles, or combinations thereof.
Claims10
A cooktop comprising:
- a base having an upper surface and a lower surface;
- an electric power supply for supplying an electrically conductive coating with electric current;
- and
- an electrically conductive coating applied to said lower surface and operationally connected to said electric power supply;
- wherein said coating consists of a paint containing electrically conductive particles, dispersed in a silicone or polyester-silicone or epoxy-silicone resin, wherein said conductive particles are selected from the group consisting of multi-wall carbon nanotubes, single-wall carbon nanotubes, graphene, copper metallic particles, nickel metallic particles, or combinations thereof;
- wherein when the coating is supplied with electric current, the coating is heated by the Joule effect and the upper surface of the base is heated by conduction.
A method for producing a cooktop comprising the step of applying to a lower surface of a glass-ceramic base a paint containing electrically conductive particles dispersed in a silicone or polyester-silicone or epoxy-silicone resin, wherein said conductive particles are selected from the group consisting of multi-wall carbon nanotubes, single-wall carbon nanotubes, graphene, copper metallic particles, nickel metallic particles, or combinations thereof.
A method of using a paint containing electrically conductive dispersed particles in a silicone or polyester-silicone or epoxy-silicone resin, wherein said conductive particles are selected from the group consisting of multi-wall carbon nanotubes, single-wall carbon nanotubes, graphene, copper metallic particles, nickel metallic particles, or combinations thereof;
- producing a total or partial coating of a lower surface of a base for a cooktop made of glass-ceramic.
