Abstract
The invention relates to a novel method of enameling substrates comprised of glass or vitroceramic material, according to which method the enamel composition contains graphite as a component, with the aim of improving the mechanical properties of the enameled substrate and/or conferring anti-adhesive properties on the composition. The invention also relates to the composition, and the enameled substrates obtained.
Claims26
A method of improving the mechanical properties of an enameled substrate, and/or conferring anti-adhesive properties on an enamel composition, said method comprising enameling a glass substrate by coating an enamel composition comprising graphite as a component thereof on at least a part of the surface of the substrate, and subsequently fusing or vitrifying the enamel coating.
An enameled glass substrate comprising:
- a glass substrate;
- and,
- an enamel composition coated on said substrate, wherein said enamel composition comprises:
- graphite;
- a powder comprising a glass frit and at least one pigment;
- and
- a medium.
An enamel composition, comprising:
- graphite;
- a powder;
- and
- a medium,
- wherein said powder comprises a glass frit and at least one pigment.
A process for enameling glass substrates, comprising the steps of:
- depositing an enamel composition on a substrate;
- and
- heat-treating or firing,
- wherein said substrate comprises a glass material;
- and
- wherein said enamel composition comprises graphite.
An enameled glass substrate prepared by a process comprising the steps of:
- depositing an enamel composition comprising graphite on a substrate comprising a glass material;
- and
- heat-treating or firing said substrate.
