A coating material for coating glass or glass ceramics, comprising a sol-gel coating system which includes particles of a chain-like morphology and pigments.
A coating material for coating glass or glass ceramics, comprising in mass percent:
- sol-gel hydrolysate from 14 to 25%;
- inorganic particles having a chain-like and/or fibrous morphology from 11 to 20%;
- inorganic pigments from 18 to 44%;
- and
- solvents from 23 to 45%.
A composite material, comprising:
- a glass or glass ceramic substrate, and
- a coating material comprising in mass percent:
- a crosslinked sol-gel hydrolysate from 22 to 38%;
- and
- inorganic particles from 18 to 31%, the inorganic particles having a morphology selected from the group consisting of chain-like, fibrous, and combinations thereof.
A composite material comprising a glass or glass ceramic substrate and a baked coating material comprising, in mass percent, from 30 to 55% of transparent semi-metal or metal oxides and from 45 to 70% of inorganic pigments.
