Porcelain Enamel Coatings

Porcelain enamel is an inorganic-type coating, which is applied to metals or glass for both decorative and functional purposes.

This coating is a silica-based solidified glass mass obtained by high-temperature firing (temperature can range between 450 and 1200 °C depending on the substrate).

Porcelain enamel coatings differ from ceramic coatings mainly by their glass structure and dilatation coefficient, and from organic paints mainly by the inorganic nature of the matrix and the chemical bond that exists between the coating and the substrate.
