Name:
Porcelain Enamel
Detailed information:
A substantially vitreous inorganic coating bonded to metal by fusion above 426C (ASTM). Composed of various blends of low-sodium frit, clay, feldspar, and other silicates; ground in a ball mill; and sprayed onto a metal surface (steel, iron, or aluminum), to which it bonds firmly after firing, giving a glasslike fire-polished surface.

Properties:

High hardness, abrasion, and chemical resistance except to hydrogen fluoride and hot strong caustic; low expansion coefficient. Corrosion resistant, stable to heat-shock, easy to clean and decontaminate.

Use:

Chemical reaction equipment, light reflectors, laboratory bench tops, storage tanks and containers, high temperature process equipment, seawater treatment and marine engine parts, glazing frit.
