Enamel

Vitreous enamels are inorganic coatings that have high chemical and mechanical strentgh including food safe structure due to their glass-ceramic nature, where developed function crystals can be embedded in amorphous matrices.

These surfaces can be employed in high temperature, corrosion and abrasion resistant applications when they are required with expected engineering characteristics.

This coating can be applied on steel, copper, cast iron and aluminum alloy substrates with different application methods such as dipping, spraying, electrostatic spraying and electrophoretic enameling at 550 – 850 °C temperatures.

Vitreous enameling can be seen in all areas of our lives, from home appliances to industrial steel tanks and silos and this is mainly due to the excellent properties which can be gained from enameling, including, pH, chemical and temperature resistivity, improvements in strength properties and being completely physiologically and bacteriologically safe.
