Coatings

Functional coatings are thin coverings that can be used on crucibles to significantly improve performance, reduce impurities when melting and holding pure alloys. It also stops dross build up and makes clean up fast and easy.

Applications

Coatings can be used in aluminium applications, zinc distillation, precious metals and pure copper melting 

Preheating/First Use

The chemically bonded coatings do not impact or change in any way the installation or startup / heating procedures for the crucible in which it has been applied.
