Henze boron nitride coatings are used as highly effective release agents in the casting of light alloys.
They are particularly well suited to coating refractory materials and ceramic components, such as runners, nozzles, plugs and thermocouple protection tubes.
HeBoCoat® boron nitride coatings are also successfully applied to enhance the metallic surfaces of casting and ingot moulds, ladles and other tools to prevent the formation of unwanted, bake-on melt deposits.
Boron nitride has a high chemical resistance with respect to the vast majority of molten metals, such as aluminium, magnesium or steel alloys which, when combined with the excellent adhesion properties of the HeBoCoat® coating to the treated substrate, results in an excellent service life of the protected working surface.
These advantageous properties are also exploited in HeBoSint® boron nitride sintered parts such as nozzles and crucibles such as in the metal spraying of powder.
