Boron nitride coating UNICHIM-BNC
UNICHIM-BNC is an inorganic boron nitride based coating which provides an outstanding protection, release (non-stick) and lubrication performance while high-temperature processes. The coating is suitable for brushing and spraying. For the best results and to avoid cracks the coating can be diluted with water till proper consistency (basically 1:5).
The coating is non-wetted and inert to most of molten metals, slags and drosses (aluminum, magnesium, zinc, etc.); can be applied at high temperatures – up 900 °C in air, 1400 °C in reducing atmosphere; perfectly suited for aluminum, magnesium and zinc casting process - protective covering of all liquid metal transfer system components: launders, runners, filter bowls, boxes, caster tips, dross press heads, etc.
Advantages
- Excellent release and lubrication properties
- Reduce corrosion and wear of graphite and non-oxide refractory parts and tools increasing lifetime
- Inorganic binder improves adhesion
- Coating durability shortens downtimes
- Safety and cleanliness of operation area: no open flames and gases in comparison with more traditional release agents such as oils, greases, etc.
- Economical consumption
- Easy to process
