This material can be used to coat caststeel mould for aluminium casting ingot process?
If yes, how to apply into the mould. How long this lasts? What is the price? Where is possible to find it?
Is this hazardous material or has any impact to the environment?
Mozal is primary aluminium smelter, we are looking for ingot releasing material to replace the canola oil.
