Refractory coatings are applied to sand moulds and cores in foundries (steel castings, grey cast iron and ductile iron, and non-ferrous metals).
By creating a high temperature barrier over the entire coated surface between casting and substrate (mould or core), these coatings reduce the thermal shock caused by sand substrate.
Coatings ensure a smooth mould surface, improve its strength, reduce reactions between the substrate and melt, and provide smooth surface of castings. Applying refractory coating also prevents certain faults, i.e. segregations, burnt-in sand, bulges/recesses and others.
Our engineers are constantly optimizing and upgrading the performance of our coatings.
