The Protecta WCC-B coating is a water based protective coating containing zirconium powder and special ceramic additives. Color from white to beige.
The Protecta WCC-B coating is used on cast steel products. It has good performance against defects arising as a result of quartz sand expansion and penetration of liquid metal. Is characterized by very good rewetting and adhesion and therefore it can be applied very well onto the surface of the casting mould or insert. Addition of ceramic modifiers provides resistance to thermal shock.
