DESCRIPTION:  ZIRFLOW 290MB is a blend of fused zircon/zirconia refractories designed for iron and steel castings.  ZIRFLOW 290MB can be applied by brushing, dipping, flow coating, or spraying.  The rheological properties of ZIRFLOW 290MB contribute to improved workability and consistency, thus providing improved surface finish and casting quality. Because of the excellent suspension of ZIRFLOW 290MB, minimal settling occurs which allows for easy redispersion.  The coating is designed to be reduced with water at the customer’s facility.
