DESCRIPTION: ZirFlow 400 is a zircon/fused alumina water based coating designed for iron and steel castings. ZirFlow 400 can be applied by brushing, dipping, flow coating, or spraying. The rheological properties of ZirFlow 400 contribute to improved workability and consistency, thus providing improved surface finish and casting quality. Because of the excellent suspension of ZirFlow 400, minimal settling occurs which allows for easy redispersion. The coating is designed to be reduced with water at the customer's facility.
