DESCRIPTION:  ZIRFLOW 279 is a zircon water based coating designed for iron and steel castings.  ZIRFLOW 279 can be applied by brushing, dipping, flow coating, or spraying.  The rheological properties of ZIRFLOW 279 contribute to improved workability and consistency, providing improved surface finish and casting quality. ZIRFLOW 279 is designed to reduce drying time significantly. Because of the excellent suspension of ZIRFLOW 279, minimal settling occurs which allows for easy redispersion. The coating is designed to be reduced with water at the customer’s facility.
