NEW! SuspendaSlurry® ZR material

SS

 

We are pleased to introduce SuspendaSlurry® ZR material for ferrous metal casting. Formulated with 100% zircon refractory flour, SUSPENDASLURRY ZR material provides industrial casters with a pre-made slurry that does not require continuous mixing.

  • Developed to eliminate costs associated with continuous mixing and slurries lost to electrical failure
  • Simplifies the initial mixing process by eliminating the need to weigh and mix binder and refractory components
  • Based on R&R’s leading primary binder technology, offers benefits over standard colloidal silica shells: such as stronger layers; reduced buckling, lifting or cracking defects; and simplified slurry maintenance
  • SUSPENDASLURRY ZR material is available in 100 and 600 pound slurries
