Ultra-pure zircon oxide paste (zircon gel) as coating providing coating against melt reactions between graphite frames and the material to be hardened.  It is able to replace expensive ceramic or molybdenum melting barriers to a large extent.

ZIRC-LABEL is applied as a thin  parting layer direct to the clean, dust and grease-free graphite (CFC) surface.  It prevents graphite-metal reactions in vacuum furnaces.

Ideal for
  • CFC frames
  • Graphite supports in vacuum furnaces
  • Crucibles
  • Cores
ZIRC-LABEL is easy to handle and environmentally compatible since it is waterbased. Brushes and other tools can be cleaned with water and the viscosity optimized by the addition of water.

  • Temperature range: 1900 °C (> 3500 °F)
  • Contains no silica
  • Easy to apply
  • High chemical resistance
  • Can be dissolved excellently
