Performance Characteristics

  • Effective temperature range 538°C - 1260°C
  • Reduces surface defects such as forged or rolled in scale
  • Reduces secondary finishing operations
  • Spalls on cooling to leave oxide scale free surface
  • Demonstrates exceptional green strength upon proper drying to withstand cracking, chipping, peeling, etc.
  • Excellent paintability; formulated for brushing application (can be adjusted for dipping or spraying by diluting with water – do not thin coating too much)
  • Desirable heat retention properties for improved hot working operations

Recommendations for Use

  • Thoroughly suspend and mix before use
  • Metal surfaces must be free of dirt, oil, grease, metal oxides, and other materials
  • Coating thickness depends on the time and temperature of exposure
  • Ensure bottom coat is thoroughly dried when applying multiple coats
  • Water-based coatings need ample time to completely dry before entering furnace
  • A wet film thickness of 6 ± 3 mL should be optimal
