Features & Benefits

Performance Characteristics
  • Effective temp. range 1000-2350⁰F (538-1288⁰C)
  • 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 (generally, the higher the temperature and longer exposure, the thicker the coating should be applied)
  • A wet film thickness of 6 ± 3 mils should be optimal
  • Ensure bottom coat is thoroughly dried when applying multiple coats
  • Water-based coatings need ample time to completely dry before entering furnace (can be applied over preheated substrate to accelerate drying time)
