Suggested Applications
  • Epoxy Glass Lamination: Excellent wetting out properties
  • Thin Glue-Line Bonding: No bulky filler to occupy space
  • Void-Free, See Through Castings: Low viscosity, air released rapidly
Room Temperature Cure
  • H-1 Hardener: Offers a working time of 30 minutes. Cures in 6 hours at 25°C or 30 minutes at 65°C. Produces a tough, rigid resin with good dimensional stability. Do not heat cure if the mass exceeds 100 grams.
  • H-18 Hardener: Offers a working time of 45 minutes. Cures in 24 hours at 25°C or 2 hours at 65°C. Produces a tough, resilient resin with good mechanical and thermal shock properties.
  • H-10LV Hardener: Offers a working time of 3 hours. Cures in 24 hours at 225°C or 3 hours at 65°C. Produces a variable hardness resin with excellent impact properties.
Mixing Instructions

Weigh out the desired amount of resin in a clean container. Add the hardener accurately by weight in the proper proportion as specified above. (ie. 14 grams of H-1 Hardener and 100 grams of CC3-105 for a total mix of 114 grams) Mix thoroughly. Use in a well ventilated area and avoid contact with eyes and skin.
