Cure Method
Curing Conditions

Cure speed will vary with temperature, relative humidity, depth of material and presence of moisture. Some applications may require special surface preparation. At 21 - 25°C, 45 - 55% relative humidity, typical cure depth is 2mm in 24 hours. Requires more time to cure in colder or lower humidity conditions.

General Instructions
  • For best performance bond surfaces should be clean, dry and free of any contaminants and oils.
  • Apply a continuous and even bead of silicone to one surface.
  • Assemble parts immediately. Remove excess material at once.
