Product group
01 Impregnating agent
02 Hardening agent
Packaging size
Field of application
  • Grouting / coating of coils
  • Small electrical and electronical capsules
  • Adhesion and seals
  • Heat-resistant applications
  • Unfilled two-component epoxy resin system (free from solvents and plasticizers)
  • Pay attention during mixture that no air bubbles are included. If necessary, effect a vacuum degassing and/or preheat corresponding parts
  • Manual or automatic moulding
  • Hardening at room temperature with subsequent heat stabilization in furnace or with short-term heating

Characteristics by secondary hardening:

  • Strong hardness
  • Very high thermal resistance
  • Very high chemical resistance
  • Good adhesion
Secondary hardening
  • Necessary, if object works at temperature
  • Heat up object by 10°C per hour to the temperature indicated in the table (slower for large masses)
  • Keep temperature during indicated time (with large masses keep it longer)
  • Secondary hardening for application of thin coats and Composite
  • Optimal hardening and secondary hardening conditions vary according to shape and size
  • 2 years durable in original packaging (store cool and dry)
  • The container of the hardener should be closed immediately after use, because the hardener is sensitive to humidity.
