205 Epoxy Hardener (FAST)

  • from 1095 Incl. GST


205 Fast Hardener® (formally Z205) is a medium-viscosity epoxy curing agent. It is used in a majority of situations, at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature. When mixed with the 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating.

  • Pot Life at 72F (22C): 9 to 12 minutes
  • Cure to a solid state: 6 to 8 hours
  • Cure to maximum strength: 1 to 4 days
  • Minimum recommended temperature: 40°F (4°C)

These Hardeners are part of a TWO PART system that works ONLY in conjunction with West System 105 Resin.
