West System

The West System 205 Fast Hardener is great for use in general bonding, fabric application and barrier coating at low temperatures. This is a medium-viscosity epoxy curing agent that cures rapidly and strengthens its physical properties in room temperature.

It is mixed at 5:1 resin-hardener ratio to create rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.

  • Medium-viscosity epoxy curing agent
  • Cures faster at room temperature
  • High-strength, moisture-resistant solid
