    West System 205 Fast Hardener is a medium-viscosity epoxy curing agent suitable for use at lower temperatures and to produce a rapid cure that develops its physical properties quickly at room temperature.

    Features:

    • 105 / 206 mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties
    • Wets out and bonds to wood fiber, fiberglass, reinforcing fabrics, foam and other composite materials, as well as a variety of metals
    • 105 / 205 Epoxy can be thickened with West System fillers to bridge gaps and fill voids and can be sanded and shaped when cured
    • With roller applications, has excellent thin-film characteristics, allowing it to flow out and self-level without "fish-eyeing"
    • Multiple coats of 105 / 205 Epoxy create a superior moisture barrier and a tough, stable base for paints and varnishes
    • Formulated without volatile solvents
    • Has a relatively high flash point, no strong solvent odor and does not shrink after curing
    • It is not intended for clear coating natural finished wood

    Handling characteristics:

    • Mix ratio: (5) parts resin : (1) part hardener
    • Pot life at 72°F (22°C): 9 to 12 minutes
    • Cure to solid state: 6 to 8 hours
    • Cure to maximum strength: 1 to 4 days
    • Minimum recommended temperature for curing: 40°F (4°C)

    For further details See Data Sheet for This Product

    * Dispensing and Mixing

    • Dispense the proper proportions of resin and hardener into a clean plastic, metal or wax-free paper container
    • Don't use glass or foam containers because of the potential danger from exothermic heat buildup
    • DO NOT attempt to adjust the epoxy cure time by altering the mix ratio
      • An accurate ratio is essential for a proper cure and full development of physical properties
    • Dispensing with Mini pumps
        • Most problems related to curing of the epoxy can be traced to the wrong ratio of resin and hardener
        • To simplify metering, we recommend using calibrated WEST SYSTEM Mini Pumps to dispense the resin and hardener
        • Mini Pumps are calibrated to deliver the proper working ratio of resin to hardener
        • Pump one full pump stroke of resin for each one full pump stroke of hardener
        • Depress each pump head fully and allow the head to come completely back to the top before beginning the next stroke
      • Partial strokes will give the wrong ratio
      • Read the pump instructions before using pumps
      • Before you use the first mixture on a project, verify the proper ratio according to the instructions that come with the pumps
      • Re-check the ratio anytime you experience problems with curing
    • Dispensing without Mini Pumps (Weight/volume measure):
      • To measure 105 Resin and 205 or 206 Hardener by weight or volume, combine five parts resin with one part hardener
      • To measure 105 Resin and 207 or 209 Hardener by volume, combine three parts resin with one part hardener (by weight, 3.5 parts resin-1 part hardener)
