    Warning This product ships ground only


    West System 209 Extra Slow Hardener is formulated specifically for use with West System Brand 105 Resin for general coating and bonding applications in extremely warm and/or humid conditions or when extended working time is desired at room temperature.

    Features:

    • Provides approximately twice the working time of 206 Slow Hardener
    • 105 / 209 mixture forms a high-strength, moisture-resistant solid with excellent bonding and barrier coating properties
    • Wets out and bonds to wood fiber, fiberglass, reinforcing fabrics, foam and other composite materials, and a variety of metals
    • 105 / 209 mixture 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 / 209 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
    • Not intended for clear-coating natural finished wood

    Handling characteristics:

    • Mix ratio: (3) parts resin : (1) part hardener
    • Pot life at 72°F (22°C): 40 to 50 minutes
    • Pot life at 95°F (35°C): 15 to 20 minutes
    • Cure to solid state at 72°F (22°C): 20 to 24 hours
    • Cure to solid state at 95°F (35°C): 6 to 8 hours
    • Cure to maximum strength: 4 to 9 days
    • Minimum recommended temperature for curing: 70°F (21°C)

    * 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)
