    750361 West System West System 105 Epoxy Resin - Gallon 105-B

    West System 105 Epoxy Resin is the base material on which all West System 105 System epoxy compounds are built.

    Features:

    • Clear, pale yellow, low-viscosity liquid epoxy resin
    • Formulated for use with West System hardeners, it can be cured in a wide temperature range to form a high-strength solid with excellent moisture resistance
    • Contains no volatile solvents and does not shrink after curing
    • Has a relatively high flash point and no strong solvent odor, making it safer to work with than polyester or vinylester resins
    • Designed specifically to wet out and bond with wood fiber, fiberglass, reinforcing fabrics and a variety of metals when mixed at the proper ratio with a West System hardener
    • Excellent adhesive, will bridge gaps and fill voids when modified with West System fillers
    • Can be sanded and shaped when cured
    • With roller applications, has excellent thin-film characteristics to flow out and self-level without "fisheyeing"
    • Resin viscosity approximately 1000 cps at 72°F (22°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)
