          West System 206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working and cure time is needed or to provide adequate working time at higher temperatures.


          • 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 / 206 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 / 206 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): 20 to 25 minutes
          • Cure to solid state: 10 to 15 hours
          • Cure to maximum strength: 1 to 4 days
          • Minimum recommended temperature for curing: 60°F (16°C)

          Rated 5 out of 5 by from West System 206 Hardener Slow Enough for Hot Days This is just what I needed, I had to replace the stainless steel tube for my centerboard on my C&C32 shoal draft with centerboard. It was September in Annapolis with consistent daytime temps hitting the 90's. This hardener gave me the time I needed to work with the epoxy and lay up the glass at the base of the tube.
