West System Hardener

**NOTE** We can not ship this item internationally

7 fl oz

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. When combined with 105 Resin in a five-part resin to one-part hardener ratio, the cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. Not intended for clear coating.

Pot life at 72°F (22°C): 20 to 25 minutes
Cure to a solid state: 10 to 15 hours
Cure to maximum strength: 1 to 4 days
Minimum recommended temperature: 60°F (16°C)

Store at room temperature. Keep containers closed to prevent contamination. With proper storage, resin and hardeners should remain usable for many years. Over time, 105 Resin will thicken slightly and will therefore require extra care when mixing. Repeated freeze/thaw cycles during storage may cause crystallization of 105 Resin. Warm resin to 125°F and stir to dissolve crystals.

Hardeners may darken with age, but physical properties are not affected by color. After a long storage, verify the metering accuracy of the pumps and mix a small test batch to assure proper curing.

Tip: West System is a 2 part epoxy system that is measured by volume or weight. The volumes are NOT 50-50. We suggest you also purchase the set of 3 mini-pumps that will dispense the resin and hardener in the correct proportions. The upside to the pumps are they are very easy to use, the downside is they tend to dispense just a little more than you need. If you want to use small amounts, measure by volume using the weight ratio's listed on the containers.

Tip: Most epoxies can easily be colored by adding a drop or two of clothes dye. Start with just a drop or two. It doesn't take much.

Tip: Leave the mixing cup on the bench to cure right along with your knife. When checking the cure, check the mixing cup instead of the knife in case it hasn't set up yet. If you have a large cup full sitting to cure, be careful of heat this generates when curing. I have had a cup of this epoxy get so hot it scorched my plywood workbench top.
