WEST SYSTEM 205 Fast Hardener is a low-viscosity epoxy curing agent for use when shorter working and cure time is needed or to provide adequate working time at cooler temperatures as low as 40F.
At 72F, 205 Fast Hardener will have a 9-12 minute Pot Life. The ideal mixing ratio is five-part WEST 105 Resin with one-part hardener for a stable mix. This cured resin/hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties. To ensure the right resin-to-hardener ratio, use the WEST SYSTEM 300 Mini Pump Set for accurate metering.
Not intended for clear coating. Available in pint, quart, and gallon sizes.

This being my first time using West System, I couldn't be happier. Using the metering pumps was so much easier than trying to measure out exact volumes. The project came out very good.
