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.
At 72-degrees, 205 Fast Hardener will have a 9-12 minute Pot Life. When combined with WEST 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.
|Mix Ratio, Resin:Hardener||5:1 by weight or volume|

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.

I recommend this in warmer weather, gives more working time than the fast hardener

If 17th and 18th century English Admiralty shipbuilders could have used epoxy for frigates, man-o-wars, ships of the line, they would have.
