West System 206 Hardener
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.
It also provides adequate working time at higher shop temperatures. When combined with 105 Resin in a five-part epoxy resin to one-part hardener ratio, the cured resin/206 Slow Hardener mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and barrier coating properties. 206 Slow Hardener is not intended for clear coating.
