West Systems 206 Slow Hardener

206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working time or a longer cure time is needed. It also provides adequate working time at higher shop temperatures. When combined with 105 Epoxy Resin in a five-part epoxy resin to one-part hardener ratio, the cured 105 Epoxy Resin/206 Slow Hardener mixture yields a rigid, high-strength, moisture-resistant solid bond with excellent bonding and barrier coating properties. The mix ratio is 5 parts resin to 1 part hardener by volume. 206 Slow Hardener is not intended for clear coating.
