West System 206 Slow Hardener for R105 Epoxy Resin 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 temperature.  When mixed with R105 Resin at a 5:1 ratio, the cured resin / hardener mixture yields a rigid, high strength, moisture-resistant solid with excellent bonding and coating properties.  They are not intended for clear coating.
Mix Ratio: 1 Part hardener (H205 or H206) to 5 parts resin by volume.
