205 Fast Hardener - 11.15 Gallon (Group Size E)

205 Fast Hardener is a medium-viscosity epoxy curing agent. It is used in a majority of situations at lower temperatures to produce a rapid cure that develops its physical properties quickly at room temperature. When mixed with the 105 Resin in a five-part resin to one-part hardener ratio, the cured mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties.
