WEST SYSTEM 205 Fast Hardener

WEST SYSTEM 205 Fast Hardener® is a medium-viscosity epoxy curing agent. It is used at lower temperatures to produce a rapid cure that develops its physical properties quickly at room temperature.

When mixed with WEST SYSTEM 105 Epoxy 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.

Pot life at 25°C: 10 to 15 minutes
Cure to solid state at 21°C: 5 to 7 hours
Cure to maximum strength at 21°C: 5 to 7 days
Minimum recommended temperature: 5°C

Epoxy cure times
Open time and cure time govern much of the activity of building and repairing with epoxy. Open time dictates the time available for mixing, application, smoothing, shaping, assembly and clamping. Cure time dictates how long you must wait before removing clamps, or before you can sand or go on to the next step in the project. Follow this link to find out more about epoxy cure times.
