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|
