West Systems 206 Slow hardener is intended to be used with 105A epoxy resin. It is intended for general bonding, fabric application, and barrier coating.
Slow hardener works best at room temperature, but can be used anywhere from about 60 to 90 degrees Fahrenheit.
206 slow is primarily used when extended working time is needed, or else to provide a longer pot life at high temperatures.
It provides about a 20-25 min pot life, 10-15 hours for a solid cure, and 1-4 days to reach maximum strength at room temperature.
