The West System 206 Slow Hardener is ideal for general bonding and coating applications. It is a low-viscosity epoxy curing agent that can be used when prolonged cure time is required to provide enough working time at high temperatures.

This agent when mixed with 105 resin in the ratio of 5:1 (resin-hardener) gives you a highly strong and moisture resistant solid. This hardener is perfect for general bonding, fabric application and barrier coating.
