209 Extra Slow Hardener
WEST SYSTEM 209 Extra Slow Hardener™ is used for general coating and bonding applications in extremely warm and/or humid conditions. It is also used when extended working time is desired at room temperature.
This hardener forms a clear, amber-coloured solid with good physical properties and moisture resistance for bonding and coating applications. It also provides approximately twice the working time of 206 Slow Hardener®.
