Ship hardener WS209C

Overview
The 209C extra slow hardener is formulated for use with resin 105 for general coating and bonding applications in extremely hot and/or humid conditions (tropical climates) or when extended working time is required at elevated temperatures. The 105/209 blend provides approximately twice the pot life and working time of the slow hardener 206 and cures to a clear amber solid with good moisture resistance and physical properties suitable for bonding and laminating.
