West System 209 Extra Slow Hardener for R105 Epoxy Resin is formulated for general coating and bonding applications in extremely warm and / or humid conditions, or when extended working time is desired at room temperature. It provides approximately twice the working time of 206 Slow Hardener, and forms a clear, amber-coloured solid with good physical properties and moisture resistance for bonding and coating applications. It is not intended for clear coating.
Mix Ratio: 1 Part hardener (H207 or H209) to 3 parts resin by volume / 3.5 parts resin by weight.
