West System 209-SA Extra Slow Hardener

209 Extra Slow Hardener is formulated for use with WEST SYSTEM 105 Resin for general coating and bonding applications in extremely warm and/or humid conditions or when extended working time is desired at room temperature. Provides approximately twice the working time of 206 Slow Hardener. Forms a clear, amber-colored solid with good physical properties and moisture resistance for bonding and coating applications. Not intended for clear coating. 209 SA size hardener is matched for use with 105 A size resin. Cans possibly come 2/3 full which is the appropriate amount to be mixed with 105-A ( quart )

• 209 EXTRA SLOW HARDENER is a low-viscosity epoxy curing agent. It is useful in a majority of hot-weather bonding situations, and when very long working time and cure time are needed. 209 Extra Slow Hardener produces a slow epoxy cure that develops physical properties gradually at room temperature. It yields a rigid, high-strength moisture-vapor resistant and functionally waterproof solid.
• USE WITH WEST SYSTEM 105 RESIN for general coating and bonding applications in extremely warm and/or humid conditions, and for extended working time at room temperature. Forms a clear, amber-colored solid with good physical properties and moisture resistance for bonding and coating applications.
• PROVIDES ABOUT TWICE the working time of 206 Slow Hardener. 209's pot life at 72°F (22°C) is 40 to 50 minutes. Pot life at 95°F (35°C) is 15 to 20 minutes. Cures to a solid state at 72°F (22°C) in 20 to 24 hours. Cure to a solid state at 95°F (35°C) in 6 to 8 hours. Reaches maximum strength at 72°F in 4 to 9 days Minimum recommended working temperature is 70°F (21°C).
• PAIR WITH WEST SYSTEM 105-A Epoxy Resin. Blend with with WEST SYSTEM 105 Epoxy Resin at a 3-parts resin to 1-part hardener ratio.
• EASILY MODIFIED with WEST SYSTEM Fillers, Additives, and Pigments to suit the job at hand, whether coating, applying fiberglass, structural bonding, or fairing. Not intended for clear coating.
