  • Extra-slow curing hardener for warm conditions – WEST SYSTEM 209 Extra Slow Hardener is a low-viscosity epoxy curing agent designed for bonding and coating applications in extremely warm or humid environments where extended working time is needed.
  • Designed for use with WEST SYSTEM 105 Epoxy Resin – Mix at a 3:1 ratio with 105 Epoxy Resin to create a high-strength epoxy system that cures to a clear amber, moisture-resistant solid suitable for bonding and coating applications.
  • Extended working time for complex repairs – Provides roughly twice the working time of 206 Slow Hardener, with a pot life of about 40-50 minutes at 72°F and approximately 3-4 hours of working time in a thin film.
  • Gradual cure with strong final properties – The epoxy mixture cures to a solid state in about 20–24 hours at 72°F and develops maximum strength over several days, allowing careful bonding and coating work.
  • Compatible with fillers and additives – The cured epoxy can be modified with WEST SYSTEM fillers, pigments, and additives for coating, fiberglass work, structural bonding, or fairing, though 209 is not intended for clear coating applications.

WestSystem Painting Supplies Editorial Review

The West System 209-SB Extra Slow Hardener is celebrated by users for its high-quality performance and versatility, particularly among those engaged in complex composite projects such as long fiber reinforced forged carbon parts. Users commend the extra slow curing time, which allows for ample working time even in challenging conditions like high temperatures, where it still provides a working window of 30 to 45 minutes. This extended period is invaluable for meticulous tasks, enabling users to accurately place fibers and complete their work without the pressure of rapid setting. Moreover, the product's endorsement by reputable sources like Burt Rutan adds to its credibility and makes it a preferred choice over competitors, especially given its availability on platforms like Amazon, which negates high shipping fees often associated with similar products from specialty suppliers. While many users sing its praises, there is some disappointment regarding the packaging, specifically the quantity being less than expected. However, the exceptional quality of the resin leads most to overlook such minor grievances. In summary, the West System 209-SB Extra Slow Hardener is lauded for its superior quality and flexibility in application, making it a highly recommended product for composite work. **
