West System 206 Slow Hardener, 0.94 Gal (C206C)
The 206 Slow Hardener is a general-purpose epoxy hardener formulated for use with 105 Epoxy Resin at a 5:1 mix ratio. It provides a longer working time than the 205 Fast Hardener, making it the preferred choice for warm-weather laminating, large surface coating, and complex assemblies where extra open time is essential. The cured system delivers a high-strength, rigid, moisture-resistant bond suited to structural marine applications. This 0.94-gallon jug is sized for professional yards, boatbuilders, and serious DIY owners running ongoing epoxy work.
Features
- Designed for use with 105 Epoxy Resin at a 5:1 ratio (resin to hardener)
- Pot life of approximately 20–25 minutes at 72°F (22°C) — extended working time vs. fast hardener
- Cures to a high-strength, rigid, moisture-resistant solid
- Ideal for warm-weather laminating, encapsulation, and large-area coating
- 0.94-gallon bulk format for high-volume or ongoing epoxy projects
- Compatible with metering pumps for accurate, repeatable 5:1 dispensing
Common Applications
- Large-scale fiberglass laminating and wet lay-up work
- Full hull encapsulation and barrier coat application
- Wood encapsulation and structural bonding on boats
- Multi-step assemblies in warm or humid shop conditions
- Professional yard and boatbuilding production use

Parts Desk Insights
Best Use Case: The C206C gallon size is the right choice for professional yards, production boatbuilders, or serious owners doing full hull refairing, encapsulation, or multi-coat barrier work — anyone who would burn through the smaller West System 206 Slow Hardener, 0.86 qt (C206B) quickly. It pairs directly with the 105 Resin at 5:1; recommend the West System 306 Large Capacity Metering Pump to ensure accurate ratio dispensing at this volume. For customers needing even more open time in very hot conditions or for large infusion work, step them up to the West System C209SC Extra Slow Hardener, 1.4 Gal. For finish or clear-coat applications, redirect to the Special Clear 207 hardener instead. Always confirm hazmat shipping eligibility with the customer before processing — ground-only restrictions apply in most cases.
