Product Details

The West System 209SB Extra Slow Hardener is specifically formulated for use with 105 Resin in extremely warm and humid conditions. This professional-grade hardener is ideal for general bonding and coating applications where extended working time is critical for proper application and finishing.

Key Features:

  • Provides approximately twice the pot life and working time compared to 206 Slow Hardener
  • Maintains adequate pot life in temperatures up to 110°F
  • Specifically designed for extremely warm and humid environmental conditions
  • Compatible with West System 105 Resin for optimal performance
  • 0.33 gallon (quart) container size for convenient project use
  • Ideal for laminating, bonding, fairing, and barrier coating applications

This extra slow hardener is the preferred choice for professional boat builders, marine repair technicians, and composite fabricators working in hot climates or during summer months when standard hardeners cure too quickly. The extended working time allows for careful layup of large composite parts, meticulous surface coating, and complex bonding operations without rushing.

Applications: Marine construction and repair, fiberglass lamination, wood boat building, composite fabrication, structural bonding, and protective coating systems in warm weather conditions.
