West System 206 Slow Hardener

West System 206 Slow Hardener is a low-viscosity epoxy curing agent for use when extended working and cure time is needed or to provide adequate working time at higher temperatures.

Features:

• 105 / 206 mixture yields a rigid, high-strength, moisture-resistant solid with excellent bonding and coating properties
• Wets out and bonds to wood fiber, fiberglass, reinforcing fabrics, foam and other composite materials, as well as a variety of metals
• 105 / 206 Epoxy can be thickened with West System fillers to bridge gaps and fill voids and can be sanded and shaped when cured
• With roller applications, has excellent thin-film characteristics, allowing it to flow out and self-level without "fish-eyeing"
• Multiple coats of 105 / 206 create a superior moisture barrier and a tough, stable base for paints and varnishes
• Formulated without volatile solvents
• Has a relatively high flash point, no strong solvent odor and does not shrink after curing
• It is not intended for clear coating natural finished wood

Handling characteristics:

• Mix ratio: (5) parts resin : (1) part hardener
• Pot life at 72°F (22°C): 20 to 25 minutes
• Cure to solid state: 10 to 15 hours
• Cure to maximum strength: 1 to 4 days
• Minimum recommended temperature for curing: 60°F (16°C)
