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. When combined with 105 Resin in a five-part resin to one-part hardener ratio the cured resin/hardener mixture yields a rigid high-strength moisture-resistant solid with excellent bonding and coating properties. Pot Life at 25C:20 to 30 minutes Cure to a solid state at 21C: 9 to 12 hours Cure to maximum strength at 21C:5 to 7 days Minimum recommended temperature: (16C)
