206-B Slow Hardener, ..86 Quart
WEST SYSTEM epoxy cures to a high-strength plastic solid at room temperatures, by mixing specific proportions of liquid epoxy resin and hardener. This highly moisture-resistant plastic adheres to a wide range of materials, making it ideal for projects that require water and chemical resistence, and strong physical properties for structural bonding. Select from a range of hardeners and additives that allow you to tailor the mixture's handling characteristics and the physical properties of the cured epoxy to suit your working conditions and specific coating or bonding application.
These hardeners will give you the working time for the temperature and conditions you’re working in. #205 Fast Hardener, mixed at a 5:1 ratio with #105 resin, results in a pot life of 9-12 minutes at 72°F, with solid cure in 6-8 hours.
