- Usage Guidelines
A stoichiometric amount of epoxy and hydroxy groups is recommended. The following formula should be used to calculate the correct amount of epoxy hardener: Amount of hardener (g) = amount of epoxy resin (g) X (hydroxyl equivalent weight of hardener (g/eq) / epoxy equivalent weight of resin (g/eq))
- Storage and Handling
GP 2056 epoxy hardener is shipped in boxes and is non-heat-reactive. It should be stored and used in areas with good ventilation and stored in a cool, dry place at temperatures below 20-25°C. Storage in sunlight, high temperatures and/or humidity can cause cold flow and lumping. Storage life under the recommended conditions is 12 months. Proper protective equipment should be used whenever the resin is handled. For additional safety and health information, refer to the Safety Data Sheet for this product available from Georgia-Pacific Chemicals.
