Processing Recommendation

Araldite® LY 1556 should be stored in a dry place, in the sealed original container, away from heat and humidity, at temperatures between +2°C and +40°C (+35.6°F and +104°F). The product should not be exposed to direct sunlight. Like many liquid epoxy resins, Araldite® LY 1556 may crystallize when stored below room temperature. Heating the resin to 60-70°C (140-160°F), preferably in a water bath, for several hours, will re-liquify it and restore its original properties. Aradur® 3492 should be stored in a dry place, in the sealed original container, away from heat and humidity, at temperatures between +2°C and +40°C (+35.6°F and +104°F). The product should not be exposed to direct sunlight.
