Storage & Handling
- HANDLING AND STORAGE
- EPAMINE curing agent may absorb moisture and CO2 if drums are not well closed.
- EPAMINE curing agent should be stocked in dry place at a temperature between 5 and 35°C; in this condition, self life is at least 1 year, from the date of manufacture, if in the original sealed container.
- Lower temperature could bring increase in viscosity (reversible) and haziness.
- EPAMINE curing agents and epoxy resin must be mixed just before application; avoid contact with eyes and skin, do not inhale vapors, wear protective clothes, glasses and gloves. Use only with adequate ventilation.
