Storage & Handling
- Shelf Life
- Out Life: 28 days out life ≤ 21°C (70°F) and ≤ 60% RH
- Frozen Storage Life: 12 months at ≤-18°C (≤ 0°F)
Out life is the maximum time allowed at 21°C (70°F) or below and 60% or less RH before cure, after a single frozen storage cycle in the original unopened packaging at -18°C (0°F) or below for a period not exceeding the frozen storage life noted above.
