Storage & Handling
- Shelf Life
- Out Life: 21 days at ≤ 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) and ≤ 60% RH before cure, after a single frozen storage cycle in the original unopened packaging at ≤ -18°C (0°F) for a period not exceeding the frozen storage life noted above. * May be cured at 121°C (250°F) or 150°C (300°F)
