Storage & Handling
- Shelf Life
- Out Life*: 30 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) 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. *Out life tested by SBS on a 15 x 15 cm (6”x 6”) laminate, cured in an autoclave. Users may need to evaluate out life limits for their own Applicationss due to differing thickness, configuration, and complexity.
