We don't guarantee a same date if testing under different conditions, or when data was regenerated).   Warm tips for for pcb electronic potting silicone  1. Sealing pakage for storage. The mixture should be used up at once to avoid wasting.  2. Silicone belongs to non-dangerous goods, but keep away form mouth and eyes.  3. When it gets stratified after a period of storage, please mix hy-210# evenly before using,       it does not affect the performance.     Shelf life and transportation 1. Twelve(12) months when stored at 25c in original unopened packages. 2. This is a non-dangerous product, it can be transported as general chemicals. 3. Products exceed the storage life should be confirmed normal before using.
