NOTE 1: If the storage temperature is over or under 25 °C (77 °F) this will influence the storage time. Storage at 10 °C (50 °F) higher will reduce the storage time by about 50%. Storage at 10 °C (50 °F) lower will increase the storage time by around 100%.
NOTE 2: In application areas such as aerospace, the storage periods can differ from this specification. These specific storage conditions have to be agreed between the supplier and the buyer.
*These are general temperature ranges. For ranges of specific compounds, please contact Trelleborg Sealing Solutions Chemical Transportation.
