Storage    - Storage in original sealed Bayer MaterialScience container.
                     - Recommended storage temperature: 5 - 30 °C.
                     - Protect from frost, heat and foreign material.
                     General information: The product cannot be used if it has
                     been frozen. Thecontainers must be well closed to prevent the
                     evaporation of water which may result in the formation of a
                     non-redispersible film. Brief heating to max. 50 °C has no
                     adverse effect on product properties.
Storage time         Bayer MaterialScience represents that, for a period of six
                     months following the day of shipment as stated in the
                     respective transport documents, the product will meet the
                     specifications or values set forth in section "specifications
                     or characteristic data" above, what ever is applicable,
                     provided that the product is stored in full compliance with
                     the storage conditions set forth in and referenced under
                     section "storage" above and is otherwise handled appropriate
                     ly.The lapse of the six months period does not necessarily
                     mean that the product no longer meets specifications or the
                     set values. However, prior to using said product, Bayer
                     MaterialScience recommends to test such a product if it
                     still meets the specifications or the set values. Bayer
                     MaterialScience does not make any representation regarding the
                     product after the lapse of the six months period and Bayer
                     MaterialScience shall not be responsible or liable in any way
                     for the product failing to meet specifications or the set
                     values after the lapse of the six months period.
