Protect against weathering. Store in a dry place and avoid extreme fluctuations in temperature. Close bags after use to prevent the absorption of moisture and contamination. Bayferrox® 3920 has an excellent shelf life. When storing large quantities of pigments, temperatures above 120°C must be avoided as an alteration (dehydratisation and oxidation) of the pigment may be caused by heat.We recommend that this product is used within ten years of the date of manufacture and limit our product warranty to this period. During the first ten years after the date of manufacture we are able to ensure compliance with this specification, provided the material has been stored as stated above and the packaging materials remain undamaged. The different packaging materials are given below:

• All kinds of bags (Paper and PE) - 5 years
• All kinds of Bulk bag - 3 years

With respect to Bulk Bags, its recommend to avoid UV-radiation because the sewing material of the lifting loops is stabilized against degradation by UV-radiation for approx. 1000 h incident sun radiation for the climate of Central Europe. A more intense sun radiation can shorten this period significantly. In cases of doubt the lifting loops must be checked thoroughly.
