Notes

 

  • ⁴⁵ -  Color values after matching of the tinting strength parameter Y, i.e. Δ L*=0.
  • ⁵³ -  Minor elements may arise from the raw materials used. However, these are firmly bound to the crystal lattice as ions.

Storage & Handling

Storage Conditions
  • Protect against weathering. Bayferrox® 511 is stored in a dry place and avoid extreme fluctuations in temperature. 
  • Bayferrox® 511 has an excellent shelf life. Bayferrox® 511 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. 
  • All kinds of bags (Paper and PE) - 5 years
  • All kinds of Bulk bag - 3 years
