Bayferrox® 525

Bayferrox® 525 is an inorganic iron oxide pigment, also known as Iron(III) oxide or Pigment Red 101. It is a single ingredient pigment that is used in a wide range of applications, including facade coatings, paper manufacturing, and coatings for wood, plastic, and metal surfaces. It is compatible with substrates such as wood and is ideal for applications in coil coating, powder coating, and wood coating. This pigment is also suitable for industrial uses such as asphalt, mortar, plaster, and paving stones, as well as for laminates in plastics and elastomers. Bayferrox® 525 provides high durability and stability across various industrial and decorative applications.

  • ⁴⁵ Color values after matching of the tinting strength parameter Y, i.e. 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.
