Iron Oxide Red 130 Synthetic Pigment

Iron Oxide Red 130 Synthetic Pigment (CAS 1309-37-1, molecular formula Fe2O3) is a coatings raw material used by paint, ink and adhesive formulators who need consistent dispersion, opacity and rheology from drum to drum. China Chemicals supplies it at Fe2O3 96% min in pack sizes from 1 kg through to 1000 kg Bulk Bag, so laboratory trial quantities and full production volumes can be sourced from the same specification.

It is also traded as Pigment Red 101, Synthetic Red Iron Oxide, Ferric Oxide. Every consignment ships with a batch-specific Certificate of Analysis and the current Safety Data Sheet, and material is stored and picked under stock rotation so you receive product well inside its shelf life.

Typical applications

Colouring of concrete, paving and roof tiles
Primer and protective coating pigmentation
Plastics and rubber colouration
Ceramic body and glaze colourant
Ferrite and magnetic material precursor
