Product brochure
Four iron oxide colours, powder or dispersion.
Iron oxides are the workhorse inorganic pigments: opaque, light and weather resistant, alkali stable and low cost per tonne. Hongda supplies the standard colours as powder and, where the line needs it, as liquid dispersions.
Yellow and brown shades
Iron oxide yellow and brown
Yellow oxides for coatings and building materials, and brown blends for earth tones in construction and plastics. Heat limits are lower than red, so state your process temperature.
Powder · transparent black dispersion
Iron oxide black and dispersions
Black oxide in powder for concrete, coatings and plastics, plus liquid dispersions such as transparent black, ready to dose in coatings and inks without in-house grinding.
Buying it right
Pigment PR 101 for primers, pavers and plastics.
Pigment PR 101 is the Colour Index name of red iron oxide, the most used iron oxide color. Buyers order it in volume, so price per ton and shade consistency decide the deal.
Hongda supplies red iron oxide for coatings, concrete products, plastics and primers, with shade and particle size stated by grade. The pigment team sends the current grade list.
Red oxide is alkali stable for cement and opaque for primers. Order it with yellow and black oxides to build earth tones in one shipment.
The partnership
What a Hongda partnership gives you.
Supply
You buy at origin, in the quantities a distributor needs to stay competitive in its market. Volume pricing, consolidated shipments and production planned around your forecast give you the economics to defend margin against any local reseller.
Product
Seven registered brands, from Dragon Dyes to Chemtech, all backed by Hongda's in-house R&D teams. Dyes, pigments, additives and functional chemicals come from the same group, so you can widen your catalogue while keeping a single supplier.
Support
Samples, datasheets and technical answers come straight from the team that makes the product. Formulation advice, matching against your current reference and follow-up after delivery are part of the partnership, included from the first order.
Experience
Documentation, logistics and compliance are routine here after three decades of cross-border trade. Hongda exports to more than 30 countries and works with over 500 distributors worldwide, so the paperwork your market requires has most likely been solved here before.

02What is pigment PR 101 used for?
Primers and coatings, concrete products such as pavers and roof tiles, and plastics in earth tones.
