High-performance inorganic brown pigment - Ideal for coatings, concrete paving & construction
Iron Oxide Brown 610 is a premium, inorganic iron oxide pigment manufactured for long-term color stability and excellent compatibility with cementitious systems and solvent or water-based coatings. It provides a warm brown hue, strong hiding power, and superior weathering for exterior applications.
A high tinting strength and hiding power. The light resistance, good alkali resistance. No oil permeability and water permeability. Different shade with craft, yellow brown, red brown, dark brown, etc.
Iron Oxide Brown 610 is a common iron oxide pigment used in developing building materials, paints, rubber, asphalt, sports racetracks, paper, plastic and others.

For powder: pre-wet with a small portion of the carrier (water or solvent), then use high-shear dispersion to avoid agglomerates. For concrete: add pigment slowly to the mixer and check for uniform distribution. Temperature and binder chemistry affect final shade — always run a small trial.
Note:The data contained here are based on our current knowledge and experience. It is the responsibility of user to test our products before the final application.
Iron Oxide Brown 610 — an inorganic pigment — offers superior UV stability and colorfastness in exterior paving versus organic dyes which often fade. It also resists migration and bleeding in cementitious mixes, maintaining shade consistency over time.
Start with a controlled pre-wetting step, use a dispersant suited for inorganic oxides, and apply high-shear mixing to break agglomerates. Monitor viscosity and adjust rheology modifiers as needed — we can recommend dispersant types based on your binder system.
