Iron oxide pigment 640 brown
Iron oxide pigment 610 brown is an inorganic material made from iron oxides. Due to this, it is non-toxic, non-flammable and odorless. It is characterized by low cost, high content of iron oxide compounds, pure color, high dispersion, coverage, coloring ability, absence of abrasive impurities and easy dispersibility.
They are often used to paint concrete, plaster and other construction mixtures. And also in the production of paving slabs, polymer sand tiles, artificial facing stone, LFM, plastics, etc.
