In the construction industry, iron oxide is the most commonly used pigment for the production of colored and/or decorative concrete, and for good reason; iron oxide not only produces a range of color possibilities in earth tones, but also offers many other advantages. Granulated iron oxide adds further advantages.

Iron oxide pigments are widely used in coatings, paints, plastics, rubber, ceramics, asphalt, cement and other fields to provide color stability and uniform tinting effect.
Iron oxide pigments remain stable at high temperatures and are therefore often used in products that are resistant to high temperatures, such as ceramics or refractory materials.
Iron oxide pigments are widely adopted for their stability, weather resistance and versatility, and their relatively low cost makes them a cost-effective choice for making a wide range of color products.
Iron oxide pigments have excellent covering ability, which can effectively hide the color or imperfections of the underlying layer when covering the surface.
Iron oxide pigments maintain color stability during the preparation process and do not change color when exposed to heat or light.
Compared to some other pigments, iron oxide pigments are often considered an environmentally friendly choice as they contain no heavy metals or other harmful substances.
Iron oxide pigments are mainly composed of iron and oxygen elements. Depending on the oxidation state, they can be formed into a variety of colors, such as red, yellow, brown and black.
Because iron oxide pigments are available in a variety of oxidation states, a wide range of colors can be achieved through different formulations and treatments, from bright to deep.
Iron oxide pigments are extremely light stable and can therefore be exposed to outdoor environments for long periods of time without noticeable color fading.
Iron oxide pigments have excellent weathering resistance, with high resistance to light, chemicals and climate change, and are not easily faded or discolored.
Iron oxide can be used to produce a range of shades including red, brown, yellow and black. Combined, this offers the potential for a wide range of options. The earthy tones that can be achieved with iron oxide pigments are ideally suited to the needs of the concrete industry. However, in addition to the colors offered by IOP, iron oxide is a preferred pigment for its other beneficial properties, including:
Cost effective
Non-toxic
Color stability
Durable and weather resistant
Lightfastness
Cement compatible
Highly resistant to UV exposure
