Concrete Colour Oxide Supplier

One of the fastest growing markets for iron oxide pigments is decorative architectural concrete. Iron oxide pigments (IOPs) are the lifeblood of decorative concrete and a means of architectural expression. Only IOPs offer the combination of cost-effectiveness, lightfastness, durability and cement compatibility that makes colored concrete feasible. While other types of pigments have these properties, they cost several times as much as IOP. Even with IOP, the cost of pigments can be double the material cost of regular concrete, which means that other pigment types are too costly for 99% of colored concrete projects.

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 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 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 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.

$Iron oxide pigments remain stable at high temperatures and are therefore often used in products that are resistant to high temperatures, such as ceramics or refractory materials.$

Iron oxide pigments 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 have excellent weathering resistance, with high resistance to light, chemicals and climate change, and are not easily faded or discolored.

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.

Iron oxide pigments are extremely light stable and can therefore be exposed to outdoor environments for long periods of time without noticeable color fading.

Why is iron oxide so popular in construction?

Iron oxide pigments produce rich, long-lasting color in concrete and other cementitious materials. This pigment has five basic components that explain it:
Good weathering resistance.
good light resistance.
Excellent resistance of concrete to alkaline environments
tinting power (hence vibrant colors).
Fine dispersion
This means that iron oxide pigments do not deteriorate over time through a variety of irritations such as rain, extreme UV exposure and shoe rubbing. Therefore, it is assumed that a good and long-lasting color for concrete can be achieved with just one iron oxide.

How to use iron oxide pigment in concrete

The amount of iron oxide pigment in concrete products is limited to 1% to 10%. Exceeding the upper limit will reduce the mechanical strength of the products. Generally 5%～8% is appropriate.
Iron oxide pigment does not contain two compounds, lead oxide and zinc oxide, which will affect the setting time and strength.
Sometimes, concrete products need to be cured at temperatures and pressures above 200°C. Therefore, black iron oxide and brown iron oxide, which can be converted to red iron oxide at 180°C, must be heat stabilized.
Cement concrete pavement mixed with iron oxide pigment should not be too thick at one time. Generally not more than 20cm. too thick will cause the waste of iron oxide pigment for concrete, which is not economical and cannot guarantee the quality of concrete itself.
