Introduction and application of iron oxide pigments

Iron oxide pigment is a kind of inorganic color pigment with large quantity and wide area. Iron oxide pigments have high coloring power, fine and uniform particle size.

The color of iron oxide pigment is very clear and pure, and it is not polished with other organic or inorganic pigments. Although it is not as bright as some organic pigments or other pigments, the tone of iron oxide pigments has a unique style, its soft, quiet and harmonious tone is pleasant to the eye.

High chemical stability and physical fastness:

Alkali resistance: to any concentration of alkali and other kinds of alkaline substances, especially buildings

Commonly used cement, lime mortar and so on are very stable, and the cement building components do not occur chalking effect, also does not affect its strength.

Acid resistance: It has certain resistance to general weak acids and dilute acids, but it can also gradually dissolve in strong acids, especially in the case of heating and concentration.
Light resistant: in strong sunlight exposure color unchanged.

Heat resistance: in a certain temperature limit is stable, beyond its temperature limit color began to change, with the increasing temperature, the degree of change is more and more significant.

Weather resistance: not affected by the atmosphere of cold and heat, dry and wet climate conditions.

Resistant to dirty air: it is very stable in any dirty gas, such as hydrogen sulfide, carbon oxide, sulfur oxide, hydrogen chloride, nitrogen oxide and other gases.

Water resistance, oil resistance, solvent resistance permeability: not dissolved in water, various mineral oils, vegetable oils and ether, esters, ketones and other organicsolvents, and no permeability phenomenon.

Application of iron oxide pigment

For cement building materials

Due to its good weather resistance, alkali resistance and light resistance, these properties are not other inorganic pigments or organic pigments can be combined so iron oxide pigments are applied as coatings and coloring in building materials.

Application in paint

It has good weather resistance, high purity, good thermal stability, good solubility with other ingredients in the application system, can absorb ultraviolet light, prevent the degradation of the base material,can be widely used in paint. Because of the strong hiding power, the UV has a very strong impermeability and very small water absorption, in the paint film can enhance the mechanical strength of the paint film, especially in the adhesion of the excellent characteristics of other anti-rust pigments.

For rubber and plastic

In the application of rubber plastics, iron oxide red with no copper, manganese and other heavy metal ions can be used in aviation tires to prevent the aging of rubber.

Iron oxide pigment has the characteristics of strong coloring power and pure color. It can be used as colorant and filler in PVC plastic floor and PVC colored film. It can be used in thermosetting plastics.

Iron oxide pigments, such as color masterbatch or paste preparation, will be more popular in the material industry.
