Iron oxide black factory pigments have a powdery appearance, with colors ranging from red, yellow, orange, blue, green, brown, and black, and have excellent physical and chemical properties. Strong covering power, high coloring power, soft color, stable performance, alkali resistance, certain stability to weak and dilute acids, light resistance, weather resistance, insoluble in water and organic solvents, excellent rust prevention and UV resistance.
Iron oxide pigment product characteristics:
Bright and clear color and unique tone with high chemical stability and physical fastness:
Alkali resistance: Resistance to any concentration of alkalis and other types of alkaline substances, especially in buildings
The commonly used cement, lime mortar, etc. are very stable, and do not pulverize cement building components, nor affect their strength.
Acid resistance: It has certain resistance to general weak and dilute acids.
Light resistance: The color does not change under strong sunlight exposure.
Heat resistance: Stable within a certain temperature limit.
Climate resistance: It is not affected by weather conditions such as cold, heat, dry, and wet in the atmosphere.
Resistant to dirty air: It is very stable in any dirty gas.
Resistance to water, oil, and solvent penetration: insoluble in water, various mineral oils, vegetable oils, ethers, esters, ketones, and other organic solvents, and without penetration.
