Product use
1. Construction and civil engineering field: Yellow iron oxide pigment is widely used in concrete products. By directly adding it to cement, it provides a long-lasting and stable color for prefabricated parts and building products. This pigment not only gives concrete a bright yellow color, but also improves its weather resistance and durability. In the application of colored concrete surfaces, yellow iron oxide pigment can provide a rich color selection for walls, floors, ceilings, pillars, porches, pavements, parking lots, stairs and stations. Whether indoors or outdoors, it can keep the color bright and lasting. In addition, yellow iron oxide pigment is also widely used in the production of architectural ceramics and glazed ceramics. It provides a natural and durable yellow color for tiles, floor tiles, roof tiles, panels, terrazzo, mosaic tiles and artificial marble, meeting the market's demand for personalization and decorativeness.
2. Coatings Industry: Yellow iron oxide pigment is also widely used in the coatings industry. It is suitable for water-based interior and exterior wall coatings, providing lasting protection and decorative effects for buildings. Due to its excellent weather resistance and light resistance, yellow iron oxide pigment performs particularly well in outdoor coatings. In powder coatings, yellow iron oxide pigment provides a uniform and stable color while improving the adhesion and wear resistance of the coating. This property makes powder coatings more widely used on metal and non-metal surfaces. For oil-based paints, yellow iron oxide pigment can be mixed with different types of primers and topcoats such as epoxy, alkyd, and amino to provide excellent coloring effects. It not only improves the color brightness of the coating, but also enhances its weather resistance and chemical resistance.
Yellow iron oxide pigment also plays an important role in special coatings such as toy paint, decorative paint, furniture paint, electrophoretic paint and magnetic paint. It provides these products with natural and attractive colors while meeting specific performance requirements. It should be noted that yellow iron oxide pigment is not suitable for high-temperature products exceeding 170°C.
3. Plastic and rubber industry:
In the coloring of plastic products, yellow iron oxide pigment can provide bright and stable colors. It is suitable for thermosetting plastics and thermoplastics, such as car inner tubes, aircraft inner tubes, bicycle inner tubes, etc. These plastic products are subject to varying degrees of friction and temperature changes during use, and yellow iron oxide pigment can resist these conditions and maintain color stability. For rubber products, yellow iron
oxide pigment is also a commonly used colorant. It can improve the weather resistance and wear resistance of rubber products while giving them a bright yellow color. In rubber products such as car inner tubes, aircraft inner tubes and bicycle inner tubes, the application of yellow iron oxide pigment improves the performance and safety of the products.
4. Other fields:
Yellow iron oxide pigment can also be used for the coloring of paper and leather. In paper manufacturing, it provides a natural and bright yellow color to paper, while improving the light resistance and weather resistance of paper. In the leather industry, iron oxide yellow pigment gives leather a natural yellow color, while improving its wear resistance and chemical resistance.
In addition, iron oxide yellow pigment is also widely used in the chemical industry. Due to its good chemical stability and catalytic activity, it can be used as a catalyst or raw material for the production of other iron-containing products. In certain chemical reactions, iron oxide yellow pigment acts as a catalyst to promote the reaction.
