The pigment yellow 180 is usually produced by the nitrogen dioxide process. Using nitrobenzene as the main raw material, the intermediate of pigment yellow 180 was produced by the reaction of sulfuric acid and nitrification agent. Then, through reduction, acid treatment, washing and other steps, the pure pigment yellow 180 particles were obtained. The production process requires strict control of temperature, pressure and PH value and other parameters to ensure the stability and purity of product quality.


The application of yellow 180 pigment is wide and varied. In the coating industry, it is widely used in indoor and outdoor coatings, industrial coatings, etc., which can give products bright and durable colors, and improve the weather resistance and light resistance of the coating. The application in plastic products is also very important, pigment yellow 180 can be used as a dye or pigment additive, making plastic products rich in color, stable, and increase its appearance texture.


In addition to coatings and plastics, yellow 180 is also commonly found in rubber products and textiles. When used as a colorant for rubber products, it can make the surface of rubber products show bright yellow; When applied to textiles, pigment yellow 180 can be dyed or printed to add bright color to the fabric and enhance the market competitiveness of the product.


As an organic pigment, pigment yellow 180 also has certain applications in the food industry. With certain heat and light resistance, pigment yellow 180 is often used as a food additive (E180) for color mixing and coloring. These foods may include yellow pastries, jams, etc., to provide consumers with a colorful eating experience.


As an excellent organic pigment, yellow 180 has been widely used in various industries. The production process is rigorous and the application field is diverse, which not only gives the product rich color, but also improves the quality and competitiveness of the product. With the development of science and technology and the increase of application demand, the application prospect of pigment yellow 180 will continue to expand, bringing more opportunities and challenges to the development of various industries.
