Molybdenum chrome red and chrome yellow pigments, with their high covering power, weather resistance, and color stability, have become essential functional inorganic pigments in industrial coating systems.
Anti-corrosion coatings
Anti-corrosion coatings are a crucial component of industrial protection systems. The properties of molybdenum-chromium red and chromium yellow pigments perfectly meet the stringent performance requirements of anti-corrosion coatings. Molybdenum-chromium red (Pigment Red 104) has excellent chemical stability. When combined with rust-preventive fillers, it forms a dense pigment layer on the surface of metal substrates. Together with the resin used to form the coating, this layer creates a physical barrier that prevents water vapor, salt spray, and corrosive substances from penetrating the surface. In applications where strong anti-corrosion protection is required, such as outdoor steel structures, marine equipment, and containers, molybdenum-chromium red is often combined with white rust-preventive pigments to create rust-proof primers that combine the appearance of red lead with long-lasting protective properties. This not only meets the requirements for visibility in industrial coatings but also enhances the coating’s resistance to salt spray and humid heat.
Chromium yellow pigments (represented by Pigment Yellow 34) play a crucial role in anti-corrosion topcoats due to their excellent lightfastness and color stability. Their high covering power helps reduce the number of coating applications, thereby lowering costs. Additionally, chromium yellow’s weather resistance ensures that the color remains stable even when exposed to outdoor conditions over time, preventing fading and chalking caused by ultraviolet radiation. In applications like road barriers and bridge structures, where coatings are exposed to harsh conditions, chromium yellow provides a distinctive warning color while maintaining the coating’s protective properties and aesthetic appearance over the long term. Moreover, chromium yellow and molybdenum-chromium red pigments, when treated with special surface coatings, can further enhance their resistance to heat and chemicals, making them suitable for use in high-temperature or acidic/alkaline environments.
Mechanical coatings
Mechanical coatings place higher demands on the heat resistance, mechanical stability, and color consistency of pigments. The use of molybdenum-chromium red and chromium yellow pigments in this field has become a well-established practice. In the coating process of construction machinery, agricultural equipment, and automotive parts, the coating must withstand high-temperature curing, mechanical vibrations and friction, as well as various outdoor conditions. Molybdenum-chromium red’s excellent heat-resistant properties enable it to maintain its color stability at curing temperatures of 180–200°C, without any discoloration or golden hues. Therefore, it’s commonly used in the production of high-temperature curing coatings for construction machinery. Its bright orange-red color also enhances the visual appeal of mechanical equipment, improving its industrial aesthetics.
Chromium yellow pigment is widely used in both primers and topcoats for mechanical coatings, thanks to its excellent coloring power and solvent resistance. In primers, chromium yellow, when combined with rust-preventive fillers, helps create a protective layer. In topcoats, when mixed with organic pigments, it can produce a range of colors from light yellow to dark yellow, meeting the color requirements of various mechanical equipment. Additionally, its resistance to mechanical wear makes it ideal for high-wear-resistant coatings in construction machinery. This property prevents the pigment from wearing off due to friction or impact from sand and stones, thus ensuring the integrity of the coating’s protective properties. In environmentally friendly mechanical coating systems like powder coatings, molybdenum-chromium red and chromium yellow pigments also perform well. They can be evenly dispersed in powder resins, resulting in coatings with consistent color and stable performance.
