Overview
Quinacridone Red, also known as Pigment Red 122, is a synthetic organic pigment renowned for its vibrant red color and exceptional performance properties. It belongs to the quinacridone family, which is widely used in high-end applications requiring durability and color stability. The pigment is synthesized through a complex chemical process, resulting in a crystalline structure that contributes to its superior lightfastness and resistance to weathering. Its molecular stability makes it a preferred choice for demanding industrial and automotive applications.
Physical and Chemical Properties
Quinacridone Red exhibits a bright red hue with excellent opacity and tinting strength. Its crystalline structure ensures high thermal stability, making it suitable for processes involving elevated temperatures, such as plastic extrusion. The pigment is chemically inert, resisting degradation from acids, alkalis, and solvents. This property, combined with its insolubility in water, ensures long-lasting color performance in harsh environments. Its density of approximately 1.5 g/cm³ and fine particle size contribute to its ease of dispersion in various media.
Main Applications
Quinacridone Red is extensively used in automotive coatings, where its weather resistance and color retention are critical. It is also a staple in industrial paints, providing durable and fade-resistant finishes for machinery and structures. In the plastics industry, the pigment is employed for coloring products such as PVC, polyethylene, and polypropylene. Its stability at high temperatures makes it ideal for injection molding and extrusion processes. Additionally, it is used in high-quality inks for packaging and printing applications.
Safety and Storage
While Quinacridone Red is generally considered safe for industrial use, proper handling precautions are necessary. Avoid inhalation of dust and direct contact with skin or eyes. Use personal protective equipment (PPE) such as gloves and masks when handling the powder. Storage should be in a cool, dry environment, away from moisture and direct sunlight. Containers must be tightly sealed to prevent contamination and degradation. Proper labeling and adherence to local safety regulations are essential for safe storage and handling.
B2B Procurement Guide
When procuring Quinacridone Red, verify the CAS number (980-26-7) to ensure product authenticity. Request certificates of analysis (CoA) from suppliers to confirm purity and compliance with industry standards. Consider the pigment's intended application when selecting a grade, as particle size and dispersion properties can vary. Pricing typically ranges from $50 to $150 per kilogram, depending on quantity and supplier reputation. Establish long-term relationships with reputable suppliers to ensure consistent quality and reliable delivery.
