1.Product Description
Pigment Blue 15:3, a β-phase copper phthalocyanine blue pigment, stands as one of the most widely used high-performance organic pigments in the global chemical industry. Renowned for its exceptional brilliant, pure blue hue and outstanding color strength, this pigment delivers consistent, vibrant coloration across a diverse range of applications. As a polymorphic form of copper phthalocyanine, the β-phase structure of Pigment Blue 15:3 ensures superior chemical and thermal stability, making it resistant to migration, bleeding, and fading even under harsh processing conditions. It offers excellent lightfastness and weatherability, outperforming many alternative blue pigments, which makes it the preferred choice for applications requiring long-term color retention, such as outdoor coatings and automotive finishes. With its high tinting strength, only small dosages are needed to achieve the desired shade, optimizing production costs while maintaining premium color quality.
Pigment Blue 15:3 exhibits excellent compatibility with a wide variety of resin systems, including acrylics, alkyds, polyolefins, PVC, and epoxy resins, making it a versatile solution for multiple industrial sectors. In the printing ink industry, it is a staple for offset, gravure, and flexographic inks, delivering sharp, consistent blue tones for packaging, publications, and commercial printing. In the plastics sector, it is ideal for coloring polypropylene, polyethylene, PVC, and engineering plastics, withstanding high-temperature extrusion and molding processes without color degradation. It is also extensively used in water-based and solvent-based coatings, architectural paints, industrial coatings, and automotive refinishes, as well as in artist paints, textile printing, and masterbatch production. Its non-toxic, environmentally compliant formulations meet global regulatory standards such as REACH, RoHS, and FDA food contact approvals, enabling safe use in food packaging and consumer goods.
Manufactured through advanced, controlled synthesis processes, our Pigment Blue 15:3 is engineered for consistent particle size distribution, excellent dispersibility, and minimal batch-to-batch variation, ensuring seamless integration into production lines and reliable end-product performance. It offers a balanced combination of high chroma, excellent hiding power, and resistance to acids, alkalis, and organic solvents, addressing the most demanding application requirements. Whether used as a standalone blue pigment or as a component in custom color formulations (such as mixing with green or violet pigments for custom shades), Pigment Blue 15:3 provides unmatched versatility and reliability. Backed by rigorous quality control and technical support, it remains the global benchmark for blue pigments, trusted by manufacturers worldwide for its consistent quality, performance, and cost-effectiveness in industrial and commercial applications.
