In the vast range of applications for organic pigments, phthalocyanine blue pigments have become indispensable blue colorants in the industrial sector, thanks to their excellent properties and versatility. Among them, PB15:3 (stable β-phthalocyanine blue) stands out for its unique greenish-blue hue and superior stability. It plays a crucial role in industries such as plastics, coatings, and inks. This pigment not only overcomes the limitations of traditional pigments when subjected to high temperatures or outdoor conditions, but also offers excellent cost-effectiveness, making it the preferred blue pigment for many engineers. This article will provide a comprehensive overview of this popular product, covering its properties, applications, and advantages. This will help you make informed decisions when selecting the right pigment for your specific needs.
Performance
PB15:3 pigment belongs to the copper phthalocyanine class of organic pigments. It represents a stable β-crystal form within the phthalocyanine blue family, with outstanding core properties.
Hue and coloring power: It produces bright green and blue colors with pure and rich hues. It’s considered one of the standard blue references in the industry. Its coloring power is extremely high; even small amounts are sufficient to achieve highly saturated colors. Its efficiency in coloring far exceeds that of traditional inorganic blue pigments.
Heat stability: The thermal decomposition temperature is over 260°C. It can easily handle high-temperature processing scenarios such as plastic injection molding and powder coating curing. There is no significant change in color or migration during processing. This makes it ideal for the production of engineering plastics and high-temperature coatings.
Light and weather resistance: Its outdoor weather resistance rating is 7-8. Even when exposed to ultraviolet rays and harsh weather conditions over long periods of time, its color remains stable. It doesn’t fade or become powdery. This makes it an ideal choice for outdoor products and industrial coatings.
Chemical and solvent resistance: It exhibits excellent resistance to acids, alkalis, oils, and solvents. It does not dissolve or discolor in common acidic, alkaline environments or solvent systems. It is suitable for use in various coating systems, including water-based, solvent-based, and powder-based ones.
Dispersion and compatibility: The particles are evenly distributed, making them easy to disperse within the resin matrix. They are also highly compatible with most polymers and resins. There’s no tendency for flocculation or discoloration, ensuring consistent color in the final product.
Applications
With its comprehensive performance advantages, the PB15:3 can be used in almost all industrial fields where blue coloring is required.
- Plastic coloring: This is one of the most commonly used blue pigments in the plastics industry. It’s suitable for use with various plastics such as PVC, ABS, PP, PE, and PC. It can be used in products like household appliance casings, automotive plastic parts, pipes, and toys. This pigment meets the requirements of various manufacturing processes, including injection molding, extrusion, and blow molding.
2. Coatings and Inks: Widely used in original and repair paints for automobiles, industrial anti-corrosion coatings, exterior wall coatings for buildings, roll-to-roll coatings, and powder coatings. These products are also compatible with solvent-based inks, water-based inks, and plastic inks. They perform stably in packaging printing, packaging materials, and industrial labeling applications.
3. Other fields: It is also widely used in rubber products, textile printing, educational supplies, and the dyeing of synthetic fiber raw materials. It’s particularly suitable for products that require high levels of weather resistance, sunlight resistance, and resistance to color migration.
Advantages
Compared to other blue pigments, the advantages of PB15:3 are particularly evident in practical applications:
Balanced overall performance: There are no significant performance weaknesses. It meets high industry standards in terms of heat resistance, light resistance, and chemical resistance. It’s highly adaptable and can meet the requirements of various demanding application scenarios.
Outstanding cost-effectiveness: The synthesis process is well-established, ensuring high stability during mass production. The price is reasonable. Additionally, the high coloring power requires only small amounts of the substance to be used, significantly reducing overall costs for customers. The cost-performance ratio is significantly better than that of imported pigments with similar properties.
Wide application compatibility: Whether it’s plastics processed at high temperatures, coatings used outdoors over long periods, or inks from various systems, this product maintains stable performance across all these applications. There’s no need to frequently change the type of pigments depending on the application, simplifying the customer’s formula management process.
Target customers
Plastic masterbatch manufacturers, plastic injection/extrusion processing plants, especially those in industries such as home appliances, automotive parts, and building materials.
Paint manufacturers, including those specializing in industrial coatings, architectural coatings, powder coatings, and automotive paints.
Ink manufacturers, suitable for producing various types of printing inks, including solvent-based, water-based, and plastic inks.

Technical personnel
From a technical application perspective, PB15:3 is a “low-risk, high-performance” pigment choice. Its stable β-crystal structure prevents color shifts caused by crystal phase transitions. It also has excellent dispersibility and does not tend to agglomerate during high-shear processing. This ensures consistent colors across different batches.
For formulators, it achieves excellent dispersion without the need for additional dispersing agents. It also mixes well with other phthalocyanine and organic pigments, allowing for the creation of a wide range of blue shades. Additionally, its low migration rate and high temperature resistance help to minimize quality issues that may arise during the product’s later use, thereby reducing post-sales risks.
Conclusion
PB15:3 Phthalocyanine blue pigment has become a “timeless classic” in the field of industrial blue coloring, thanks to its balanced properties, wide range of applications, and excellent cost-effectiveness. Whether it’s plastic processing where color stability is crucial, coating products that require long-term weather resistance, or ink systems that need efficient coloring, PB15:3 offers reliable solutions for all these applications.
Choosing PB15:3 is not just about selecting a pigment. It’s also about getting a reliable, efficient, and hassle-free solution for coloring.
