    Phthalocyanine Blue (Pigment Blue 15) CAS 147-14-8

    Phthalocyanine Blue, commonly referred to as Pigment Blue 15, is supplied as an industrial organic pigment used for coloration in a wide range of material systems. It is typically selected for its strong tinting strength, color stability, and compatibility with various resin systems.

    Typical industrial uses include coatings, plastic coloration, printing inks, and related formulation systems where durable blue coloration is required. Depending on processing requirements, it may be supplied as dry powder or presscake. Standard export packaging, bulk supply, and documentation such as COA, TDS, and SDS are available to support industrial procurement.

    Packaging

    Phthalocyanine Blue is supplied either as dry powder or as presscake, depending on downstream processing requirements. Powder products are typically packed in multi-layer paper bags or fiber drums with inner liners to protect against moisture and contamination. Presscake forms are packed in lined containers or drums suitable for wet pigment handling. Packaging is arranged to maintain product stability and ease of transport.

    Storage

    Store in a cool, dry, and well-ventilated environment. Keep containers tightly sealed to prevent moisture uptake and contamination. Avoid excessive heat and direct sunlight during storage and transportation to maintain consistent pigment performance.

    FAQ - Technical & Supply Chain

    • Q:

      What is Phthalocyanine Blue Pigment Blue 15 CAS 147-14-8 used for?

      A: It is a high-strength organic blue pigment used to color industrial coatings, plastics, printing inks, rubber, and other polymer-based materials. It is selected for its strong tinting strength, high light fastness, and broad application range.
    • Q:

      Is Pigment Blue 15 a single product or a group of grades?

      A: Pigment Blue 15 is a family of copper phthalocyanine grades rather than one single product. Different crystal forms and surface treatments are available, including alpha and beta modifications, which differ in shade, heat stability, and suitability for coatings, plastics, or inks.
    • Q:

      What is the difference between alpha and beta Phthalocyanine Blue?

      A: Alpha copper phthalocyanine typically gives a redder blue shade and may require stabilization for certain systems. Beta copper phthalocyanine, such as Pigment Blue 15:3, is generally more stable and is commonly preferred for plastics and higher-temperature processing.
    • Q:

      Can Phthalocyanine Blue be used in plastics?

      A: Yes. Pigment Blue 15 is widely used in plastics such as PVC, PE, PP, and engineering resins. Grade selection should match the resin, processing temperature, dispersion method, and required fastness properties.
    • Q:

      What supply forms are available for Pigment Blue 15?

      A: It is commonly supplied as dry powder or presscake. Powder grades are used for dry blending and masterbatch or ink production, while presscake grades are convenient for water-based and wet pigment processing systems.
