Indian Phthalocyanine Green Pigment G7 - Vibrant Color for Paints and Coatings

Indian Phthalocyanine Green Pigment G7 (also known as Pigment Green 7 or Copper Phthalocyanine Green) is a synthetic organic pigment renowned for its exceptional color intensity, lightfastness, and chemical stability. As a fully chlorinated derivative of copper phthalocyanine, this pigment stands out as a cornerstone in the coatings industry, delivering vivid greens that withstand environmental challenges while meeting stringent performance demands.

Unmatched Color Brilliance and Versatility

Pigment G7’s molecular structure, featuring a copper-centered phthalocyanine ring with 16 chlorine substituents, creates a deep, transparent green shade with high tinting strength. Unlike traditional pigments, its planar structure ensures uniform light dispersion, producing a clean, jewel-like tone ideal for automotive, architectural, and industrial coatings. The pigment’s transparency allows it to layer seamlessly with other colors, enabling precise color matching in tints and shades. Its compatibility with both solvent-based and waterborne systems broadens its applicability, from high-gloss automotive finishes to matte architectural paints.

Superior Lightfastness and Weather Resistance

One of Pigment G7’s defining strengths is its resistance to fading under prolonged UV exposure. Tested under rigorous accelerated aging conditions (e.g., ISO 11341 or ASTM G154), it retains over 90% of its original color intensity after 1,000+ hours of exposure. This durability makes it indispensable for exterior coatings, such as automotive refinishes, outdoor furniture finishes, and building facades, where color retention is critical for long-term aesthetics. Its chemical inertness further shields it from degradation caused by pollutants, humidity, or temperature fluctuations.

Chemical and Thermal Stability

Pigment G7’s robust molecular framework grants exceptional resistance to solvents, acids, alkalis, and organic chemicals. In laboratory tests, it withstood 72-hour immersion in common solvents (e.g., toluene, xylene) without discoloration or bleeding. Its thermal stability ensures color consistency up to 300°C (572°F), making it suitable for powder coatings and high-temperature industrial applications. This resilience minimizes formulation adjustments, streamlining production for manufacturers.

Environmental and Safety Compliance

In an era of tightening regulations, Pigment G7 aligns with global standards for safety and sustainability. It contains no heavy metals (e.g., lead, cadmium) or hazardous aromatic amines, adhering to REACH, RoHS, and ASTM F963 requirements. Its low-toxicity profile reduces workplace risks during handling and disposal, while its longevity in coatings reduces the need for frequent repainting, lowering lifecycle environmental impacts.

Applications Across Industries

• Automotive Coatings: Used in basecoats and clearcoats for its high chroma and UV resistance, meeting OEM standards for exterior durability.
• Architectural Paints: Enhances exterior facades and roofing with fade-resistant greens, ideal for tropical or high-UV regions.
• Industrial Coatings: Withstands harsh chemicals in marine, oil/gas, and machinery applications, preserving color integrity in aggressive environments.
• Plastics and Inks: Provides vivid greens for packaging, consumer electronics, and textile printing, with excellent migration resistance.

Formulation Benefits for Manufacturers

Pigment G7’s ease of dispersion simplifies production. It requires minimal milling time in solvent-based systems and can be pre-dispersed into masterbatches for waterborne formulations, reducing energy consumption and batch variability. Its high opacity-to-loading ratio enables cost-effective formulations, as lower pigment concentrations achieve desired color strength.
