Q1: What is the primary chemical class and typical hue profile of GNX 7?
A: GNX 7 is a copper phthalocyanine-based pigment, delivering a bright, clean blue shade with strong greenish undertones—characteristic of high-performance α-phase phthalocyanine pigments.
Q2: Is GNX 7 suitable for use in food-contact plastics?
A: GNX 7 is designed for industrial applications and is not pre-approved for direct food-contact use. Regulatory compliance must be verified case-by-case based on final formulation, processing conditions, and applicable regional requirements.
Q3: How does GNX 7 perform in terms of thermal stability during polymer processing?
A: GNX 7 exhibits excellent thermal stability, maintaining color integrity under standard polyolefin and engineering plastic processing conditions—including extrusion and injection molding at temperatures up to approximately 280 °C.
Q4: What dispersion methods are recommended for optimal performance in masterbatches?
A: For consistent color development and minimal agglomeration, high-shear compounding—such as twin-screw extrusion—is strongly recommended. Pre-wetting or use of compatible dispersing aids may further enhance pigment distribution in non-polar polymer systems.
Q5: Can GNX 7 be used alongside other organic pigments in multi-pigment systems?
A: Yes—GNX 7 demonstrates good compatibility with many common organic pigments and shows no significant adverse interactions under typical compounding conditions. However, compatibility testing in the final application matrix is advised to confirm color stability and absence of flocculation.
