Description
Basf Heliogen Blue K 7090: Heliogen Blue K 7090 is a chlorinated copper phthalocyanine pigment, which is applicable to fields such as children's toys and food packaging materials (subject to compliance with relevant safety standards and regulatory requirements). At the same time, it is also widely used in coloring of various plastics, such as PVC, PUR, LD-PE, HD-PE, etc., as well as in offset printing, gravure printing, etc., to enhance the coloring power and vividness of inks.

Basf Heliogen Blue K 7090 – Frequently Asked Questions (FAQ)
Q1: What is the primary chemical class and pigment type of Heliogen Blue K 7090?
A: Heliogen Blue K 7090 is a high-performance copper phthalocyanine (CuPc) pigment, classified as an organic pigment with excellent crystalline stability and strong blue-green hue characteristics.
Q2: Is this pigment suitable for use in food-contact plastics or packaging applications?
A: Heliogen Blue K 7090 is not certified for direct food-contact applications. It is intended for industrial coatings, general-purpose plastics, and non-regulated decorative uses where regulatory compliance for ingestion or migration is not required.
Q3: How does its weathering and lightfastness performance compare to standard phthalocyanine blues?
A: As a stabilized grade, Heliogen Blue K 7090 delivers enhanced lightfastness and weather resistance compared to basic CuPc pigments—particularly in outdoor-exposed coatings and polyolefin applications—due to optimized particle surface treatment and crystal phase control.
Q4: What dispersion methods are recommended for optimal color development in solvent-based systems?
A: For solvent-based coatings and inks, high-shear dispersing using appropriate wetting agents and stabilizers is recommended. Pre-dispersed pastes or let-down formulations often yield superior gloss, transparency, and batch-to-batch consistency versus dry-powder incorporation.
Q5: Can it be used in water-based systems without modification?
A: While inherently hydrophobic, Heliogen Blue K 7090 can be formulated into aqueous systems using compatible surfactants or by selecting pre-treated or surface-modified versions. Direct use of the standard grade may require additional stabilization to prevent agglomeration and ensure colloidal stability.
