Q1: What is the primary chemical class and typical hue of Heliogen K7090?
A: Heliogen K7090 is a high-performance perylene-based organic pigment, delivering a clean, bluish red shade with excellent brightness and strong tinting strength.
Q2: Is Heliogen K7090 suitable for use in automotive coatings?
A: Yes — it is widely used in high-end automotive refinish and OEM basecoat systems due to its outstanding lightfastness, thermal stability up to typical curing temperatures, and resistance to common solvents and acid/base environments encountered during coating processing.
Q3: How does Heliogen K7090 perform in polymer applications such as polyolefins or engineering plastics?
A: It demonstrates good dispersibility and thermal stability in polyolefins and many engineering thermoplastics, enabling consistent coloration without significant degradation during melt processing — dosage typically depends on formulation requirements but generally ranges from 0.1% to 2% by weight.
Q4: Can Heliogen K7090 be used in water-based systems?
A: Yes — when properly dispersed using suitable surfactants or polymeric dispersants, it performs well in aqueous architectural paints, industrial waterborne coatings, and inkjet inks requiring high chroma and durability.
