Q1: What is the primary chemical class of Hostaperm Green GNX-C?
A: Hostaperm Green GNX-C is a high-performance perylene-based organic pigment, offering excellent lightfastness, thermal stability, and weather resistance typical of premium-grade perylene derivatives.
Q2: Is this pigment suitable for food-contact plastics?
A: Hostaperm Green GNX-C is not pre-approved for direct food-contact applications under major global regulatory frameworks. Its use in food-contact materials requires full formulation-level compliance assessment by the end-user, including migration testing and regulatory review per applicable jurisdiction.
Q3: How does GNX-C perform in high-temperature polymer processing?
A: This pigment demonstrates good thermal stability and is commonly used in engineering thermoplastics processed at temperatures up to approximately 300 °C, such as polyamide and polyesters—provided residence time and shear conditions are controlled to preserve dispersion integrity.
Q4: What is the recommended dosage range in standard plastic coloration?
A: Dosage depends on the desired shade strength and base polymer, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—to achieve strong green hues with optimal transparency or opacity, depending on application requirements.
Q5: Can GNX-C be used in water-based coatings or inks?
A: While primarily developed for plastics, GNX-C can be formulated into aqueous systems using appropriate dispersants and stabilization technologies; however, performance—especially in terms of gloss, rheology, and long-term storage stability—requires tailored dispersion development and compatibility testing.
