Q1: What is the primary chemical nature of Hostafine Green GN 30?
A: Hostafine Green GN 30 is a high-performance, solvent-based pigment paste formulated with a copper phthalocyanine-derived green pigment, dispersed in a proprietary non-volatile carrier system optimized for stability and compatibility in industrial coatings and plastics.
Q2: Is this color paste suitable for use in food-contact applications?
A: Hostafine Green GN 30 is not pre-qualified for direct food-contact applications. Its suitability depends on final formulation, processing conditions, and regulatory review by the end-user — consultation with Clariant’s regulatory team and full migration testing are required before considering such use.
Q3: How should Hostafine Green GN 30 be incorporated into thermoplastic compounds?
A: It is typically added during compounding via side-feed or gravimetric dosing systems. Good dispersion is achieved under standard melt-mixing conditions; pre-drying is not required, but storage under dry, ambient conditions is recommended to maintain rheological consistency.
Q4: Can this paste be used in water-based systems?
A: Hostafine Green GN 30 is specifically designed for solvent-borne and melt-processable systems. It is not inherently compatible with water-based formulations without significant reformulation support; alternative aqueous dispersions from the Hostafine portfolio may be more appropriate.
