Q1: What is the primary chemical composition of HEUCODUR Yellow G9064?
A: HEUCODUR Yellow G9064 is a high-performance inorganic yellow pigment based on a stabilized lead chromate–molybdate solid solution, engineered for exceptional thermal stability and lightfastness in demanding industrial applications.
Q2: Is this pigment suitable for use in plastics processing at elevated temperatures?
A: Yes — HEUCODUR Yellow G9064 is specifically designed for high-temperature polymer processing, including injection molding and extrusion of engineering thermoplastics, where it maintains color integrity without significant degradation or gas evolution.
Q3: How does this pigment perform in terms of weather resistance and UV stability?
A: As a member of the HEUCODUR series, G9064 delivers outstanding outdoor durability and UV resistance, making it well-suited for long-term exterior applications such as automotive coatings, architectural finishes, and durable plastic components exposed to sunlight.
Q4: Can HEUCODUR Yellow G9064 be used in food-contact plastics?
A: This pigment is not intended for direct food-contact applications. Its formulation contains regulated elements, and compliance with food-contact regulations requires case-specific evaluation by qualified regulatory experts and testing under applicable regional frameworks.
Q5: What is the typical dosage range when incorporating G9064 into polymer systems?
A: Dosage depends on the required color strength and opacity, but it is generally used at low concentrations — typically ranging from 0.1% to 2% by weight in most thermoplastic and thermoset formulations.
