Heubach HEUCODUR Yellow 6R Inorganic Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical composition of HEUCODUR Yellow 6R?

A: HEUCODUR Yellow 6R is a high-performance inorganic pigment based on a complex metal oxide system, specifically engineered for thermal and chemical stability. It does not contain cadmium, lead, or chromium(VI), aligning with modern regulatory expectations for restricted heavy metals.

Q2: Is this pigment suitable for applications requiring high heat resistance, such as engineering plastics processing?

A: Yes — HEUCODUR Yellow 6R is formulated for exceptional thermal stability and is routinely used in high-temperature polymer processing, including polyolefins, polyesters, and engineering thermoplastics processed above 260 °C. Its inorganic nature ensures minimal color shift or degradation under extended thermal stress.

Q3: How does HEUCODUR Yellow 6R compare to organic yellow pigments in terms of lightfastness and weather resistance?

A: As an inorganic pigment, HEUCODUR Yellow 6R offers significantly superior lightfastness, UV stability, and long-term outdoor durability compared to most organic yellows. It maintains consistent hue and opacity even under prolonged exposure to sunlight and atmospheric conditions, making it preferred for demanding exterior applications.

Q4: Can HEUCODUR Yellow 6R be used in food-contact plastics?

A: While HEUCODUR Yellow 6R is manufactured without intentionally added restricted substances and meets general purity requirements for pigments in polymers, formal compliance with food-contact regulations depends on final formulation, migration testing, and regional regulatory assessment. Customers are advised to conduct application-specific validation per applicable local frameworks.

Q5: What is the typical dosage range when incorporating this pigment into plastic compounds?

A: Dosage varies depending on the polymer matrix, desired shade intensity, and processing method, but HEUCODUR Yellow 6R is generally effective at low concentrations — typically ranging from 0.1% to 2% by weight — due to its high tinting strength and excellent dispersion characteristics.
