Clariant Hostaperm Red E3B Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical class and pigment type of Hostaperm Red E3B?

A: Hostaperm Red E3B is a high-performance perylene-based organic pigment, classified under the Colour Index as PR179. It belongs to the family of polycyclic pigments known for exceptional thermal stability, lightfastness, and resistance to migration in demanding polymer applications.

Q2: In which polymer systems is Hostaperm Red E3B most commonly used, and what processing conditions can it withstand?

A: This pigment is widely employed in engineering thermoplastics such as polyamide (PA6, PA66), polybutylene terephthalate (PBT), and polyethylene terephthalate (PET), especially where high-temperature melt processing (up to ~300 °C) and long residence times are required. It demonstrates excellent dispersion stability and minimal thermal degradation under these conditions.

Q3: Is Hostaperm Red E3B suitable for food-contact or regulatory-sensitive applications?

A: Hostaperm Red E3B is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial uses, including automotive interior parts, technical components, and decorative exterior applications where high durability and color consistency are critical.

Q4: How does Hostaperm Red E3B perform with respect to weathering and UV resistance?

A: As a perylene pigment, Hostaperm Red E3B offers outstanding outdoor durability and UV resistance—significantly superior to many azo-based reds. When properly formulated and stabilized in compatible polymer matrices, it maintains strong chroma and minimal fading even after extended exposure to sunlight and climatic stress.

Q5: What is the typical dosage range for Hostaperm Red E3B in polymer masterbatches?

A: Dosage depends on the desired shade strength and final application requirements, but it is typically used at low concentrations in masterbatch formulations—generally ranging from 0.1% to 2% by weight—due to its high tinting strength and efficient color development in the host polymer.
