Clariant Novoperm Red BN Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical class and typical application field for Novoperm Red BN?

A: Novoperm Red BN is a high-performance perylene-based organic pigment, widely used in demanding applications such as automotive coatings, industrial finishes, and high-gloss plastics where excellent lightfastness, thermal stability, and color strength are required.

Q2: Is Novoperm Red BN suitable for use in food-contact plastics?

A: Novoperm Red BN is not approved for direct food-contact applications under major global regulatory frameworks. It is intended for non-food-contact industrial and decorative uses. For food-contact systems, consult Clariant’s portfolio of certified pigments and obtain full regulatory documentation prior to use.

Q3: How does Novoperm Red BN perform in terms of heat stability during polymer processing?

A: This pigment exhibits very good thermal stability, typically withstanding processing temperatures up to 280–300 °C for short durations—making it suitable for engineering thermoplastics like polyamide, polycarbonate, and ABS, provided dispersion conditions are optimized.

Q4: What are the recommended dispersion methods for achieving optimal color development?

A: Optimal performance is achieved through high-shear dispersion using appropriate equipment (e.g., twin-screw extruders or bead mills), often with compatible dispersants or carrier resins. Pre-dispersed paste or masterbatch forms are also commonly used to ensure uniformity and reduce handling variability.

Q5: Can Novoperm Red BN be used in water-based systems?

A: While primarily designed for solvent-based and high-temperature melt applications, Novoperm Red BN can be formulated into aqueous systems using specialized surfactant-stabilized dispersions—but performance may vary depending on pH, ionic strength, and binder compatibility. Technical support from Clariant is recommended for water-based development.
