Clariant Hostaperm Blue BT-627-D Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical class and pigment type of Hostaperm Blue BT-627-D?

A: Hostaperm Blue BT-627-D is a high-performance perylene-based organic pigment, classified under the Pigment Blue 29 (PB29) series. It exhibits excellent crystallinity and molecular stability, contributing to its strong tinting strength and thermal robustness.

Q2: In which polymer systems is this pigment typically processed, and what are key processing considerations?

A: It is widely used in engineering thermoplastics such as polyamide (PA6, PA66), polybutylene terephthalate (PBT), and polyphenylene sulfide (PPS). Due to its high thermal stability, it withstands melt processing temperatures up to approximately 300 °C. Good dispersion—achieved via high-shear compounding or masterbatch dilution—is essential to maximize color development and avoid agglomeration.

Q3: How does Hostaperm Blue BT-627-D perform regarding lightfastness and weather resistance?

A: This pigment delivers outstanding lightfastness (typically rated ≥7–8 on the ISO 105-B02 scale) and excellent resistance to atmospheric conditions, including UV exposure and humidity. Its performance remains consistent in both indoor and demanding outdoor applications when properly formulated and dispersed.

Q4: Is Hostaperm Blue BT-627-D suitable for food-contact or regulatory-sensitive applications?

A: While not specifically certified for direct food contact, Hostaperm Blue BT-627-D is manufactured under Clariant’s strict quality management system and complies with general industry requirements for non-food-contact plastic articles. Regulatory suitability depends on final formulation, migration behavior, and applicable regional frameworks—consult Clariant’s regulatory documentation and conduct application-specific compliance testing.

Q5: What is the typical dosage range for optimal coloration in engineering plastics?

A: Dosage varies depending on the desired shade depth, polymer matrix, and processing method, but it is generally used at low concentrations—typically ranging from 0.1% to 2% by weight in the final compound. For most standard blue shades in polyamide or PBT, effective loading falls within the lower half of this range.
