Clariant Hostaperm Blue BT-617-D Pigment – Frequently Asked Questions (FAQ)

Q1: What is the primary chemical class and pigment type of Hostaperm Blue BT-617-D?

A: Hostaperm Blue BT-617-D is a high-performance perylene-based organic pigment, classified under the Pigment Blue 29 (PB29) series. It belongs to the perylene diimide family, known for exceptional lightfastness, thermal stability, and resistance to migration in demanding polymer systems.

Q2: In which polymer matrices is this pigment most commonly processed and stabilized?

A: Hostaperm Blue BT-617-D demonstrates excellent compatibility and dispersion stability in high-temperature engineering thermoplastics, particularly polyamide (PA6, PA66), polybutylene terephthalate (PBT), and polyphenylene sulfide (PPS). Its thermal stability supports melt processing up to approximately 300 °C without significant degradation.

Q3: Is this pigment suitable for applications requiring food contact compliance?

A: Hostaperm Blue BT-617-D is not pre-approved for direct food contact applications under major regulatory frameworks (e.g., FDA 21 CFR or EU Plastics Regulation). Its use in food-contact articles requires full formulation-level evaluation and approval by the relevant regulatory authority, as pigment performance and compliance depend on final matrix, processing conditions, and intended exposure scenario.

Q4: How does its weathering performance compare to conventional phthalocyanine blues in outdoor applications?

A: Due to its perylene backbone, Hostaperm Blue BT-617-D offers significantly superior UV resistance and long-term color retention compared to standard copper phthalocyanine pigments (e.g., PB15:3), especially in unpigmented or lightly stabilized polyolefin and acrylic coatings exposed to continuous outdoor weathering.

Q5: What is the typical dosage range when used in engineering plastics?

A: Dosage depends on the required shade strength and opacity, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in the final polymer compound—to achieve deep, clean blue hues with optimal dispersion and minimal impact on mechanical properties.
