Q1: What is the primary chemical class of Hostaperm Clariant Blue B2G 03?
A: Hostaperm Blue B2G 03 is a high-performance perylene-based organic pigment, known for its excellent lightfastness, thermal stability, and resistance to migration in demanding polymer applications.
Q2: Is this pigment suitable for use in polyolefin masterbatches?
A: Yes — Hostaperm Blue B2G 03 is widely used in polypropylene and polyethylene masterbatches due to its good dispersion behavior, high heat stability during extrusion, and minimal plate-out tendency under standard processing conditions.
Q3: How does this pigment perform in outdoor applications requiring long-term UV resistance?
A: It exhibits very good to excellent lightfastness and weather resistance, making it suitable for exterior applications such as automotive plastics, construction profiles, and agricultural films where prolonged UV exposure is expected.
Q4: Can Hostaperm Blue B2G 03 be used in food-contact compliant formulations?
A: While the pigment itself is not inherently non-compliant, regulatory approval for food contact depends on final formulation, processing conditions, and applicable regional regulations. Users must verify compliance through qualified testing and consult Clariant’s latest regulatory documentation for permitted applications and restrictions.
Q5: What is the typical dosage range for achieving strong blue shades in engineering thermoplastics?
A: Dosage generally ranges from 0.1% to 2% by weight depending on the polymer matrix, required chroma, opacity requirements, and processing method — with lower concentrations often sufficient due to its high tinting strength and color purity.
