Q1: What types of resin systems is Korea FB-707 compatible with?
A: Korea FB-707 demonstrates good compatibility with a broad range of thermoplastic and thermosetting systems, including ABS, PS, PC, PMMA, PVC, and epoxy resins. It is not recommended for high-temperature processing above 260°C or strongly acidic/alkaline environments without prior compatibility testing.
Q2: How does FB-707 perform under UV exposure and outdoor weathering?
A: As a fluorescent pigment, FB-707 delivers strong chromatic intensity under UV illumination but exhibits moderate lightfastness in prolonged direct sunlight. For outdoor applications, stabilization with UV absorbers and HALS additives is strongly advised to extend fluorescence retention.
Q3: Is FB-707 suitable for food-contact or medical-grade applications?
A: Korea FB-707 is intended for industrial and decorative applications only. It is not certified for food-contact, pharmaceutical, or implantable medical use. Customers requiring regulatory compliance must conduct full migration and toxicological assessment per their target market requirements.
Q4: What is the typical dosage range for optimal fluorescence effect?
A: Fluorescence intensity increases with concentration, but excessive loading may cause aggregation or reduce transparency. Dosage generally ranges from 0.1% to 2% by weight depending on the base polymer, desired brightness, and processing method — fine-tuning is recommended during formulation development.
