Q1: What types of resin systems is Korea FB-207 compatible with?
A: Korea FB-207 demonstrates good compatibility with a broad range of thermoplastic and thermosetting systems, including ABS, PS, PVC, acrylics, and certain polyesters. It is not recommended for high-temperature engineering resins such as polyphenylene sulfide (PPS) or polyetherimide (PEI) without prior thermal stability evaluation.
Q2: How does FB-207 perform under UV exposure and outdoor weathering?
A: As a fluorescent pigment, FB-207 delivers strong chromatic brightness under UV-A illumination but exhibits moderate lightfastness in prolonged direct sunlight. For extended outdoor applications, co-stabilization with UV absorbers and HALS is strongly advised to maintain fluorescence intensity and minimize fading.
Q3: What is the typical dosage range for achieving optimal fluorescence effect?
A: Optimal fluorescence intensity is generally achieved at low concentrations—typically ranging from 0.1% to 2% by weight, depending on base resin transparency, film thickness, and desired visual impact. Overloading may lead to aggregation and reduced brightness, so dispersion quality and gradual dosing are critical.
Q4: Is FB-207 suitable for food-contact or pharmaceutical packaging applications?
A: Korea FB-207 is not certified for direct food-contact or pharmaceutical use. It is intended for general industrial, decorative, and non-regulated functional applications. Customers requiring regulatory compliance must conduct full migration and toxicological assessments per applicable jurisdictional requirements.
