Q1: What types of resin systems is Korea FB-305 compatible with?
A: Korea FB-305 exhibits good compatibility with a wide range of thermoplastic and thermosetting systems, including ABS, PS, PC, PVC, acrylics, and unsaturated polyesters. It is not recommended for high-temperature engineering resins requiring prolonged exposure above 260°C without prior thermal stability evaluation.
Q2: How does FB-305 perform under UV exposure and outdoor weathering?
A: As a fluorescent pigment, FB-305 delivers strong chromatic intensity under UV-A illumination but has inherently limited long-term photostability. For outdoor applications, it should be used with appropriate UV stabilizers and protective topcoats to mitigate fading and fluorescence decay.
Q3: Is FB-305 suitable for food-contact or pharmaceutical packaging applications?
A: Korea FB-305 is not certified for direct food contact or pharmaceutical use. It is intended for industrial, decorative, and non-regulated functional applications only. Regulatory compliance must be verified independently per jurisdiction and end-use requirement.
Q4: What is the typical dosage range for achieving optimal fluorescence in plastic masterbatches?
A: Dosage depends on base polymer transparency, desired intensity, and processing conditions, but FB-305 is typically used at low concentrations — generally ranging from 0.1% to 2% by weight in masterbatch formulations.
