Q1: What types of resin systems is FL-605 compatible with?
A: FL-605 demonstrates good compatibility with a broad range of thermoplastic and thermosetting systems, including ABS, PS, PVC, acrylics, and unsaturated polyesters. It is not recommended for high-temperature engineering resins like PEEK or polyimides without prior thermal stability evaluation.
Q2: How does FL-605 perform under UV exposure and outdoor weathering?
A: FL-605 offers moderate UV resistance in protected applications but is not inherently UV-stabilized. For extended outdoor use, co-addition of HALS-type light stabilizers and UV absorbers is strongly advised to maintain fluorescence intensity and minimize fading.
Q3: What is the typical dosage range for achieving strong fluorescent effect?
A: FL-605 is highly efficient and typically used at low concentrations—generally ranging from 0.1% to 2% by weight—depending on the base polymer transparency, desired chroma, and processing method. Optimal loading should be determined empirically for each formulation.
Q4: Can FL-605 be used in food-contact plastics?
A: FL-605 is intended for industrial and decorative applications only. It is not certified for direct or indirect food contact, and its regulatory status for such uses has not been established. Customers requiring food-safe fluorescent solutions must consult applicable regional regulations and pursue specifically approved alternatives.
