Q1: What types of resin systems is Korea FL-707 compatible with?
A: Korea FL-707 demonstrates good compatibility with a broad range of thermoplastic and thermosetting systems, including ABS, PS, PVC, acrylics, polyesters, and epoxy resins. Compatibility should always be verified through small-scale formulation trials under actual processing conditions.
Q2: How stable is the fluorescence under UV exposure and thermal processing?
A: Korea FL-707 offers enhanced photostability compared to conventional fluorescent pigments, though prolonged direct UV exposure may gradually reduce intensity over time. It maintains fluorescence integrity during standard melt-processing temperatures up to approximately 220°C for typical residence times, but extended thermal stress above this range may affect performance.
Q3: Is Korea FL-707 suitable for applications requiring regulatory compliance in coatings or plastics?
A: Korea FL-707 is intended for industrial non-food-contact applications such as decorative coatings, signage, and specialty plastics. It is not certified for food-contact, pharmaceutical, or cosmetic use. Regulatory suitability depends on end-use jurisdiction and final formulation — users must conduct their own compliance assessment per applicable local requirements.
Q4: What is the recommended dosage range for optimal fluorescence effect?
A: Optimal loading typically ranges from 0.1% to 2% by weight of the total formulation, depending on substrate transparency, desired chroma intensity, and application method. Lower concentrations are often sufficient in clear matrices, while higher loadings may be needed in opaque or highly pigmented systems — dispersion quality significantly influences final performance.
