Q1: What types of resin systems is Korea FP Higt-20 compatible with?
A: Korea FP Higt-20 exhibits 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 trials due to formulation-specific interactions.
Q2: How does this pigment perform under UV exposure and outdoor weathering?
A: Korea FP Higt-20 delivers strong initial fluorescence and moderate UV resistance. For extended outdoor applications, it is recommended to use alongside UV stabilizers and protective topcoats, as prolonged UV exposure may gradually reduce fluorescent intensity over time.
Q3: Is Korea FP Higt-20 suitable for food-contact or medical-grade applications?
A: Korea FP Higt-20 is not certified for direct food contact or implantable medical use. It is intended for general industrial, decorative, and functional coloring applications where regulatory compliance is determined by the final formulated product and end-use conditions.
Q4: What is the typical dosage range for achieving optimal fluorescence in plastics?
A: Optimal dosage generally ranges from 0.1% to 2% by weight, depending on the base polymer, desired chroma intensity, and processing method. Higher loadings may improve brightness but can impact dispersion quality and mechanical properties—pre-dispersed masterbatches are often preferred for consistent results.
