Q1: What types of resin systems is Korea FB-203 compatible with?
A: Korea FB-203 exhibits good compatibility with a wide range of thermoplastic and thermosetting systems, including ABS, PS, PC, PET, PMMA, and epoxy resins. It is not recommended for use in highly polar or strongly acidic polymer matrices without prior compatibility testing.
Q2: How does FB-203 perform under UV exposure and elevated processing temperatures?
A: FB-203 offers moderate UV stability for short-to-medium term applications but is not designed for prolonged outdoor exposure without protective overcoating or UV stabilizer supplementation. It maintains fluorescence integrity during standard melt processing up to approximately 220°C, though extended residence time above 200°C may lead to gradual intensity reduction.
Q3: Can FB-203 be used in food-contact plastics?
A: Korea FB-203 is not certified for direct food-contact applications. Its use in packaging or containers intended for food, beverage, or pharmaceutical contact requires full regulatory review and third-party compliance verification per applicable regional requirements.
Q4: What is the typical dosage range for achieving strong fluorescent effect?
A: Effective fluorescence is typically achieved at low concentrations—generally ranging from 0.1% to 2% by weight, depending on base resin transparency, desired chroma intensity, and part thickness. Higher loadings may improve brightness but can affect dispersion quality and mechanical properties if not optimized.
