Q1: What types of resins and polymers is Korea FB-400 compatible with?
A: Korea FB-400 demonstrates good compatibility with a broad range of thermoplastic and thermosetting systems, including ABS, PS, PVC, acrylics, polyesters, and epoxy-based coatings. It is not recommended for high-temperature processing above 220°C without prior thermal stability evaluation.
Q2: How lightfast is Korea FB-400 under UV exposure?
A: As a fluorescent pigment, FB-400 provides strong initial brightness but exhibits moderate lightfastness. Prolonged direct UV exposure may lead to gradual fluorescence attenuation. For outdoor applications requiring extended durability, it is advised to use UV stabilizers and protective topcoats.
Q3: Can Korea FB-400 be used in food-contact plastics or inks?
A: Korea FB-400 is not certified for direct food contact applications. Its use in packaging or consumer goods must comply with applicable regional regulatory requirements, and formal migration testing and regulatory review are required before commercial deployment.
Q4: What is the typical dosage range for achieving optimal fluorescence intensity?
A: Optimal fluorescence intensity is typically achieved at low concentrations—generally ranging from 0.1% to 2% by weight, depending on the base resin, film thickness, and desired visual effect. Overloading may cause aggregation and reduce transparency or brightness.
