Q1: What types of resin systems is FB-805 compatible with?
A: Korea FB-805 exhibits good compatibility with a wide range of thermoplastic and thermosetting systems, including ABS, PS, PC, PVC, acrylics, and epoxy resins. It is not recommended for high-temperature processing above 260°C or strongly acidic/alkaline environments without prior compatibility testing.
Q2: How stable is the fluorescence under UV exposure and thermal processing?
A: FB-805 offers moderate photostability under typical indoor UV conditions but may experience gradual intensity reduction under prolonged direct sunlight or intense UV-A/B irradiation. Thermal stability supports standard injection molding and extrusion processes, though extended residence time at elevated temperatures should be minimized to preserve brightness.
Q3: Can FB-805 be used in applications requiring regulatory compliance for food contact or toys?
A: FB-805 is intended for general industrial and decorative applications. It is not pre-certified for food-contact or toy safety regulations (e.g., FDA 21 CFR, EN71-3, or LFGB). Customers must conduct full regulatory validation—including migration testing and formulation-specific assessments—prior to use in regulated end products.
Q4: What is the typical dosage range for achieving strong fluorescent effect?
A: The optimal loading level depends on substrate transparency, desired intensity, and processing method. FB-805 is typically used at low concentrations—generally ranging from 0.1% to 2% by weight—and often achieves vivid effects at the lower end of this range in clear matrices.
