Q1: What types of resin systems is Korea FL-205 compatible with?
A: Korea FL-205 exhibits good compatibility with a wide range of thermoplastic and thermosetting systems, including ABS, PS, PVC, acrylics, polyesters, and epoxy resins. It is not recommended for use in highly polar or strongly acidic media without prior compatibility testing.
Q2: How does FL-205 perform under UV exposure and elevated processing temperatures?
A: FL-205 offers moderate UV stability in opaque formulations but may experience gradual fluorescence intensity reduction under prolonged direct UV exposure. It maintains pigment integrity during standard melt processing (e.g., injection molding, extrusion) up to approximately 220°C for short residence times.
Q3: What is the typical dosage range for achieving strong fluorescent effect?
A: The optimal loading level depends on substrate transparency, desired intensity, and application method, but it is typically used at low concentrations—generally ranging from 0.1% to 2% by weight in the final formulation.
Q4: Is FL-205 suitable for applications requiring regulatory compliance for consumer goods?
A: FL-205 is intended for industrial and non-food-contact applications. For regulated end uses—including toys, cosmetics, or food packaging—formulators must conduct full regulatory assessment based on regional requirements and final product composition.
