Q1: What types of resin systems is Korea FL-400 compatible with?
A: Korea FL-400 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 preliminary dispersion and stability testing in the target formulation.
Q2: How does FL-400 perform under UV exposure and elevated processing temperatures?
A: FL-400 is engineered for enhanced thermal stability during standard polymer processing (e.g., injection molding, extrusion), but prolonged exposure to temperatures above 220°C may gradually reduce fluorescence intensity. Its UV resistance is moderate; long-term outdoor applications typically require co-stabilization with UV absorbers or HALS for optimal retention of brightness.
Q3: What is the recommended method for dispersing FL-400 in polymer melts or liquid coatings?
A: For optimal dispersion and fluorescence uniformity, pre-mixing FL-400 with a carrier resin or low-viscosity solvent (e.g., aromatic hydrocarbons or ketones for coatings) is advised. In melt processing, masterbatch preparation using high-shear compounding ensures consistent distribution. Avoid excessive shear or extended residence time at peak temperature to preserve pigment integrity.
Q4: Is FL-400 suitable for applications requiring regulatory compliance for indirect food contact?
A: FL-400 is not certified for direct or indirect food-contact applications under major global regulatory frameworks (e.g., FDA 21 CFR, EU Plastics Regulation). It is intended for non-food industrial, decorative, and functional applications where regulatory approval for food contact is not required.
Q5: What is the typical dosage range for achieving strong fluorescent effects?
A: Effective fluorescence is generally achieved at low concentrations, typically ranging from 0.1% to 2% by weight relative to the base polymer or medium. The optimal dosage depends on substrate transparency, desired chroma intensity, and application method — pilot trials are recommended to balance performance, cost, and optical clarity.
