Q1: What types of resin systems is Korea PA-707 compatible with?
A: Korea PA-707 is formulated for compatibility with common thermoplastic and thermosetting resins, including ABS, PS, PC, PMMA, and epoxy-based systems. It demonstrates good dispersion stability in non-polar and moderately polar matrices but may require surface treatment or dispersing aids in highly polar or reactive systems such as polyurethanes or nylon.
Q2: How does PA-707 perform under UV exposure and outdoor weathering?
A: As a fluorescent pigment, PA-707 delivers strong chromatic brightness under UV-A illumination. However, prolonged direct UV exposure—especially in unshielded outdoor applications—may lead to gradual fluorescence attenuation over time. For enhanced durability, it is recommended to combine with UV stabilizers and protective topcoats when used in exterior-grade formulations.
Q3: Is PA-707 suitable for food-contact or pharmaceutical packaging applications?
A: Korea PA-707 is not certified for direct food-contact or pharmaceutical use. It is intended for general industrial and decorative applications where regulatory compliance for ingestion or inhalation is not required. Customers requiring food-safe fluorescent solutions should consult specialized pigments approved under relevant regional frameworks.
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 relative to the base polymer or binder. The exact dosage depends on formulation requirements, substrate opacity, desired brightness level, and processing conditions—higher loadings do not always improve performance and may affect dispersion or mechanical properties.
Q5: Can PA-707 be used in water-based coatings or inks?
A: While PA-707 is supplied as a dry powder pigment, it can be incorporated into water-based systems using appropriate wetting agents and high-shear dispersion techniques. Performance may vary depending on pH, ionic strength, and co-formulants; pre-testing for stability, color consistency, and fluorescence retention is strongly advised before full-scale implementation.
