The Kinsotech UV-312 is white crystalline powder, low volatility, excellent thermal stability. Melting point: 124-127℃; Boiling point: > 400℃; Density: 1.216g/cm3; Vapor pressure: Water solubility: 300μg/L; Transmittance: (%) 425nm, ≥95%; 500nm, ≥97%.
The Kinsotech UV-312 exhibits strong absorption in the UV-B spectrum, making it advisable to utilize it in conjunction with fluorescent whitening agents and UV crosslinking systems.
Performance advantages:
1. UV-312 remains inert when interacting with metal ions present from catalyst residues, fillers, and surfaces, ensuring that the color of the plastic it protects is not adversely affected by these metal ions;
2. This product demonstrates excellent synergistic effects and can be effectively combined with other stabilizers such as blocked amine series light stabilizers and benzoate ultraviolet absorbers, thereby providing long-term protection for polycarbonate (PC) and polyethylene terephthalate (PET);
3. Its broad absorption range allows for effective capture of low-wavelength UV-B radiation.
The Kinsotech UV-312 is widely utilized in various applications including polyamide (PA), PET, PC, PVC, acrylates, alkyd resins, polyurethane (PU), among others. Additionally, it is suitable for food contact materials as well as powder coatings, solvent-based coatings, automotive paints, industrial coatings, and architectural paints.
