| Use | UV-1164 is a hydroxybenzyl triazine-based UV absorber that can absorb ultraviolet light in the wavelength range of 280-380 nanometers, with peak absorption at 293 nanometers and 342 nanometers. It has good compatibility, low volatility, good durability, low migration, good thermal stability, and high absorption efficiency, and also has the characteristics of long-lasting absorption efficiency and non-complexation with metal ions. It is suitable for polyesters, polyamides, polyetheramines, polyformaldehyde, acrylic resins, and ABS resin. It is especially suitable for transparent and semitransparent engineering plastics, PA, PP, PE, PET, and PMMA films, sheets, and plates. |
| Dosage | Recommended dosage: 0.2%-0.4% for polyethylene; 0.15%-0.3% for polycarbonate; 0.1%-0.5% for ABS resin. |
