Advantage:
- UV absorber UV-120 is a benzene acid ester type ultraviolet absorber, possessing dual functions of light stabilizer and antioxidant. It can absorb UVB and UVC, with the absorption peak at 265 nm.
- It has the characteristics of high temperature resistance, resistance to extraction, low volatility, and low migration. It is suitable for use in PC, PET, PBT, PMMA, coatings, and fabrics.
- It is a UV protection finishing agent for cotton, linen, silk, wool, nylon and other fabrics. The active groups in the molecular structure can react with the hydroxyl groups of cellulose fibers and the amine bonds of polyamide fibers.
- It has excellent light resistance, improving sunfastness, dye fastness and water wash fastness. The general dosage is 0.1-0.5%.
Applications:
Used in Polypropylene, Polyethylene, TPO, PVC, EVA, unsaturated Polyester ABS, AS, etc.
