Q1: What is Sinosorb® UV-1600 and what is its chemical nature?
A: Sinosorb® UV-1600 (under CAS 204583-39-1) is an ultra-high performance, crystalline ultraviolet absorber belonging to the elite class of biphenyl-substituted hydroxyphenyl-triazines (HPT). Chemically designated as 2-[4,6-di(biphenyl-4-yl)-1,3,5-triazin-2-yl]-5-[(2-ethylhexyl)oxy]phenol, it is engineered for advanced industrial applications requiring extreme photostability, high extinction coefficients, and absolute resistance to thermal degradation.
Q2: What are the main common uses of UV Absorber 1600 in the chemical industry?
A: The common uses of UV Absorber 1600 are focused entirely on high-stakes, high-temperature polymer processing and thin-film optical systems. Its main uses include serving as the premier light-stabilizing additive in optical PET films, co-extruded polycarbonate (PC) roofing sheets, high-end automotive OEM protective clearcoats, and long-life photovoltaic solar panels. It is universally selected by chemical engineers who require ultimate weatherability in thin layers without any structural migration.
