Introduction:
UV-1164 is a new class of UV absorber exhibiting very low volatility and good compatibility with a variety of polymers, co-additives and resin compositions. It is used in the area of engineering resins, the automotive top coat and exterior building, due to a higher resistance to weathering then conventional benzotriazole UV absorber
¡¡
Application:
UV-1164 applications include polyalkylene terephthalates,polycarbonates,modified polyphenylene ether and various high performance plasticsThe usage of UV-1164 is particularly suitable for processing and aging conditions where high loads,low volatility and good compatibility are required.
¡¡
It is very high UV-screen activity that allows the use of lower concentrations than traditional UV absorbers. This may be of particular importance when using UV-1164 in high concentration applications
