UV-770 can be dissolved in such organic solvent such as benzol, touene, phenyethene, etc. It can not be dissolved in water. It can be easily dissolved in som kinds of resin, and it is not sensitive to metal Ions. Under alkalinity, as low volatile, it is not turned int yellow, ca absorb the ultraviolet ray of 270-380nm wavelength effectively. When used with antioxidants, it has cooperative effect. With lower position, it is considered as the world's sagest plastic accretion.
