Product features and applications
1、UV326 is an ultraviolet absorber for 270-380nm, with good light stabilization effect - it converts ultraviolet rays into heat energy through photochemical action.
2、UV326 This product has more effective absorption of long-wavelength bands, good compatibility with polyolefins, low volatile matter, and inhibits the ionization of phenol groups.
3. UV326 has good alkali resistance and will not cause color changes due to metal. Due to its higher ionization constant, metal driers and catalysts have less impact on it.
