Applications of UV Absorber UV-326
UV 326 is a uv absorber of the hydroxyphenyl benzotriazole class, especially suited for polyolefins and cold cured polyesters.
UV 326 exhibits strong absorbance in the 300-400nm region and minimal absorption in the visible region (> 400 nm) of the spectrum.
The recommended levels for normal polyester resins range from 0.2% to 0.5%.
UV 326 is approved in many countries for use in food contact applications.
