>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.

Handing and Safety: 

>In accordance with good industrial practice, handle with care and avoid unnecessary personal contact. Avoid continuous or repetitive breathing of dust. Use only with adequate ventilation.
