Application
:
   

>UV 326 is a UV absorber of the hydroxyphenyl benzotriazole class, especially suited for polyolefins and cold cured polyesters. Used as  Tinuvin 326, Uvinul 3026 equivalent.

>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. Prevent contamination of the environment. Avoid dust formation and ignition sources. When stored, avoid the rain, moisture and sunshine.
