Characteristics and Uses:

UV-531 is a light stabilizer with good performance, capable of absorbing the UV radiation of 240-340   nm   wavelength    with   the    characteristics    of   light    color,    nontoxic   ,   good compatibility,small mobility, easy processing etc. It can protect the polymer to its maximum extent, helps to reduce the color. It can also delay the yellowing and obstacle the loss of its physical function. It is widely applied to PE,PVC,PP,PS,PC organic glass, polypropylene fiber, ethylene-vinyl acetate etc. Moreover, it has very good light-stability effect on drying phenol aldehyde, varnis of alcohol and acname, polyurethane, acrylate, expoxnamee etc. Its dosage is 0.3%~0.5%.

 

Precaution:  No  toxicity  kept  away  from  moisture  and  fire  in  transportation;  stored  and transported  as  common   chemicals  with   relatively  good  stability,  kept  in  a  well-closed, light-resistant, dry and cool place.
