Characteristics and Uses
This product 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,
 varnish of alcohol and acname, polyurethane, acrylate, expoxnamee etc. Its dosage is 0.1%-0.5%.
Storing and Packing
This product is nontoxic, inflammable, noncroddible and well stable, packed in cardboard drums
