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.
