PRODUCT FEATURES AND APPLICATIONS
* UV312 is an ultraviolet light absorber of the oxanilide class, which imparts outstanding lightstability to plastics and other organic substrates. Particularly it is recommended for rigid and flexiblePVC and polyesters
* UV 312is a highly effective light stabilizer for a variety of plastics and other organic substrates
including unsaturated polyesters, PVC(flexible and rigid) and PVC plastisol.
* UV 312 can also be used in other substrates like polyurethanes, polyamides,PMMA, polycarbonates and cellulose esters.
*Features strong UV absorption, excellent compatibility in a wide variety of substrates and low volatility. It protects polymers as well as organic pigments from UV radiation, helping topreserve the original appearance and physical integrity of molded articles, films, sheets, and fibersduring outdoor weathering.
Beneath the performance as light stabilizer, several advantages can beencountered with UV312
- It is a white product, color and transparency are therefore not changed.
- It is low volatile and thermally stable.
- It presents an excellent chemical resistance and is not reactive with alkalines.
- It brings additional thermal stability in polyamides.
- It absorbs at low wavelengths, it can be combined with optical brighteners.
* UV 312 is also suitable for use in powder coatings and solvent-borne coatings for automotive,
industrial, and architectural applications.
