Questions And Answer

• Characterization

  UV-329 is an ultraviolet light absorber (UVA) of the hydroxyphenyl benzotriazole class, which is used as a light stabilizer for plastics and other organic substrates.;

• Physical Properties

  ;

• Applications

  UV-329 is an effective light stabilizer for a variety of plastics and other organic substrates.;

• Features/benefits

  UV-329 protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering.;

• Product forms

  UV-329    Slightly yellow powder
  UV-329 FL     Slightly yellow, rodlike granules ;

• Guidelines for use

  The use levels of UV-329 range between 0.1 and 1.0 %, depending on substrate and performance requirements of the final application. The product can be used alone or in combination with other additives such as light stabilizers (hindered amines), antioxidants (hindered phenols, phosphites, thiosynergists, hydroxylamines), and other functional stabilizers and additives. The use of UV-329 in combination with hindered amine light stabilizers is particularly noteworthy in that a synergistic performance is often observed. Performance data of UV-329 alone or in combination with other additives are available in selected substrates.;

• Handling & Safety

  UV-329 exhibits a very low order of oral toxicity and does not present any abnormal problems in its handling or general use.
