| Questions And Answer | Back Directory | [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.
Detailed information on handling and any precautions to be observed in the use of the product(s) described in this leaflet can be found in our relevant health and safety information sheet.
