UV-329 Chemical Properties,Usage,Production
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.
Description
The ultraviolet absorber UV-329 is a highly effective anti-aging additive with excellent performance. It is soluble in benzene, styrene Chemicalbook, dichloromethane and cyclohexane, slightly soluble in alcohols, insoluble in water; it can effectively absorb 270- 380 nanometer ultraviolet light; non-flammable, non-explosive, non-toxic, safe and harmless to use.
