UV-329

Light Stabilizer

 

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

 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. UV-329 typical use levels from 0.10 to 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, and other functional stabilizers and additives.

UV-329 in combination with HALS is particularly noteworthy in that a synergistic performance is often observed.
