SONGSORB® 3290

Technical Datasheet | Supplied by Songwon
2-(2H-benzotriazol-2-yl)-4-(1,1,3,3-tetramethylbutyl)phenol. Acts as a strong absorber of ultraviolet radiation in the 300-400nm region. Has a high degree of photostability - photochemical energy absorbed in ultraviolet region is dissipated as thermal energy. Provides effective light stabilization as well as prevents the yellowing and degradation of polymers such as polycarbonate, unsaturated polyesters, acrylics. Protects the polymers from UV radiation, helping to preserving the original appearance as well as physical integrity of molded articles, films, sheets and fibers during outdoor weathering. Can be used in combination with phenolic as well as phosphite antioxidants, and optimize performance in outdoor use.

Hansen Solubility Parameters

[18.3, 4.8, 4.6]
?
[δD - Dispersion force interactions, δP - Polar force interactions, δH - Hydrogen bond force interactions]

Please note, these HSP values are estimations. It is based upon the “like seeks like” principle. It splits an ingredients interactions into three parameters; δD (Dispersion force interactions), δP (Polar forces interactions) and δH (Hydrogen bond force interactions). Hansen Solubility Parameters can help you find a wide range of products that are predicted to be compatible with SONGSORB® 3290. A practical determination of these HSP values would provide higher certainty. Learn More.
