Tinuvin® 329

Technical Datasheet | Supplied by BASF
Tinuvin® 329 by BASF is chemically 2 Phenol, 2-(2H-benzotriazol-2-yl)-4-(1, 1, 3, 3-tetramethylbutyl) grade. It acts as a UV absorber belonging to hydroxyphenyl benzotriazole class. It is an effective light stabilizer for a variety of plastics and other organic substrates. Protects polymers from UV radiation, helping to preserve the original appearance and physical integrity of molded articles, films, sheets, and fibers during outdoor weathering. Use levels of Tinuvin® 329 ranges between 0.1 and 1.0%, depending on substrate and performance requirements of the final application.

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 Tinuvin® 329. A practical determination of these HSP values would provide higher certainty. Learn More.
