SONGSORB® 7120

Technical Datasheet | Supplied by Songwon
2,4-di-tert-butylphenyl-4’-hydroxy-3’,5’-di-tert-butyl benzoate. Acts as a UV absorber. Absorbs ultraviolet radiation and through a reversible chemical rearrangement, dissipates the energy as heat. Provides better initial color than benzotriazoles. Exhibits a synergistic effect in combination with HALS. Can be used in combination with phenolic as well as phosphite antioxidants, and HALS for thermal and light stabilization in outdoor use – i.e. TPO bumper application.

Hansen Solubility Parameters

[16.8, 1.2, 2.6]
?
[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® 7120. A practical determination of these HSP values would provide higher certainty. Learn More.
