Hansen Solubility Parameters

[16.7, 10.8, 6.6]
[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 BASF 4-Hydroxybutyl Acrylate (4-HBA). A practical determination of these HSP values would provide higher certainty. Learn More.
