Hansen solubility parameters
The Hansen solubility parameters are three-dimensional solubility parameters . They consist of a disperse part from London interactions (δ D ), a part from dipolar interactions (δ P ) and a part for the hydrogen bonds (δ H ):
Hansen solubility parameters play an important role in the paint formulation . Charles M. Hansen developed it in 1967 in his doctoral thesis.
