WinBLEND Solubility Parameters


WinBLEND - Surface Coatings Formulation & Optimization Software

Solubility Parameters

Much of the solubility parameter data for solvents may not be easily obtained. Below is a table showing evaporation rate and solubility parameters for many common solvents as well as table showing some Hansen solubility parameters for polymers.

Note that the units shown are MPa1/2 (SI units) but some older publications may show units as cal1/2cm-3/2. To convert from the old units to SI units simply multiply by 2.0455. It doesn't matter which units are used in WinBLEND so long as the same units are used throughout the program.
