The use of Hansen Solubility Parameters (HSP) in the development of inkjet inks
ChemStream uses Hansen Solubility Parameters in the development of inkjet inks. This lecture will demonstrate some different approaches of Hansen to successfully obtain ink stability, process performance and ink-substrate interactions. The Hansen Solubility Parameters position each molecule in the 3-dimensional ‘space of solubility’ based on 3 main characteristics: a dispersive component (D), a polar component (P), and a hydrogen bonding component (H). A solubility sphere can be defined, for each of the molecules, from which the radius is a measure of its solubility. These parameters are thus applied in the inkjet ink development process at ChemStream in order to improve nano-dispersion stability, material compatibility, ink-media interactions etc.
