RJA Dispersions DPGDA

D3500 series are dispersions in dipropylene glycol diacrylate (DPGDA), CAS number 57472-68-1. These dispersions are to be used in UV-curing ink jet inks. The organic pigments are usually dispersed at 25% of the dispersion. The whites are at a higher loading. The approved dispersions are presented below. A brief description of the dispersion is given along with the viscosity (cps at 25 C) and the mean particle size determined by dynamic light scattering (dls). The values are typical but should not be considered as specifications, The dispersions have passed our 8-week heat stability testing but vehicles, solvents, and additives can interfere with heat stability. If the dispersion is not stable in your system, please contact us to develop a dispersion that will be stable in your system.

We have dispersions with other dispersant packages. The third digit refers to the dispersant system and the fourth digit to the pigment. If you use dispersions of different dispersant systems you will need to confirm that they are compatible with your system.
