Features and Benefits

High molecular weight wetting and dispersing agent for solvent ink-jet. The additive can improve the wetting process of pigments, and at the same time, through good steric stability of pigments,

Improve the appearance performance of final ink-jet (hue intensity, luster, fog shadow, transparency). It can reduce the viscosity of color paste and final ink-jet, and avoid thixotropic

Elephants. It can also realize long-term storage stability and no change in viscosity.

VOK?- Disper 9133 can make pigment particles have an equal amount of isotropic charge, thus avoiding flocculation caused by uneven charge of pigment particles. Due to the good pigment flocculation effect, the product can make the pigment dispersion particle size very small, and the particle size distribution is narrow, thus shortening the ink jet filtering time.

Recommended use

VOK?- Disper 9133 is suitable for various types of solvent inkjet, especially for the dispersion of carbon black pigment.

Recommended dosage

40-90% auxiliary agent (supply form) to carbon black pigment meter.

The above recommended dosage is for reference, and good dosage shall be determined through a series of tests.

Adding method and processing guidance

Wetting dispersants should normally be added to the abrasive, which is the only way to make them fully effective. Pre mix the resin and solvent components in the abrasive, and then slowly add the auxiliary agent under stirring. The pigment can be added only after the auxiliary agent is completely dispersed and uniform.
