Features and advantages:

Due to its balanced polarity and 100% active ingredients, VOK ®- Disper 2013 can achieve good pigment dispersion stability, especially in 100% UV curing system, and is particularly effective for organic pigments and carbon black. In the above dispersion process, VOK ®- Disper 2013 has shown excellent and effective viscosity reduction while eliminating thixotropy of flow behavior. Use VOK ®- The long-term storage stability of printing ink in Disper 2013 has also been improved. The highly deflocculating property of the wetting and dispersing agent makes it suitable for printing ink with superior appearance performance, especially for improving color strength and transparency.
