UBEDISP® hyperdispersants are advanced bio-based additives designed to improve the dispersion of titanium dioxide (TiO2) in UV curable inkjet inks, providing high performance in your dispersion while meeting sustainability. These hyperdispersants allow high solid content, reduced viscosity, thermal stability, and resistance to sedimentation.
Titanium dioxide is a widely used white pigment known for its excellent whiteness, brightness, and opacity. However, its large particle size and high density are challenging in low-viscosity systems, as the particles tend to settle, especially in white UV inkjet inks that require high pigmentation levels for adequate opacity.
Dispersants are crucial in UV inkjet ink production, ensuring that pigments are finely dispersed within a complex mixture of reactive monomers, oligomers, and other additives. UBEDISP® hyperdispersants are particularly effective in reducing inter-particle interactions, improving ink stability and performance.
These hyperdispersants significantly lower the viscosity of TiO2 dispersions, essential for efficient inkjet ink production. They prevent TiO2 particle re-agglomeration, maintaining small particle sizes and low viscosity, which are vital for optimal ink performance. UBEDISP® product line achieves remarkable viscosity reductions in high-solid-content dispersions.
In summary, UBEDISP® bio-based hyperdispersants enable the production of high-quality, stable UV inkjet inks with higher TiO2 solid content, making them ideal for formulating sustainable white UV inkjet inks. If you want to know more about this, download our case study!
