DISPERBYK-2157 – VOC- and solvent-free wetting and dispersing additive for non-polar systems
DISPERBYK-2157 is a VOC- and solvent-free wetting and dispersing additive for non-polar solvent-borne and solvent-free inkjet inks, printing inks, protective and architectural coatings as well as PVC plastisols. The additive is excellent compatible with solvents, like paraffins, isoparaffins, vegetable oils, mineral oils or plasticizers. DISPERBYK-2157 is recommended for all kinds of pigments and greatly improves optical properties such a color strength, transparency and gloss. In inks and coatings applications DISPERBYK-2157 provides a strong reduction of the mill base viscosity and a good stability. In PVC applications the additive shows a strong decrease of batch and final plastisol viscosity and moreover offers an excellent heat stability.

BYK-1797 – Silicone-containing defoamer for 100 % UV printing inks and OPV. Especially recommended for screen printing inks
Due to their rheological profile, and since they are particularly prone to foaming during application, screen printing inks are especially challenging for defoamers. BYK-1797 offers two advantages. It has strong defoaming properties even at extremely low dosages, but with a little more, leveling can also be greatly improved. Newtonian radiation-curable systems such as UV flexographic inks or substrate printing inks often require additives both to eliminate foam, which may be carried through an enclosed doctor blade and to provide substrate wetting.

DISPERBYK-2023 – Solvent-borne wetting and dispersing additive for liquid printing inks based on TPU, TPA, NC, and vinyl copolymers
Modern solvent-borne printing inks are becoming increasingly polar. That is why it is particularly challenging to find suitable, compatible dispersing additives for NC-based printing inks. At the same time, PU and vinyl systems result in increased polarity as well as a faster printing process. BYK has responded to market demand and developed DISPERBYK-2023. This additive offers optimal dispersion and stabilization of organic pigments, as well as outstanding compatibility across a wide polarity range. DISPERBYK-2023 provides the formulation with virtually Newtonian flow behavior and itself contains a highly volatile solvent. The outstanding properties of DISPERBYK-2023 result in high application speeds with high levels of printing quality, combined with outstanding process reliability.
