EVONIK: Dispersing Additive
A new type of dispersing additive is now available from this company’s Resource Efficiency segment. The additive reportedly has been developed for low-polarity ink systems with a special focus on ceramic inks. Even at high pigment loading, TEGO® Dispers 1010 can deliver low viscosities. The solvent-free, liquid dispersing additive with 100%-active substance content reportedly is easy to handle and dose.
The additive allows for the production of low-viscosity inkjet inks with Newtonian flow characteristics. Small particle sizes, obtained by efficient grinding, result in maximum color intensity, while narrow particle size distribution ensures inks with easy filterability. Sedimentation of all pigment types can be suppressed despite the low viscosity and allows ink systems to achieve long shelf life.
“The product exhibits broad compatibility and can be easily combined with co-additives, such as TEGO Dispers 656, to achieve a desired yield point,” said Anna-Maria Hofmann, Ph.D, director global of marketing for inks and new applications. “Combination with further dispersing additives also permits the compatibility of non-polar solvents, such as hydrocarbons, to be adjusted to that of polar solvents.”
