Versator solid/]Liquid blender can mix, blend and defoam two or more components.
In contrast, low viscosity inks are easier to defoam but more susceptible to defect formation; therefore, they require weaker but more compatible defoamers.
Thus, it is also harder to defoam these formulations and microfoam problems (trapped air bubbles) are more acute.
To effectively reduce dynamic surface tension and provide a wide compounding latitude for formulators looking for a high-performance surfactant that can both defoam and act as a wetting agent, EnviroGem ADO1 surfactant is the solution.
Lower viscosity systems are generally easier to defoam as the air bubbles can rise more easily and the coating has greater flow.
Evonik has found ways to overcome certain physical and chemical limiting factors and now offers multifunctional additives that both wet and defoam at the same time or are energy curable additives that provide both slip and flow properties.
