Modified Siloxane Wetting Agent For Water-based Printing Ink Surface Tension Reduction Foam Suppression

Anjeka-7425 is a modified siloxane wetting agent for aqueous coatings, printing inks and overprint varnish, which can strongly reduce surface tension and significantly improve substrate wetting performance, effectively preventing shrinkage and excellent defoaming and foam inhibition effects.

The data given in this data sheet are typical values, not technical specifications of the product.

Layering or turbidity may occur at temperatures below 5 °C. Heat to 20 °C and mix thoroughly.

Storage is not recommended for more than 12 months.

Long-term stability in coating systems with a pH of 4-10. To avoid turbidity, a small amount of co-solvent (approx. 5% of the total solvent) is required in the formulation of Anjeka-7425. In systems with a high co-solvent content, the effectiveness of the silicone surfactant is reduced and we recommend Anjeka-7333 for this type of formulation.

The additive effectively reduces static surface tension and dynamic surface tension, is highly compatible and easy to mix, improves substrate wetting properties and has excellent anti-foaming and defoaming properties. The additive does not increase the surface slip. If higher surface slip is required, it is recommended to add Anjeka-7333.

This additive is recommended for all aqueous coatings, printing inks and overprint varnishes with the addition of a small amount of co-solvent.

0.05-0.5% of additives (in purchased form) based on total formulation.

The above figures are empirical and the optimum amount should be determined through a series of tests.

This additive can be added at any stage of production, but we recommend adding it at the final stage of coating production.
