Highlight:
ANJEKA-7425A reduces both dynamic and static surface tension
GENERAL DESCRIPTION
Anjeka-7425A is an acetylenic diol-modified siloxane wetting agent designed for aqueous coatings, printing inks, and overprint varnishes. It powerfully reduces surface tension and significantly enhances substrate wetting, effectively preventing crater formation while also delivering excellent defoaming and foam-suppression performance.
PRODUCT DATA SHEET
Chemical Composition: Acetylenic diol-modified siloxane.
Typical Physical & Chemical Properties:
The values provided are typical data for reference and are not to be construed as product specifications.
Property & Condition Typical Value / Range
Appearance Colorless to pale yellow liquid
Density at 23 °C 0.90 - 1.10 g/cm³
Viscosity at 25 °C 10 - 300 mPa·s (cPs)
Active Content 100 %
STORAGE and TRANSPORT
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.
SPECIAL NOTES
Long-term stability in coating systems with pH 4-10. In order to avoid turbidity, a small amount of co-solvent (approx. 5% of the total solvent) is required in the formulation with 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.
APPLICATION GUIDELINES
Industrial Coatings
Features and Benefits:
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.
APPLICATION SECTORS
This additive is recommended for all aqueous coatings, printing inks and overprint varnishes with the addition of a small amount of co-solvent.
RECOMMENDED LEVELS
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.
INCORPORATION and PROCESSING INSTRUCTIOS
This additive can be added at any stage of production, but we recommend adding it at the final stage of coating production.
