Anjeka 7425A water-based substrate wetting additive 100% active content Alkyne alcohol and polyether siloxane grafted compound reduces surface tension improves wettability TEGO 4100

ANJEKA-7425A

GENERAL DESCRIPTION

Anjeka-7425A is an alkynyl glycol modified siloxane wetting agent for aqueous coatings, printing inks and overprint varnish, which can strongly reduce surface tension and significantly improve the wetting properties of the substrate, and effectively prevent shrinkage with excellent defoaming and foam inhibition effects.

PRODUCT DATA

Chemical composition: alkydiol modified siloxane.

Typical physical and chemical data:

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

Appearance Colorless to light yellow liquid

Density g/cm³ (23℃) 0.90-1.10

Viscosity cps (25℃) 10-300

Active ingredient (%) 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.
