Anjeka 7423 water-based substrate wetting agent polyether-modified siloxane for all aqueous coatings, printing inks

DESCRIPTION

Anjeka-7423 is a silicone surfactant for aqueous coatings, printing inks and overprint varnishes that strongly reduces surface tension and significantly improves substrate wetting ability. Compared to Anjeka-7422, Anjeka-7423 provides more stable usability in the pH range of 3-12.

PRODUCT DATA

Chemical composition: Polyether-modified silicone.

Typical Physical and Chemical Data:

The data given on this data sheet are typical values and are not product specifications.

Appearance Colorless transparent liquid

Active ingredient (%): 100

Density g/cm³(23℃): 0.98-1.04

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 of Anjeka-7423. 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:

This additive enhances leveling and substrate wetting by strongly reducing the surface tension of aqueous systems. It has no or slight foam stabilizing effect, does not reduce recoatability, and has good wettability for white carbon black. The additive does not increase surface slip. For higher surface slip 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.
