ANJEKA7334 Strong reduction of surface tension Solving shrinkage problem for water based system coating

GENERAL DESCRIPTION

Anjeka-7334 is a silicone-based additive designed for use in water-based coatings, printing inks, and overprint varnishes. It enhances leveling and prevents cratering.

PRODUCT DATA

Chemical Composition: Organomodified polysiloxane

Typical Physical Properties:

(The data listed below are typical values and not specifications.)

Property Value

Appearance Colorless to slightly yellow transparent liquid

Solubility Water-based systems

Density (g/cm³ at 23 °C) 0.90–1.10

Viscosity (cps at 25 °C) 300–1500

Active content (%) 100

STORAGE AND TRANSPORT

May exhibit separation or cloudiness if stored below 5 °C. Warm to 20 °C and mix thoroughly before use. Store in a cool, dry place.

Shelf life is not recommended to exceed 12 months.

SPECIAL NOTES

Exhibits long-term stability in coating systems with pH between 4 and 10.

To avoid cloudiness, a small amount of co-solvent (about 5% of total solvent) is recommended in formulations using Anjeka-7334.

APPLICATION GUIDELINES

Industrial Coatings

Key Features and Benefits:

Anjeka-7334 is an organomodified polysiloxane with a very short repeating unit structure. It significantly lowers the surface tension of water-based systems, thereby enhancing leveling and substrate wetting.

Minimal or no foam stabilization

No intercoat adhesion issues

Does not interfere with recoatability

Provides good wetting of silica (e.g. white carbon black)

Excellent compatibility, also effective as an anti-cratering agent

APPLICATION SECTORS

Water-based systems

RECOMMENDED LEVELS

0.1–0.3% additive (as supplied) based on the total formulation weight.

This is a general guideline; optimal dosage should be determined through a series of formulation trials.

INCORPORATION AND PROCESSING INSTRUCTIONS

Can be added at any stage of the production process, including post-addition.
