Silicone Leveling Agent For Wood Coatings And Furniture Finishes Improves Levelling And Gloss TEGO 410

Anjeka 7331 is a silicone leveling additive with medium reduction of surface tension.

polyether-modified polydimethylsiloxane.

The values given in this data sheet describe the typical properties and do not constitute specification limits.

Separation and turbidity may occur at temperatures below 5℃. Warming to 20℃ and mix well before use.

Before massive use, user should determine by a series of test whether foam is stable in certain systems and check the recoatability and crater development.

The additive reduces the surface tension of the system to a medium level. It increases slip and improves levelling and gloss. Silicone additives prevent the formation of Benard cells. At the same time, Anjeka 7331 improves the wettability of the substrate and produces anti-stickiness.

Anjeka7331 is suitable for all solvent-borne, solvent-free and water borne coatings. In the two-component polyurethane system, the additive can also be mixed into the isoacid ester curing agent.

Suitable for water-borne coating, solvent-borne and solvent-free coating.

Recommend application: solvent-borne and solvent-free coating.

As supplied calculatedon total formulation: 0.025-0.2%.

The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.

The additive can be incorporated during any stage of the production process, including post-addition. Thinning before incorporation may make dosing easier.

Benefits to our customers and collaboration partners:

• stable large-scale production, better quality control
• lower production unit cost

Collaboration Opportunities:

• contract manufacturing and OEM/ODM collaboration opportunities

Q: What does “medium” surface tension reduction mean compared to high or low alternatives?

“Medium” is Anjeka 7331’s competitive advantage. High reduction can over-wet and destabilize some systems. Low reduction may not adequately wet difficult substrates. Anjeka 7331 sits in the optimal range — effective wetting without disrupting your formulation balance.

Q: Can it be used in water-based systems?

Yes. Anjeka 7331 is compatible with both water-borne and solvent-borne systems. This versatility makes it an efficient single-product choice for manufacturers running multiple coating lines.

Q: Will it affect recoatability?

Anjeka 7331 can influence surface energy, which may affect intercoat adhesion in some recoating scenarios. Always test recoatability in your specific system before mass production. If recoatability is a critical parameter, conduct localized testing or reduce dosage.

Q: The product became turbid after cold storage. Is it still usable?

Yes. Below 5 degrees C, separation or turbidity may occur. This is normal for silicone polyether products. Simply warm to 20 degrees C and stir thoroughly. Performance is fully restored with no degradation.

Q: How does it prevent Benard cells?

Benard cells form due to surface tension differences during solvent evaporation, causing swirling flow patterns in the drying film. Anjeka 7331’s silicone component suppresses the Marangoni effect, preventing these defects from forming as the film dries.

Q: Can it be used in two-component polyurethane systems?

Yes. Anjeka 7331 has a unique advantage in 2K PU systems — it can be pre-mixed into the iso/acid ester curing agent rather than the base, giving more uniform distribution throughout the final coating. Always verify compatibility with your specific hardener system.

Q: What packaging options are available?

• 25 kg iron drum
• 180 kg plastic drum
• Custom packaging available for large volume OEM orders

Q: Do you offer free samples?

Yes. Free samples are available for qualified new customers. Contact us with your formulation details and we will recommend the optimal starting dosage for your specific system.
