BYK 347 Silicone Surfactant

BYK -347

Silicone surfactants for water-based coatings, printing inks and overprint varnishes , Significantly reduces surface tension and improves substrate wetting. Does not increase surface slip. Suitable for systems without co-solvents. Particularly good recoatability for thin coats (automotive coatings).

Chemistry Composition

polyether modified silicone

Typical Materialized data

The data given on this data page are only typical values, not the technical indicators of the product.

special Note

This additive is also suitable for systems without organic co-solvents. If the co-solvent content in the system continues to increase, the silicone surfactant will gradually lose its effect. In such formulations we recommend the use of polysiloxane additives such as BYK-333.

Apply Domain

paint and printing inks

Product characteristics and advantages: This additive can significantly reduce the surface tension of the water-based system, so Greatly improves substrate wetting and leveling. May cause slight foam stabilization but will not affect recoatability. BYK-347 has very good substrate wetting properties, especially for thin coatings. This additive does not increase surface slip. For better surface slip, combination with polysiloxane additives such as BYK-333 is recommended.

Recommended Purpose

This additive is recommended for all water-based paints, printing inks and varnishes , especially for formulations without co-solvents.

Suggestions Dosage

0.05-0.5% additive level (supplied form) based on total coating formulation.

0.1-1% additive dosage (purchase form) based on the total formulation of printing ink .

The above recommended dosage is for reference only, the optimal dosage needs to go through a series of experiments Sure.

Adding method and processing guidance

This additive can be added at any stage of production, but we recommend adding it later.
