Product Description
German technical background VOK®-SL 348 leveling agent
VOK®-SL 348 silicone surfactant for waterborne coatings, printing inks and overprint varnishes to significantly reduce surface tension and improve substrate wettability. Does not increase surface slip. Suitable for co-solvent-free systems.
Product information
Chemical composition
Polyether-modified organosiloxanes
Typical physicochemical data
The data presented on this data page is typical and not a product specification.
Effective Serving Size: 100%
Density (20 °C): 1.06 g/ml
Storage and transportation
Storage or transport below 5 °C may be stratified or cloudy. Heat to 20 °C and stir well.
Special considerations
The additive is also suitable for systems that do not contain organic co-solvents. If the co-solvent content in the system is increasing, the silicone surfactant will gradually lose its effect. In such formulations, we recommend the use of polysiloxane additives, e.g. VOK®-SL 333.
Application areas
Coatings and printing inks
Product features and benefits
The additive significantly reduces the surface tension of aqueous systems and therefore significantly improves the wetting and leveling of the substrate. May cause slight foam stabilization, but does not affect recoatability. The additive does not increase surface slip. For better surface slip, it is recommended to use polysiloxane additives such as VOK®-SL 333.
Recommended Use
The additive is recommended for all water-based coatings, printing inks and overprint varnishes, especially for co-solvent-free formulations.
Recommended dosage
0.05-0.5% additive dosage (form of supply) is based on total formulation.
The above recommended dosage is for reference only, and the appropriate dosage needs to be determined after a series of tests.
Addition method and processing guidance
This additive can be added at any stage of production, but we recommend adding it later.
Adhesive
Product features and benefits
The additive significantly reduces the surface tension of water-based adhesives and thus improves the wettability of the substrate. There may be a slight foam stabilizing effect.
The auxiliary
Does not increase surface slip. They are particularly suitable for co-solvent-free adhesive systems.
Recommended dosage
0.05-0.5% additive dosage (form of supply) is based on total formulation.
The above recommended dosage is for reference only, and the appropriate dosage needs to be determined after a series of tests.
Addition method and processing guidance
This additive can be added at any stage of production, but we recommend adding it later.
