German technical background VOK®- SL 3450 organosilicon surfactant

It is suitable for water-based printing ink and finish varnish, ink-jet ink, water-based paint, adhesive and curing products to reduce surface tension. It is especially suitable for improving the wetting of water-based system on non-porous substrates. Does not increase the smoothness of the surface.

Chemical composition

Polyether modified siloxane

Typical physical and chemical data

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

Active substance: 99.99%

Density (20 ℃): 1.03 g/ml

Application field

Printing ink

Product features and advantages

The additive can reduce the surface tension of water-based system. VOK®- SL 3450 especially improves the wetting and leveling of non-polar substrates, such as polyethylene, polyvinyl chloride, polyethylene terephthalate and coated offset paper. Its foam stabilizing tendency is very low and does not affect the recoating property. VOK®- SL 3450 has good substrate wettability, especially suitable for thin coating applications. The additive does not increase the smoothness of the surface. For higher surface smoothness, it is recommended to use polysiloxane additives such as VOK®- SL 333 or VOK®- SL 3760。

Recommended use

This additive is recommended for all kinds of water-based printing inks and varnishes, especially for formulations without cosolvent.

Printing ink

Finish varnish

Recommended dosage

0.1-1% additive dosage (supply form) is based on the total formula, in printing ink and varnish.

The above recommended dosage is for reference, and a good dosage needs to be determined through a series of tests.

Addition method and processing guidance

It can be added at any stage of the production process, but it is better to add it at the last stage.
