DOPPEL-LAG-607

Silicone surfactant for aqueous coatings, printing inks and overprint varnishes with strong reduction in surface tension resulting in significantly improved substrate wetting. No increase in surface slip. Solvent-free version of LP-608

Product Data

Composition

Polyether-modified siloxane

Typical Properties

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

Density (20 °C): 1.07g/ml

Active substance: 100 %

Special Note

Solvent-free version of Doppel-LAG-608. The additive requires a small amount of co-solvent in the formulation (approx. 5 % of the total solvent content) in order to avoid turbidity. The effectivity of the silicone surfactant is reduced in systems with higher co-solvent amounts. For these types of formulations we recommend the use of polysiloxanes such as LAG-606


Applications

Coatings and Printing Inks

Special Features and Benefits

The additive provides a large decrease in surface tension in aqueous systems and therefore improves substrate wetting and leveling in particular. Foam stabilization does not occur or only very minimally and recoatability is not affected. The additive does not increase surface slip. If higher surface slip is desired, we recommend combining it with a polysiloxane such as LAG-606

Recommended Use

The additive is recommended for all aqueous coatings, printing inks and overprint varnishes which contain a small proportion of organic co-solvent.
Recommended Levels

0.08-0.5 % additive (as supplied) based upon total formulation.
