Application Fields

Due to its chemical structure SILCO GA 2550 is particularly recommended for water based formulations.


SILCO GA 2550 is particularly characterised as highly effective wetting additive for printing inks and overprint varnishes.


Preferred fields of application:

▪ Printing inks and over print varnishes

▪ Water based systems


Recommendation for Use

We generally recommend a dosage of 0.5 – 2.0 % calculated on the total formulation. The optimal dosage has to be determined through preliminary tests.


The additive can be added at any point of the production process at low to medium shear forces.
