Application Fields
Due to its chemical structure SILCO GA 1111 is particularly recommended as wetting and dispersing additive for organic pigments and carbon black.
 
Preferred fields of application:
▪ Printing inks
▪ Water based systems
 
Recommendation for Use
We recommend a dosage of 1 - 10 % calculated on the total pigment weight.
 
The optimal dosage has to be determined through preliminary tests. The dosage depends on the pigment’s chemical nature, the shape and the particle surface.
 
The additive should be added to the mill base before predispersion.
