APPLICATION GUIDELINES
Water-based inks, coatings, water-based general-purpose color pastes.
Properties and advantages.
This additive causes pigment deflocculation through spatial stabilization. Due to the small particle size of the deflocculated pigment, it is possible to obtain a high gloss, as well as an increase in color strength. In addition, the transparency of transparent pigments and the hiding power of opaque pigments are improved. Due to the reduced viscosity, the flow properties are improved and the pigment content can be increased.
This additive is particularly suitable for the production of stable, resin-free pigment concentrates with pigment contents of 30-70%. These pigment concentrates can be used for paint mixing with standard aqueous bases.
GUIDELINES

●--Special recommendation; ○--Recommendation
This additive is also recommended for the production of stabilized resin-free pigment concentrates for the preparation of waterborne coatings with no floating/blooming colors.
RECOMMENDED LEVELS
Additive dosage (in purchased form) is based on pigment:
Inorganic pigments
2% - 10%
The above data are empirical and the optimum dosage should be determined through a series of tests.
INCORPORATION AND PROCESSING INSTRUCTIOS
It can be added before grinding, and has good general effect in water-soluble, aqueous dispersion and emulsion system.
