  storage and transportation  

When stored or transported at temperatures below 0°C, stratification or turbidity may occur. Heat to 20°C and stir before use.

  Application field

  Printing ink     

Features and Benefits: The additive deflocculates pigments through steric stabilization. Due to the small particle size of the deflocculated pigments, high gloss can be obtained, as well as improved color
color intensity. In addition, the transparency of transparent pigments and the hiding power of opaque pigments are also improved. Improved flow properties due to reduced viscosity, and
Can increase the pigment content.

  Recommended use  

The additive is particularly suitable for producing stable resin-free pigmented miniatures with a pigment content of 30-60%. These pigment concentrates can be used in standard aqueous binders
Letdowns such as acrylic dispersions or water-soluble acrylics.

  Recommended dosage     

Auxiliary dosage (purchased form) based on:

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

 Joining method and processing guidance    

Grinding can only be carried out in water (free of resins, amines and co-solvents). Mix the adjuvant with water, and then add the pigment after the adjuvant is fully dispersed.

Features and Benefits: The additive deflocculates pigments through steric stabilization. Due to the small particle size of the deflocculated pigments, high gloss can be achieved, as well as enhanced color strength. In addition, the transparency of transparent pigments and the hiding power of opaque pigments are also improved. Due to the reduction in viscosity, flow properties are improved and pigment levels can be increased.

  Recommended use  

This additive is recommended for the production of stable resin-free pigment concentrates for the preparation of waterborne paints without floating/floating.

  Recommended dosage

Auxiliary dosage (as purchased) is based on:

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

Grinding can only be carried out in water (free of resins, amines and co-solvents). Mix the adjuvant with water, and then add the pigment after the adjuvant is fully dispersed.

  Adhesive

Features and advantages: The additive can improve the dispersion quality of pigments and fillers, and it can deflocculate pigments and fillers through steric stabilization. Due to the reduced viscosity, flow properties are improved and pigment loading can be increased.

  Recommended use

This additive is especially recommended for dispersing pigments and fillers in resin-free water.
