Typical materialized data

The data given on this data sheet are only typical values, not the technical specifications of the product.

 

Density (20 °C)

1.05 g/ml

 

 storage and transportation

At temperatures below 20°C, the product may freeze. Heat to at least 30°C and stir before use.

 

  Application field  

  Room temperature curing system   

Features and Benefits: The additive deflocculates pigments through steric stabilization. Due to the small particle size of the deflocculated pigments, color strength can be enhanced. In addition, due to the reduction in viscosity, the amount of pigment added can be increased. The additive prevents floating and blooming in complex pigment/paste combinations as well as in rather difficult colors.

 
  Recommended use

Especially recommended for the production of colorants used in gel coats; also recommended for pigment stabilization in gel coats.

  Recommended dosage

Auxiliary dosage (as purchased) is based on:

Titanium dioxide	2-5 %
Organic Pigments	10-15 %
Carbon black	10-20 %

 

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

For optimum performance, the additive must be added slowly to the resin with agitation. Pigments and fillers can only be added after the additives have been completely dispersed. Dispersion can then proceed, and after the dispersion is complete, more resin can be added if necessary.
  paint industry

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 reduced viscosity, flow properties are improved and pigment loading can be increased.

Recommended use	Specially Recommended
utomotive coatings	Specially Recommended
Can Paint	Specially Recommended
Leather Coatings	Specially Recommended

 

This additive has been specially developed for the production of stable aqueous effect pigment dispersions (with or without dispersing resin).

  Recommended dosage

Auxiliary dosage (as purchased) is based on:

Inorganic Pigment	5-10 %
Titanium dioxide	4-7 %
Organic Pigments	15-30 %
Carbon black	30-50 %
Effect pigments	3-5 %

 

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  

For optimum performance, the additive must be added slowly (with agitation) to the grinding resin/cosolvent mixture or to a shear stable aqueous dispersion. In resin-free systems, it is only necessary to mix the additive with water uniformly. Pigments can only be added after the additives have been completely dispersed.

 

 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 achieved, as well as enhanced color strength. In addition, transparency is also improved, and flow properties are improved due to the reduction in viscosity, and the addition of pigments can be increased.
  Recommended use  

Especially recommended for gravure, flexo and screen printing inks. The additive is particularly suitable for the production of stable resin-free pigment concentrates with a pigment content of 30-60%. These pigment concentrates can be used for letdown to standard waterborne binders such as acrylic dispersions or water soluble acrylic resins.
 Recommended dosage

Auxiliary dosage (as purchased) is based on:

 

Titanium dioxide	2-5 %
Organic Pigments	10-15 %
carbon black	10-20 %

 

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 should be done in water or in the presence of grinding resin. Pigments can only be added after the additives have been completely dispersed.
  Thermoplastics  

 Recommended use

Additives are recommended for the production of fatty acid ester-based liquid masterbatches for colored thermoplastics (especially PET).

  Recommended dosage

Auxiliary dosage (as purchased) is based on:

Inorganic Pigment	5-10 %
Titanium dioxide	4-7 %
Organic Pigments	15-30 %
Carbon black	30-50 %
Effect pigments	3-5 %

 

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 

For optimum performance, the additive must be added slowly to the carrier system with agitation. Pigments can only be added after the additives have been completely dispersed.
