Overview of polymer dispersant Anjeka 6161

Wetting and dispersing additive for solvent-based automotive coatings, industrial coatings and pigment concentrates. It is especially suitable for stabilizing ultra-fine carbon black and organic pigments, especially two-component polyurethane and baking systems. Significantly reduce the viscosity of the abrasive.

Storage and transportation

When the temperature is lower than 0°C, stratification or muddy oil may occur. Heat to 20°C and mix thoroughly.

pay attention

Polymer dispersant The surface treatment of some organic pigments will adversely affect the effectiveness of the wetting and dispersing agent. In this case, the same type of untreated pigment can be tried. When used in coil coatings, the interaction between the cationic additive and the acid catalyst must be considered. Free acids or epoxy-blocked acids are more suitable than amine-blocked acids.

Application information

Industrial Coatings

Features and advantages:

The additive de-flocculates and maintains stability of the pigment through steric hindrance. ANJEKA-6161 provides the same charge to the pigment particles. The resulting repulsive force and steric hindrance stabilization can effectively avoid possible co-flocculation, so that the multi-pigment system will not produce floating color and blooming. As a result, the gloss, color strength, transparency and hiding power of the coating can be increased, and the grinding viscosity can be reduced at the same time.

Recommended dosage

The amount of additives (purchased form) based on the pigment:

Titanium dioxide: 5%—6% 

Inorganic pigments: 10%-15%

Organic pigments: 30%—80%

Carbon black: 20%—140%

The above data are empirical dosages, and the optimal dosage of a needs to be determined through a series of experiments.

Joining method and processing guidance

In order to obtain a good performance, the additives should be added to the abrasive first, and then the pigments. First premix the resin and solvent components of the abrasive, and then slowly add the additives under constant stirring. Do not add pigments before the additives are evenly mixed.
