Overview of block copolymer dispersant Anjeka 6171

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, significantly reducing the viscosity of the abrasive and effectively improving the color development performance.

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

Acid value: 6-9mgKOH/g

Amine value: 3-6mgKOH/g

Density: 1.06g/L (25℃)

Viscosity: 350-400cps (25℃)

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

The surface treatment of some organic pigments of Hubei Dispersant will have an adverse effect on the effectiveness of the wetting and dispersing agent. In this case, you can try the same type of untreated paint.

Application information

Industrial Coatings

Features and advantages:

Hubei Dispersant This additive makes the pigment deflocculate and maintain stability through steric hindrance. ANJEKA-6171 provides the same charge to the pigment particles. The resulting repulsive force and steric hindrance stabilization can effectively avoid possible co-flocculation, increase the gloss, color strength, transparency and hiding power of the coating, and can also reduce the grinding viscosity.

Auxiliary dosage (purchase form) based on pigment: recommended dosage

Titanium dioxide: 5%—6% 

Inorganic pigments: 10%-15%

Organic pigments: 30%—80%

Carbon black: 30%—120%

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, pre-mix the resin and solvent components of the abrasive, and then slowly add the additives under constant sweeping. Do not add pigments before the additives are evenly mixed.
