An overview of polymer polyamide dispersant Anjeka 6162

Anjeka6162 is a polymer polyurethane type high-efficiency carbon black dispersant, which has excellent dispersing properties for various high-pigment carbon blacks such as FW200.

product information

Chemical composition: high molecular weight block copolymer solution containing pigment affinity groups.

Typical physical and chemical data: The data given on this data page are only typical values, not technical indicators of the product.

Amine value: 3 mg KOH/g

Density (20 °C): 1.05 g/ml

Non-volatile matter (20 minutes, 150 °C): 80%

Solvent: N,N dimethylpyrrolidone

Storage and transportation

When the temperature is lower than 15 °C, delamination or turbidity may occur. Heat to 20 °C and mix thoroughly.

Special attention to polymer dispersants

The surface treatment of some organic pigments of Hubei polymer dispersant will adversely affect the effectiveness of the wetting and dispersing agent. In this case, try untreated pigments of the same type. This product is more suitable for medium-to-high polarity systems, and the dispersion stability performance should be tested for low- and medium-polarity systems.

Application information

Paint industry

Features and advantages:

The high molecular weight additives deflocculate and stabilize the pigments through steric hindrance. Anjeka6162 provides the same charge to the pigment particles. The resulting repulsive force and steric stabilization can effectively avoid possible co-flocculation, so that the multi-pigment system will not produce floating and blooming. The deflocculation performance of the additive can increase the gloss, color strength, transparency and hiding power of the coating, while reducing the viscosity of the abrasive.

Recommended dosage

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

Inorganic pigments: 5%-15%

Organic pigments: 10%—90%

Carbon black: 50%—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 grinding material first, and then the pigments.
