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.
