What is Polymeric Dispersants
Polymer dispersants are composed of macromolecular compounds and act as surfactants with both lipophilic and hydrophilic properties.
They can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids, thereby forming a stable system.

Core Benefits of Celotech Ruico Polymeric Dispersants
Even in environments such as long-term storage, temperature changes, shear stress or electrolyte interference, polymeric dispersants can effectively prevent particles in the system from approaching and agglomerating again, thereby significantly reducing problems such as coarsening, settling, floating and blooming, and achieving long-term stability.
Compared with traditional small molecule dispersants, polymeric dispersants use steric hindrance and multi-point adsorption principles to achieve a more stable and lasting dispersion effect at a lower addition amount. This reduces the hidden costs of rework, filter blockage or storage failure.
Celotech Ruico Polymeric Dispersants Properties
It can improve the performance of various products such as coatings, fillers, and water-based inks. The specific realization is to enhance color intensity, product covering power, gloss and final application uniformity.
Polymeric dispersants can make the grinding media move more smoothly, improve shearing and grinding transfer efficiency, and increase the effective crushing ratio per unit time, thus reducing grinding energy consumption.
In water-based coatings, the high surface tension of water will cause wetting difficulties, and polymeric dispersants can effectively help the raw materials to be effectively and quickly wetted by the aqueous medium.
Whether it is organic pigments or carbon black, polymeric dispersants can achieve excellent dispersion performance. These properties are crucial for the manufacture of high-quality water-based coatings, inks, etc.
The special properties of polymeric dispersants can inhibit active sites on the surface of shielding particles and reduce non-specific adsorption between pigment-pigment and pigment-resin.
The good dispersion state under the polymeric dispersants can reduce the viscosity of the product and make the viscosity more controllable, thereby improving the rheology and workability and pumpability of the product.
Application of Polymeric Dispersants
The main function of polymeric dispersants in coatings and paints is to improve the storage stability and application performance of the coatings, and to enhance the color intensity, gloss, and opacity of the film.
In ink applications, they are mainly used to disperse pigments and fillers, allowing them to be evenly dispersed in the solvent or resin system, resulting in more stable ink performance and better printing quality.
In color pastes, polymeric dispersants enable high solids content and low viscosity, prevent agglomeration and color separation, and can halve the grinding time. Â The color remains fine and vibrant even after long-term storage.
In adhesives, the application of polymeric dispersants is mainly to prevent powder agglomeration and sedimentation. They allow the colloid to maintain low viscosity and high fluidity, and enable more uniform and dense application.

Quick FAQ for Polymeric Dispersants:
You can choose high-performance polymeric dispersants compatible with various product systems, and use appropriate shearing and grinding equipment and processes in the factory.
They differ in molecular structure, dispersion principle, and stability. If you want to choose a lower-cost dispersant with less demanding requirements, you can choose a small molecule dispersant.
The quality is highly related to the manufacturer’s synthesis process and formula compatibility. In practical applications, it is best to choose the most suitable manufacturer through small-scale experiments.
Polymer dispersants combine the advantages of many similar products. If you pursue long-term stable and high-quality products, polymer dispersants are still the best choice.
