Matte viscosity-reducing dispersant: an invisible promoter of scientifically empowering material performance

Matte viscosity-reducing dispersant: an invisible promoter of scientifically empowering material performance

In the field of material science and surface treatment, the matte effect has become an important development direction 

in the coating, ink, plastic and cosmetic industries due to its unique visual texture and functional requirements. One of 

the key technologies to achieve this effect is the application of matte viscosity-reducing dispersants. This type of special 

additive precisely controls the microstructure inside the material, while reducing the viscosity of the system, ensuring 

the uniform dispersion and stable existence of the matte components, thereby giving the material low gloss and high 

uniformity surface characteristics. Its advantages can be analyzed from two dimensions: scientific principles and 

practical applications.


1. Synergistic effect of viscosity reduction and dispersion

In the process of material processing, excessive viscosity often leads to construction difficulties, increased energy 

consumption, and even affects the uniformity of the final product. Matte viscosity-reducing dispersants can form a 

dynamic balance in the system through their unique molecular structure design: on the one hand, the hydrophilic 

groups and hydrophobic groups in their molecular chains interact with the medium and solid particles respectively, 

reducing the liquid-solid interfacial tension, so that the originally agglomerated particles are fully wetted and dispersed; 

on the other hand, polymer dispersants can form an adsorption layer on the surface of the particles, preventing the 

particles from reaggregating through steric hindrance or electrostatic repulsion, thereby significantly reducing the 

viscosity of the system. This viscosity reduction effect is not a simple dilution, but a rheological improvement achieved 

by optimizing the particle distribution, which not only ensures processing fluidity, but also avoids sedimentation 

problems caused by too low viscosity.


2. Precise control of matte effect

The core of the matte effect lies in controlling the light scattering properties of the material surface. Traditional methods 

usually achieve this by adding matte powder (such as silica), but the dispersion uniformity of the matte powder directly 

affects the final effect. Matte viscosity-reducing dispersants can be directional adsorbed on the surface of the matte 

powder, and by adjusting the interaction force between particles, it can present a uniform directional arrangement in 

the system. This arrangement not only enhances the stability of the matting powder, but also avoids uneven gloss 

caused by local over-density or over-sparseness. In addition, the dispersant can maintain low viscosity when the 

matting powder content is high, ensuring a balance between construction performance and matte effect. For 

example, in UV light-curing coatings, some dispersants can stably disperse the matting powder in a solvent-free 

system, and maintain low viscosity and long-lasting matting performance even at high filling levels.


3. The dual advantages of environmental protection and compatibility

With increasingly stringent environmental regulations, water-based systems and low VOC (volatile organic compound) 

materials have become industry trends. Matte viscosity-reducing dispersants are designed with full consideration of 

environmental protection needs. Their molecular structure usually does not contain heavy metals or harmful solvents 

and can be widely used in water-based coatings, inks and cosmetics. At the same time, this type of dispersant has 

good compatibility with a variety of resin systems (such as acrylic, polyurethane, epoxy resin, etc.) and can adapt to 

different formulation requirements. For example, some products are not only suitable for traditional solvent-based 

systems, but can also be used in water-based systems without resin grinding, which significantly broadens their 

application scenarios.


4. Guarantee of long-term stability

During the storage and use of materials, particle sedimentation, stratification or flocculation are common problems. 

Matte viscosity-reducing dispersants can effectively inhibit particle movement and prevent sedimentation and hardening 

by forming a stable adsorption layer and steric hindrance effect. Experiments show that matte slurries using specific 

dispersants can still maintain uniform dispersion under high-temperature storage conditions, without rust cans or 

powdering. This stability not only extends the shelf life of the product, but also reduces waste in the production 

process, which is in line with the concept of sustainable development.


5. Multifunctionality across fields

The application of matte viscosity-reducing dispersants is far more than coatings and inks. In plastic processing, it can 

improve the dispersibility of fillers (such as calcium carbonate and talcum powder) and enhance the mechanical properties 

and surface texture of materials; in the field of cosmetics, it can evenly disperse matte powders, giving lipsticks, foundations 

and other products a soft matte effect while maintaining a delicate and comfortable touch. This cross-domain adaptability 

stems from its universal design based on physical and chemical principles, making it an indispensable "invisible assistant" 

in materials science.


Conclusion

Matt viscosity-reducing dispersants provide precise solutions for modern materials science through the synergistic effects 

of viscosity reduction, dispersion, stabilization and environmental protection. Its scientific principles are not only reflected 

in the interaction design at the molecular level, but also verified through practical applications that it has comprehensive 

advantages in improving product performance, optimizing processing technology and meeting environmental protection 

needs. With the continuous advancement of technology, this type of dispersant is expected to play a key role in more 

emerging fields (such as 3D printing materials, flexible electronics, etc.), and promote the development of material 

surface treatment technology towards higher performance and more sustainable directions.
