Understand matte powder dispersant in one article: "homogeneous magic" in coatings,
inks and cosmetics
Mat powder dispersant is a chemical additive specially used to improve the dispersibility of matte powder
(such as silica, matting powder, etc.) in the medium. It is widely used and has significant technical characteristics.
1. Core application areas
Coating industry
Wood and furniture coatings: used in the preparation of matte paint, by directional arrangement of matte powder
particles, a uniform matte surface is formed, while improving the scratch resistance and feel of the coating.
Industrial coatings:
in anti-corrosion coatings and coil coatings, ensure the stable dispersion of matte powder, enhance the hiding power,
weather resistance and anti-settling performance of the coating.
Leather coatings: while achieving a matte effect, maintain the softness and breathability of the leather and improve
the texture of the product.
Plastic processing
As a filler dispersant, it improves the dispersibility of inorganic fillers (such as talcum powder and calcium carbonate) in
the plastic matrix, and improves the mechanical properties, surface finish and processing fluidity of plastic products.
Ink and Printing
In UV ink and offset ink, matte powder is prevented from settling, ensuring uniform color of printed products, avoiding
floating color and flowery phenomenon, and improving printing quality.
Cosmetics
Used in makeup products such as foundation and loose powder, matte powder (such as mica and silica) is evenly dispersed,
providing delicate skin feel and lasting matte makeup effect, while enhancing product stability and usage experience.
2. Mechanism of Action and Technical Advantages
Efficient Dispersion and Directional Arrangement
The matte powder dispersant molecules contain functional groups with strong affinity to the matte powder surface, which
wrap the particles through chemical adsorption, reduce interfacial tension and prevent agglomeration.
In coatings or inks, the matte powder is arranged in a directional manner to form a uniform matte effect, while improving
the transparency or hiding power of the system (depending on the type of pigment).
Anti-sedimentation and Rheology Control
Through steric hindrance or electrostatic repulsion mechanism, matte powder particles are prevented from settling during
storage, extending the shelf life of the product.
Reduce system viscosity, improve construction performance (such as leveling and anti-sagging), and improve production
efficiency.
Environmental protection and compatibility
Water-based matte powder dispersants meet the requirements of low VOC emissions and are suitable for environmentally
friendly resin systems such as water-based acrylic and polyurethane.
It has good compatibility with a variety of resins and pigments, is suitable for resin-free grinding processes, and simplifies the
production process.
3. Market trends and development prospects
Demand growth
As environmental regulations become stricter, the demand for environmentally friendly products such as water-based coatings
and UV coatings has increased, driving the growth of the matte powder dispersant market.
Consumers' requirements for product performance (such as matte effects and weather resistance) have increased, driving the
demand for high-performance dispersants.
Technology upgrade
Environmentally friendly dispersants (such as bio-based and solvent-free) have become the focus of research and development
to cope with VOC restrictions and sustainable development requirements.
Through technologies such as controlled free radical polymerization, the molecular structure of dispersants is optimized to
improve dispersion efficiency and stability.
Application expansion
From traditional coatings to emerging fields such as 3D printing materials and electronic packaging materials, the market
boundaries are expanded.
In functional coatings (such as self-cleaning and anti-fogging), matte powder dispersants are combined with nanotechnology
to develop high-performance products.
Conclusion
Through its unique chemical structure and mechanism of action, matte powder dispersants play a key role in coatings,
plastics, inks, cosmetics and other fields, especially in improving matte effects, preventing sedimentation and improving
rheological properties. With the promotion of environmental protection regulations and technological upgrades, the
market demand for matte powder dispersants will continue to grow and develop in the direction of high performance
and environmental protection, providing innovative solutions for related industries.
