Application of metallic pigment dispersants
Metallic pigment dispersants are widely used in many industries such as coatings, inks, plastics, and cosmetics.
Their core function is to improve the dispersibility, stability, and glossiness of metallic pigments in the system.
The following is a detailed introduction:
1. Coatings industry
Automotive coatings
Application scenarios: Automotive coatings have extremely high requirements for gloss, weather resistance,
and decorativeness. Metallic pigments such as aluminum powder and copper powder are often used to make
metallic glitter paints.
Function: Metallic pigment dispersants can effectively prevent metallic pigments from agglomerating in the
coating, making them evenly dispersed, and improving the glossiness and glittering effect of the paint film.
At the same time, they can also enhance the water resistance, salt spray resistance, and other properties of the
paint film, and extend the service life of the car paint.
For example: When producing silver automotive coatings, adding an appropriate amount of metallic pigment
dispersants can make aluminum powder evenly distributed in the resin matrix to form a smooth and shiny paint
film, which improves the appearance texture of the car.
Industrial coatings
Application scenarios: Industrial coatings are used in construction, machinery and equipment, ships, and other
fields, and have certain requirements for the corrosion resistance, wear resistance, and decorativeness of the
coatings.
Function: Metallic pigment dispersants can improve the dispersion stability of metallic pigments in industrial
coatings, so that the coatings have good hiding power and decorative effects. At the same time, they can also
enhance the adhesion and chemical corrosion resistance of the coatings, and protect the substrate from erosion
by the external environment.
Example: Adding metallic pigment dispersants to ship coatings can make the metallic pigments evenly dispersed in the
coatings, forming a dense protective film, which effectively prevents corrosion of the hull by seawater, salt spray, etc.
2. Ink industry
Printing inks
Application scenarios:
In offset printing, gravure printing, flexographic printing and other printing processes, metallic pigment inks are often
used to make high-end packaging, labels, greeting cards and other products to enhance the visual effects and
attractiveness of the products.
Function: Metallic pigment dispersants can improve the dispersion and fluidity of metallic pigments in inks, so that the inks
can be evenly transferred to the substrates during the printing process, forming clear and bright metallic luster patterns.
At the same time, it can also improve the drying speed and adhesion of the inks to ensure the quality of printed products.
For example: When making high-end cosmetic packaging boxes, using ink containing metal pigment dispersants for
printing can make the surface of the packaging box present a gorgeous metallic luster, enhancing the grade and brand
image of the product.
Inkjet ink
Application scenario:
Inkjet ink is widely used in advertising production, indoor and outdoor decoration and other fields, and has high
requirements for the color vividness, weather resistance and inkjet performance of the ink.
Function:
Metallic pigment dispersants can make the metallic pigments disperse evenly in the inkjet ink, ensuring that the printed
patterns are bright in color and high in gloss. At the same time, it can also improve the UV resistance and water resistance
of the ink, so that the inkjet works can maintain bright colors and good visual effects for a long time in outdoor environments.
Example: In outdoor advertising inkjet printing, the advertising pictures printed with ink containing metal pigment
dispersants can still maintain clear patterns and bright metallic luster even under sunlight and rain.
3. Plastic industry
Injection molding products
Application scenario:
When producing injection molding products such as automotive interiors, home appliance housings, toys, etc., metallic
pigments are often added to give the products a unique metallic texture and appearance.
Function: Metallic pigment dispersants can promote the uniform dispersion of metallic pigments in the plastic melt, prevent
pigment agglomeration and precipitation, and make the surface of injection molded products present a uniform and bright
metallic luster. At the same time, it can also improve the mechanical properties and processing properties of plastic products.
Example: When producing automobile dashboards, adding metallic pigment dispersants can make aluminum powder evenly
dispersed in the plastic matrix, so that the surface of the dashboard has a metallic texture and improve the grade of the car interior.
Extruded products
Application scenarios:
Extrusion technology is often used to produce plastic pipes, profiles, films and other products. Adding metallic pigments to
extruded products can increase the decorativeness and aesthetics of the products.
Function: Metallic pigment dispersants can ensure that metallic pigments are stably dispersed during the extrusion process to
avoid color differences and surface defects. At the same time, it can also improve the surface smoothness and glossiness of
extruded products and improve the appearance quality of products.
Example: When producing decorative plastic profiles, the use of metallic pigment dispersants can make metallic pigments
evenly distributed on the surface of the profiles to form a beautiful metallic texture effect.
4. Cosmetics Industry
Cosmetics Products
Application Scenarios:
In cosmetics such as eye shadow, lipstick, and nail polish, adding metallic pigments can give the products a shiny and
gorgeous appearance, satisfying consumers' pursuit of fashion and personality.
Function: Metallic pigment dispersants can evenly disperse metallic pigments in the cosmetic matrix, improving the gloss
and color saturation of the product. At the same time, it can also ensure that the texture of the cosmetics is delicate and
evenly applied, and enhance the product's usage experience.
For example: When making golden eye shadow, adding metallic pigment dispersants can evenly distribute the gold
powder in the eye shadow powder, so that the eye shadow will present a bright golden luster after coloring, enhancing
the three-dimensional sense and charm of the eyes.
Skin Care Products
Application Scenarios: Some high-end skin care products also add trace amounts of metallic pigments to increase
the visual appeal and luxury of the product.
Function: Metallic pigment dispersants can ensure that metallic pigments are stably dispersed in skin care products,
without adversely affecting the safety and stability of the product. At the same time, it can also make skin care
products have a certain gloss effect when applied, improving the quality of the product.
For example, adding metallic pigments treated with dispersants to a high-end facial cream can give the cream a
delicate luster in the bottle and also provide a slight brightening effect when applied to the face.
