Application of matte dispersants

Application of matte dispersants

Matte dispersants are widely used in the processing of materials such as coatings, inks, plastics, cosmetics and ceramics, especially in the field of coatings and inks.

The core function of matte dispersants is to reduce the surface tension of pigments or fillers and promote their uniform dispersion in the matrix, thereby improving the matte effect, stability and processing performance of the material. The following is an analysis of specific application areas:

1. Coatings industry

Application scenarios: matte coatings, industrial coatings, wood coatings, automotive coatings, etc.

Function:

Improve matte effect: reduce gloss by controlling the arrangement of pigment particles and forming a uniform matte surface.

Improve stability: prevent pigment sedimentation or agglomeration and extend the storage period of coatings.

Optimize construction performance: reduce coating viscosity, improve leveling, and reduce brush or roller marks.

Typical case: In UV-cured matte coatings, dispersants can ensure that pigments are evenly dispersed during the light curing process to avoid uneven gloss caused by pigment aggregation.

2. Ink industry

Application scenarios: matte inks, packaging inks, label inks, etc.

Function:

Enhance matte texture: make the surface of printed products present a soft matte effect, improve touch and visual grade.

Improve printing quality: prevent pigments from settling in ink, ensure the clarity and consistency of printed patterns.

Improve drying performance: some dispersants can promote rapid drying of inks and improve production efficiency.

Typical case: in food packaging inks, matte dispersants can achieve low gloss while meeting food safety standards.

3. Plastics industry

Application scenarios: matte plastic products (such as home appliance housings, car interiors), plastic films, etc.

Function:

Give matte surface: the filler (such as talcum powder, calcium carbonate) in the plastic is evenly dispersed through the dispersant to form a matte effect.

Enhance mechanical properties: improve the impact resistance and wear resistance of plastics.

Improve processing performance: reduce melt viscosity, easy to extrusion or injection molding.

Typical case: in home appliance housing plastics, matte dispersants can achieve matte surface and anti-fingerprint effect.

4. Cosmetics industry

Application scenarios: matte lipstick, foundation, eye shadow, etc.

Function:

Provide matte makeup effect: make cosmetics present a soft matte texture and avoid oily shine.

Enhance adhesion: promote the combination of pigment and matrix, and improve the durability of makeup.

Improve skin feel: make the product smooth and non-caking.

Typical case: In matte lipstick, dispersants can ensure that the pigment is evenly dispersed to avoid color spots or makeup removal after application.

5. Ceramic industry

Application scenarios: matte ceramic glaze, ceramic ink, etc.

Function:

Achieve matte glaze: The metal oxides in the glaze are evenly dispersed through dispersants to form a matte effect.

Improve firing stability: prevent cracks or bubbles from appearing in the glaze during high-temperature firing.

Optimize printing performance: In ceramic ink, dispersants ensure the clarity and color saturation of the pattern.

Typical case: In architectural ceramic glazes, matte dispersants can achieve low gloss while enhancing the wear resistance of the glaze.

6. Other fields

Paper coating: used in the production of matte paper to improve the touch and printing adaptability of paper.

Leather treatment: give leather a matte texture and enhance its high-end feel.

Textile coating: used for matte coated fabrics to provide a low-gloss surface effect.

Application selection points

Material compatibility: Dispersants must be compatible with base materials (such as resins, solvents) to avoid affecting the final performance.

Dispersion effect: The appropriate type of dispersant (such as polymer type, small molecule type) must be selected according to the pigment particle size and system viscosity.

Environmental regulations: In food contact materials or children's products, dispersants that meet environmental standards must be selected.
