Alcohol-soluble dispersants are a type of chemical additives that can effectively disperse solid particles or
droplets in alcohol solvents. They are widely used in many industrial fields such as coatings, inks, pesticides,
plastics, and ceramics.
1. Coatings Industry
Pigment Dispersion
Alcohol-soluble dispersants reduce the surface tension between pigment particles, prevent agglomeration, and
improve the wettability and dispersibility of pigments. For example, in alkyd resin coatings, dispersants can evenly
disperse pigments and avoid sedimentation, thereby improving the coloring power and gloss of the coating.
Storage Stability
Dispersants can enhance the storage stability of coatings, prevent pigment particles from flocculating or precipitating
during long-term storage, and ensure that the coating maintains uniform and consistent performance during use.
2. Ink Industry
Printability
In alcohol-soluble inks, dispersants can improve the dispersion effect of pigments, improve the fluidity and printability of
inks, and make printed patterns clearer and more uniform.
Anti-precipitation
Dispersants can prevent pigment particles in inks from precipitating during storage or use, ensuring the stability of inks and
printing quality.
3. Pesticide industry
Preparation stability
Alcohol-soluble dispersants are used to disperse the active ingredients of pesticides in pesticide preparations, improve the
suspension and stability of pesticides, prevent the precipitation of active ingredients, and extend the shelf life of pesticides.
Efficacy improvement
By improving the dispersibility of pesticide particles, dispersants can improve the bioavailability of pesticides, enhance efficacy,
and reduce the amount of pesticides used.
4. Plastic industry
Filler dispersion
In plastic processing, dispersants are used to disperse inorganic fillers (such as calcium carbonate, talcum powder, etc.), improve the
compatibility of fillers and resins, and improve the mechanical properties and processing properties of plastics.
Enhanced performance
Dispersants can reduce the agglomeration of fillers and improve the uniformity of filler dispersion, thereby enhancing the strength,
toughness and wear resistance of plastics.
5. Ceramic industry
Slurry dispersion
In ceramic production, alcohol-soluble dispersants are used to disperse ceramic powders, reduce the viscosity of slurries, improve the
fluidity and stability of slurries, and facilitate molding and sintering.
Product density
Dispersants can prevent ceramic powders from agglomerating during drying and sintering, and improve the density and mechanical
properties of ceramic products.
6. Other applications
Electronic materials
In electronic slurries, dispersants are used to disperse conductive particles (such as silver powder, copper powder, etc.) to improve the
uniformity and conductivity of the slurry.
Cosmetics
In alcohol-soluble cosmetics, dispersants are used to disperse pigments and functional particles to improve product stability and use effects.
