dispersant

1. Coatings industry

Dispersion of pigments and fillers: This is one of the most core applications of dispersants. In various coatings such as paints, latex paints, and powder coatings, dispersants are used to effectively disperse inorganic pigments (such as titanium dioxide, iron oxide, and carbon black) and organic pigments and extender pigments (such as calcium carbonate and talcum powder) in resins or solvents, preventing sedimentation, color floating, and mottling, enhancing tinting strength, covering power, and gloss, and ensuring the storage stability of the coatings.

Reduce viscosity: Make high-solid content coatings easier to apply.

Improve grinding efficiency: Shorten the pigment grinding time and reduce energy consumption.

2. Ink industry

Pigment dispersion: Similar to coatings, in printing inks (offset inks, gravure inks, flexographic inks, inkjet inks, ແລະອື່ນໆ), dispersants are used to stabilize pigment particles, ensuring the color saturation, printing clarity, storage stability of the ink, and preventing the inkjet print head from clogging.

Control rheological properties: Improve the printability of ink.
