Don't know about water-based paint dispersants?

Dispersant is the reasonable dispersion of various powders in the solvent, through a certain charge repulsion principle or polymer steric effect, so that all kinds of solids are stably suspended in the solvent (or dispersion). Aqueous dispersant is a kind of interfacial active agent which has two opposite properties of oleophilic and hydrophilic in the molecule. It can uniformly disperse solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquids.

Aqueous coating dispersant is a kind of interfacial active agent which has two opposite properties of oleophilic and hydrophilic in the molecule. It can uniformly disperse the solid and liquid particles of inorganic and organic pigments that are difficult to dissolve in liquid, and also prevent the sedimentation and condensation of particles to form amphiphilic reagents required for stable suspension. The water-based coating dispersant has non-foaming property, which can increase the coating film defects and the amount of defoamer. At the same time, it can also reduce the grinding viscosity, improve operability, maintain the stability of latex viscosity, and avoid pigment deposition and consolidation. If used with non-ionic wetting agent, wetting, dispersing effect and good stability to avoid color separation and floating color. Water-based paint dispersant, suitable for a variety of water-based systems, such as latex paint, adhesive, textile paste, paper manufacturing paint, water-based ink, etc.

The function of water-based coating dispersant is to use wetting water-based coating dispersant to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modify the surface properties of the pigment particles, and adjust the movement of the pigment particles. In the process of coating production, pigment dispersion is a very important production link, which is directly related to the storage and construction of the paint. The appearance and the performance of the paint film, etc., so the reasonable selection of paint dispersant is a very important production link. However, the dispersion of the coating slurry is not only related to the dispersant, but also to the formulation of the coating formula and the selection of raw materials.
