ashless dispersant Surfactant

The ashless dispersant is a surfactant that has both lipophilic and hydrophilic properties in the molecule at the same time. It is possible to uniformly disperse the solid particles of inorganic and organic pigments which are difficult to dissolve in the liquid, and also to prevent the settling and agglomeration of the solid particles and to form the medicament required to stabilize the suspension. The use of wetting ash dispersant to reduce the time and energy required to complete the dispersion process, stabilize the dispersed pigment dispersion, modified pigment particle surface properties, adjust the movement of pigment particles, embodied in the following aspects: shorten the dispersion time , Improve the gloss, improve the color strength and hiding power, improve color rendering and color, to prevent floating color flowers, to prevent flocculation, to prevent settlement.

  The specific performance of the ashless dispersant is as follows:

1, adsorbed on the surface of solid particles, reducing the liquid-liquid or solid-liquid interface between the tension. So that the surface of the agglomerated solid particles is easy to wet.

2, the polymer type of ashless dispersant, in the solid particles on the surface of the formation of adsorption layer, the solid particles on the surface of the charge increases, to improve the formation of three-dimensional barrier between the reaction force between the particles.

3, the surface of the solid particles to form a bilayer structure, the outer layer of ash dispersant polar end and water have a strong affinity, increasing the degree of solid particles wet by water. Solid particles are separated by electrostatic repulsion.

4, so that the system uniform, suspended performance increases, do not precipitate, so that the same physical and chemical properties of the same system.

  Ashless dispersant, also known as wetting ash dispersant, is a surfactant that can be in the molecule at the same time with lipophilic and hydrophilic two opposite nature of the effective dispersion of microorganisms in the solvent, through the basic principles or a certain mechanism, Various solids form a very stable suspension of the required medicament.

        The ashless dispersant is a surfactant that has both lipophilic and hydrophilic properties in the molecule at the same time. It is possible to uniformly disperse the solid particles of inorganic and organic pigments which are difficult to dissolve in the liquid, and also to prevent the settling and agglomeration of the solid particles and to form the medicament required to stabilize the suspension. In the paint production process, pigment dispersion is a very important production process, it is directly related to the storage of paint, construction, appearance and performance of the film, so a reasonable choice of ash-free dispersant is a very important part of the production.
