Dispersant MF has good dispersibility and stability, and the content of quinoline is very low
Dispersing agents, also called dispersant additives, are to reasonably disperse various powders in the solvent, through a certain charge repulsion principle or polymer steric hindrance effect, so that various solids are stably suspended in the solvent (or dispersion). Dispersant is a kind of surfactant with two opposite properties of lipophilicity and hydrophilicity at the same time in the molecule. It can evenly disperse the solid particles of inorganic and organic pigments that are difficult to dissolve in liquids, and at the same time, it can prevent the sedimentation and agglomeration of the solid particles, and form the medicine required for the stable suspension.
In the coating production process, pigment dispersion is a very important production link, which is directly related to the storage, construction, appearance and performance of the paint film, so the reasonable selection of dispersant is a very important production link. However, the quality of the dispersion of the coating slurry is not only related to the dispersant, but also has a certain relationship with the formulation of the coating formulation and the selection of raw materials.

Dispersing agent MF is an anionic surfactant with excellent diffusibility and thermal stability. It is a brown powder, soluble in water, absorbs moisture, non-combustible, non-permeable, or foaming. And it resists acid, alkali, hard water, and inorganic salt. Dispersant MF has an affinity for protein and polyamide fibers, but no affinity for cotton, flax, or other fibers. It can mix with both anionic and nonionic surfactants, but can not mix with cationic dyes or surfactants.
