Dispersant MF is used as dispersant and filler for VAT dyes and disperse dyes
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.

Use:
Dispersant MF is mainly used as a dispersant and filler for vat dyes and disperse dyes. It is mainly used as a processing agent and dispersant for grinding of disperse dyes and vat dyes. Its performance is better than that of dispersant N. Dispersant MF has the advantages of good grinding efficiency, good dispersibility, heat resistance, and high temperature dispersion stability. Higher temperature resistance and stability than dispersant N. The dispersing agent MF can make the dye bright in color, increase in color strength, and even in coloring. The dispersant MF can also be compounded with various dispersants to meet the commercial requirements of various disperse dyes and vat dyes; it can also be used as an early strength water-reducing agent for concrete; it can be used as a dispersant and vat dye when grinding Dispersant for vat dye suspension dyeing; and stabilizer for latex in rubber industry, tanning aid for leather industry.
1. The dispersant MF is used for reduction, and the disperse dye is used as a grinding dispersant and a filler during standardization, and can also be used as a diffusing agent during the manufacture of Sedian.
2. The dispersant MF is mainly used in the printing and dyeing industry for pad dyeing of vat dye suspensions, dyeing and dispersion by stable color acid method, and dyeing of soluble vat dyes.
3. Dispersant MF is used as a tanning aid in the leather industry, and as a stabilizer for latex in the rubber industry.
4. Dispersant MF can be dissolved in concrete as a strong water-reducing agent, which can shorten the construction period, save cement, save water and increase the strength of cement.
Usage:
According to the recipe, pour the dispersant MF into the sand mill for sand milling. After the sand milling, add other ingredients for the next process. The liquid dispersant should be fully stirred before use, and mixed well and put into a sand mill.
