(III) PERFORMANCE AND USE
The dispersing agent MF is mainly used as dispersing agent and filler for vat dyes and disperse dyes. It is mainly ，
used for disperse dyes and finishing agents and dispersants when vat dyes are lapping, and its performance is better than dispersant N. The dispersant MF has the advantages of good grinding efficiency, dispersibility, heat resistance,
dispersion stability in high temperature. It is more resistant to high temperature and stable than the dispersant N.
The dispersing agent MF can make the dye more brightly and colourful, increase color force, and uniform coloring.
The dispersing agent MF can also be mixture formulation with all kinds of dispersants in order to adapt to the various commercial requirements of disperse dyes and vat dyes;can be used as concrete early strength superplasticizer; can be used as dispersing agent both in during grinding vat dyestuff and during dyeing with vat dye suspension; and stabilizer in rubber&latex industry, auxiliary tanning agent in leather industry.
