• Product description :

  Appearance: Beige brown solid Moisture:≦8% PH value:7-9 Diffusibility:≧95% Application property: 1.This chemical is acid-resisting, alkali-resisting, heat-resisting and resistant to hard water and mineral salt. 2. While using together with anion and non-ionic surfactants, it is of good diffusivity and colloid protecting property without penetration and foamability and other surfactants. 3. It is mainly used in pigment pad dyeing of vat dyes, vat acid dyeing and dyeing of dispersive and soluble vat dyes, etc. It also can be used in dyeing of silk-wool fabrics to make silk without coloring. 4. It can be used as dispersing aid, rubber emulsion stabilizer and leather auxiliary tanning agent during disperison and lake manufacture.
