Solubility: the product has good solubility, dispersant NNO is soluble in any hard water, anionic type; 

Stability: acid resistance, alkali resistance, heat resistance, hard water resistance, inorganic salt, good stability

Performance: The dispersant N has excellent diffusivity and protective colloid properties, but no permeability and foaming ability known as surface activity, therefore it has affinity to the protein and polyamide fiber, no affinity to cotton and hemp. With 1% alkaline aqueous solution, which has ionization, anionic sex and affinity, can be mixed with anionic and non-ionic surfactants used at the same time


Diffusion rate (for standard products):100% min

PH value (1% aqueous solution): 7-9

Sodium sulfate content: 5% max

Calcium and magnesium ion content: 0.4% max

Insoluble substance: 0.05% max


Printing and dyeing industry: Mainly used for reducing dye suspension, dyeing, dispersing and dyeing of soluble VAT dyes. It can also be used for dyeing silk/wool interwoven fabric, which makes the silk uncolored. In dye industry is mainly used as dispersant and dispersant agent.

Building materials industry: Used as an early strength cement to reduce water, which makes cement has good dispersion effect after cement shock, strengthen cement strength, shorten construction period, save cement and save water. The dispersant NNO has improved the tensile, anti-seepage, antifreeze and compressive elastic modulus of the mixed soil.

Agricultural industry: Can be widely used in wet pesticide, has good dispersion and solubilization, can obviously improve the efficiency.

Electroplating industry: the addition of dispersant NNO in color electroplating can disperse the pigment uniformly, which can obviously improve the brightness of the electroplating surface.

Rubber industry: in the production process of rubber (latex) industry. For dispersing materials such as sulphur promoters, antioxidant zinc oxide fillers (such as barium sulfate and calcium carbonate), the dispersion effect can be improved and the ball milling time can be shortened.

Paper industry: dispersants used in paper industry.

Water-soluble paint, pigment dispersant, water treatment agent, carbon black dispersant.
