What is Dispersing Agent NNO?

Dispersing Agent NNO is light yellow to yellow-brown powder, an anion surface active agent, which has excellent diffusive and protective colloid performance, Easily soluble in water, acid, alkali and hard water. It has good dispersing property and affinity with protein and polyamide.
Dispersing Agent NNO is easily soluble in water, resistant to acid, alkali, salt and hard water, and has good diffusion properties.Dispersing Agent NNO is mainly used as a dispersant in disperse dyes, vat dyes, reactive dyes, acid dyes and leather dyes.Dispersing Agent NNO has excellent grinding effect, solubilization and dispersibility.Dispersing Agent NNO can also be used as a dispersant for textile printing and dyeing, wettable pesticides, and a dispersant for papermaking. Electroplating additives, latex, rubber, construction, water-soluble paint, pigment dispersant, petroleum drilling, water treatment agent, carbon black dispersant, etc.

Application

1) Printing and dyeing industry:Dispersing Agent NNO is mainly used for reducing dye suspension, dyeing, dispersing and dyeing of soluble VAT dyes. Dispersing Agent NNO can also be used for dyeing silk/wool interwoven fabric, which makes the silk uncolored. In dye industry Dispersing Agent NNO is mainly used as dispersant and dispersant agent.
2) Building materials industry: Dispersing Agent NNO is mainly 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.
3)Agricultural industry:Dispersing Agent NNO can be widely used in wet pesticide, has good dispersion and solubilization, can obviously improve the efficiency.
4) 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.
5) 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.
6) Paper industry: Water-soluble paint, pigment dispersant, water treatment agent, carbon black dispersant.
