Products Description
Sodium salt of polynaphthalene sulphonic acid, 2-Naphthalenesulfonic acid, polymer with formaldehyde, sodium salt; FORMALDEHYDE-2-NAPHTHALENESULFonIC ACID-SODIUM SALT POLYMER;Naphthalenesulfonic acid/formaldehyde condensation product;2-naphthalenesulfonic acid/ formaldehyde sodium salt, Dispersant NNO

Products Performance
Sodium salt of polynaphthalene sulphonic acid Dispersant NNO has excellent diffusivity and protective colloid properties, but no surface activity such as penetration and foaming. It has affinity for protein and polyamide fibers, but no affinity for cotton, linen and other fibers.
Products Uses
- Sodium salt of polynaphthalene sulphonic acid Dispersant NNO is mainly used as a dispersant in disperse dyes, vat dyes, reactive dyes, acid dyes and leather dyes, with excellent grinding effect, solubility and dispersibility; it can also be used as a dispersant for textile printing and dyeing, wettable pesticides, papermaking dispersants, electroplating additives, water-soluble coatings, pigment dispersants, water treatment agents, carbon black dispersants, etc.
- Sodium salt of polynaphthalene sulphonic acid Dispersant NNOis mainly used in industry for pad dyeing of vat dye suspensions, leuco acid dyeing, and dyeing of dispersed and soluble vat dyes. It can also be used for dyeing silk/wool interwoven fabrics to make the silk colorless.
- Sodium salt of polynaphthalene sulphonic acid Dispersant NNO is mainly used in the dye industry as a diffusion aid in the manufacture of dispersion and color lakes, rubber emulsion stability, and leather tanning aid.
Products Description
Printing and dyeing industry
Sodium salt of polynaphthalene sulphonic acid Dispersant NNO is mainly used for pad dyeing of vat dye suspension, leuco acid dyeing, dyeing of dispersed and soluble vat dyes, etc. It can also be used for dyeing silk/wool interwoven fabrics to make silk without coloring. In the dye industry, it is mainly used as a dispersant and diffusion aid in the manufacture of color lakes.
Building materials industry
Sodium salt of polynaphthalene sulphonic acid Dispersant NNO is used as cement water-reducing and early strength agent, the dosage is 0.5-1%. After cement vibration, the cement has a good dispersion effect and enhances the strength of cement. Dispersant N improves the tensile, impermeability, frost resistance and compressive elastic modulus of concrete, and has no corrosion effect on steel bars.
Agricultural industry
Sodium salt of polynaphthalene sulphonic acid Dispersant NNO can be widely used in wettable pesticides, has good dispersing and solubilizing effects, and can significantly improve the efficacy. The dosage can be determined according to product requirements. For example: cypermethrin, the dosage is 3-5%; the dosage of thiophanate-methyl is 0.8-1.5%, and the dosage of cypermethrin is 0.8-1%.
Electroplating industry
Adding Sodium salt of polynaphthalene sulphonic acid dispersant NNO in color electroplating can make the pigment dispersed evenly and significantly improve the brightness of the electroplated surface. The dosage is generally 10% of the pigment.
Rubber industry
In the production process of rubber (latex) industry. For dispersed substances such as liuhuang accelerators, antioxidants, zinc oxide fillers (such as barium sulfate, calcium carbonate), etc., it can improve the dispersion effect and shorten the ball milling time. Add 2-4% dispersant NNO to the dry powder weight, make the dispersant into a 10% solution in advance, and then grind it in a ball mill with other components to improve the dispersion effect and shorten the ball milling time.
