USE:
The chemical names of dispersant NNO are sodium methylenedinaphthalene sulfonate and sodium methylenedinaphthalene sulfonate, which have excellent diffusivity and protective colloidal properties, but have no surface activity such as osmotic foaming, affinity for protein and polyamide fibers, and affinity for cotton and linen fibers. It is mainly used as dispersant in disperse dyes, VAT dyes, reactive dyes, acid dyes and leather dyes, with excellent abrasion, solubilization and dispersibility. It can also be used as dispersant in textile printing and dyeing, wettable pesticides, dispersant for papermaking, electroplating additives, water-soluble coatings, pigment dispersant, water treatment agent, carbon black dispersant, etc. Dispersant NNO is mainly used in industry for pad dyeing of vat dyes suspension, leuco acid dyeing, dispersibility and dyeing of soluble VAT dyes, etc. It can also be used for dyeing silk/wool interwoven fabrics to make silk colorless.
