  Dispersant NNO 
  YL-NNO Sodium Naphthalene Sulfonate Condensate
  CAS NO.: 36290-04-7
   
  Description 
  YL-NNO is light brown yellow powder, an anion surface active agent. Easily soluble in water, acid, alkali and hard water. It has good dispersing property and affinity with protein and polyamide.
   
  Usage
  Mainly used for vat dye dyeing, reactive dye dyeing and acid dye dyeing. It can work as dispersant for acid staining pad and pigment pad dyeing; auxiliary for reducing dye powder and slurry. It can also be used in leveling agent in dyeing industry 
   
  Advantages
  1). As dispersant NNO in disperse dye, vat dye, reactive dye, acid dye and leather dye. It has good
  grinding effect, hydrotropy and dispersibility.
  2). As dispersant in textile printing and dyeing industry: pigment pad dyeing of disperse dye;vat
  acid dyeing of disperse dye; dye for silk and feather mixture; soluble vat dye dyeing; Etc. Also
  can be used as dispersant for disperse dye and lake making; filler for commercial dye etc.
  3). As dispersant in wettable pesticide and herbicide, the dispersibility and solubility of pesticide
  can be improved.
  4). As dispersant in electroplating industry, so that the cladding film can be equal and have a
  better brightness.
  5). As auxiliary tanning agent in leather industry, used together with tanning agent (ratio 1:10) to
  avoid tanning agent stick with leather. Can also help to disperse dye to get a better
  appearance in color.
     6). As dispersant for paper industry. After adding NNO into wood pulp to avoid the stain from the
  condensation of asphaltum, resin and other material, 0.2%-0.5% of the wood pulp’s weight as
  dosage is preferable. Can work as precipitator for animal size, 20%-30% of the size’s weight as
  dosage is preferable.
  7) . As dispersant in rubber industry. Can disperse sulfur, accelerant, anti-aging agent and some
  filler(like zinc oxide, barium sulphate, calcium carbonate etc). 2%-4% of the dry powder’s
  weight as dosage is preferable. Can make NNO into 10% solution, then grind with others in ball
  grinder.
  8). Also can be used in coating, painting, pigment, carbon black etc.
  9). Can be used in color lake industry.
