water decoloring agent LSD-01

CAS No.: 55295-98-2

Product Name: LSD-01 decolorant polymer

Chemical Name: Dicyandiamide condensation resin (PolyDCD)


  1. Lansen is the biggest manufacturer of water decoloring agent in world.
  2. LSD-01 Water Decoloring Agent is cationic polyelectrolyte, which has high color removal of dye wastewater, by providing a large number of cations, the negative charge is brought on dye molecules are neutralized instability, at the same time with BWD-01 Water Decoloring Agent by a large number of hydrolysis of flocs. Can be adsorbed dye, destabilization of the snare, from water separation, so as to achieve the purpose of bleaching.
  3. It is specially working high performance with the dyeing wastewater containing the hydrophilic dyes (reactive dyes, acid dyes, disperse dyes etc.), less dosage, the color clear, fast speed, high processing liquid clarification of the settlement, but also reduce the composition of COD, improve the COD removal rate.
  4. Soluble in water, safe, non-toxic, hydrolytic stability, is not sensitive to the change of pH value, anti-chlorine. Harmless, no-flammable and non-explosive, it can be stored at room temperature, it cannot be placed in the sun. It is slightly acidic, when skin contact, wash immediately with plenty of water.
