BWD-01 Dicyandiamide Polymer Decolorizing Agent for Indigo Dye Wastewater, CAS 55295-98-2
Industrial-grade liquid cationic polymer decolorizing agent offered for textile, dye house, pigment, ink, and paper wastewater applications where indigo dye color removal and COD reduction are part of the buyer’s treatment specification. Overseas buyers should confirm CAS identity, active/solid content, viscosity range, pH, impurity profile, transport classification, export documentation, and suitability through jar testing or site-specific performance evaluation before RFQ placement.
