Description

Guanidine, Cyano-, Polymer With Formaldehyde, Ammonium Chloride-Modified is a specialty cationic polymer, a modified polycondensate of cyanoguanidine (dicyandiamide) and formaldehyde, widely used as a highly effective flocculant and retention aid. Its modified cationic structure provides superior performance in clarifying process water and improving the efficiency of solid-liquid separation across multiple industries. This product is essential for manufacturers and treatment facilities seeking to enhance process yields, reduce waste, and meet stringent environmental discharge standards.

Application

• Wastewater Treatment: Primary flocculant for the clarification of industrial and municipal wastewater, effectively removing suspended solids and colloidal particles.
• Paper & Pulp Industry: Key retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing sheet formation and reducing BOD/COD in white water.
• Textile Processing: Used in effluent treatment to remove dyes and other organic contaminants from dyeing and finishing bath discharges.
• Mining & Mineral Processing: Clarification of process water and tailings ponds, aiding in the settling of fine mineral particles and slimes.
• Sugar Refining: Clarification agent in juice purification processes to remove non-sugar impurities, improving filtration rates and sugar quality.
• Oilfield Applications: Water clarification agent in produced water treatment and drilling mud dewatering operations.

Quality Control

Our production of Guanidine, Cyano-, Polymer With Formaldehyde, Ammonium Chloride-Modified adheres to strict internal quality protocols to ensure batch-to-batch consistency and performance reliability. Each lot is tested for critical parameters including cationic charge density, viscosity, solids content, and pH to meet defined application specifications. A Certificate of Analysis (COA) documenting these results is provided with every shipment to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure containers are sealed immediately after use to prevent moisture absorption and caking. Keep away from strong oxidizing agents.
