Description

Guanidine, Cyano-, Polymer With Formaldehyde, Methylated is a synthetic, cationic polymer derived from the condensation of cyanoguanidine (dicyandiamide) with formaldehyde and subsequent methylation. This compound is valued for its strong cationic charge and ability to function as a highly effective flocculant and retention aid in aqueous systems. It is primarily utilized by industries requiring advanced water treatment solutions and process efficiency enhancements, such as paper manufacturing, mining, and municipal wastewater treatment.

Application

• Paper Manufacturing: Acts as a powerful retention and drainage aid, improving fiber and filler retention on the paper machine wire for enhanced production efficiency and paper quality.
• Water & Wastewater Treatment: Serves as a primary coagulant and flocculant for clarifying process water, industrial effluent, and municipal wastewater by agglomerating suspended solids.
• Mining & Mineral Processing: Used in solid-liquid separation processes, such as tailings dewatering and concentrate thickening, to accelerate settling rates and produce clearer water.
• Textile Industry: Employed as a fixing agent and dye retention aid, improving color fastness and reducing dye migration during textile processing.
• Sugar Refining: Assists in the clarification of sugar juice by precipitating impurities, leading to improved sugar yield and quality.
• Oil & Gas Industry: Functions as a clarifier and dewatering agent in drilling mud and produced water treatment systems.
