Description

Methanamine, n-Methyl-, Polymer With Ammonia And (Chloromethyl)Oxirane CAS NO 52722-38-0 is a specialized cationic polymer, specifically a polyamine-epichlorohydrin resin, known for its high charge density and reactivity. This compound is valued for its exceptional performance as a flocculant, retention aid, and wet-strength agent in demanding industrial processes. It is a critical raw material for manufacturers in the paper and pulp, water treatment, and textile industries seeking to improve process efficiency and product performance.

Application

• Paper and Pulp Manufacturing: Primary use as a wet-strength resin to significantly improve the dry and wet tensile strength of paper products like towels, tissues, and packaging board.
• Wastewater Treatment: Acts as a highly effective cationic flocculant for clarifying industrial and municipal wastewater by agglomerating suspended solids and organic matter.
• Retention and Drainage Aid: Enhances the retention of fine particles and fillers in papermaking, improving sheet formation and reducing raw material costs.
• Textile Processing: Used as a fixing agent and dye retention aid to improve color fastness and reduce dye migration.
• Sugar Refining: Employed as a clarifier to remove impurities and colorants from sugar syrups during the refining process.
• Oil & Gas Industry: Functions as a clay stabilizer and fluid loss control additive in drilling mud formulations.

Quality Control

Our production of Polyamine-epichlorohydrin resin adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including charge density, viscosity, solids content, and residual epichlorohydrin to meet industry specifications. Certificates of Analysis (COA) documenting these results are 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, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). This product is hygroscopic (moisture-sensitive) and should be kept away from strong oxidizing agents and acids. For long-term storage, ensure containers are sealed to prevent moisture absorption and skin formation.
