Description

Hexanedioic Acid, Polymer With n-(2-Aminoethyl)-1,2-Ethanediamine, Ammonia, (Chloromethyl)Oxirane, Formaldehyde And Formic Acid CAS NO 76649-35-9 is a specialized cationic polyamine-epichlorohydrin resin, engineered for superior performance as a wet-strength agent and retention aid. This polymer is critical for enhancing the mechanical properties and process efficiency of paper and board products. It is an essential material for manufacturers in the pulp and paper, water treatment, and specialty chemical industries seeking to improve product quality and operational yield.

Application

• Wet-Strength Agent in Papermaking: Primary application for imparting high wet tensile strength to tissue, towel, packaging, and specialty papers.
• Retention and Drainage Aid: Improves fiber and filler retention in the paper sheet and enhances water drainage on the wire, increasing machine speed and efficiency.
• Flocculant in Water Treatment: Used for the clarification of process water, wastewater, and sludge dewatering due to its strong cationic charge and bridging capabilities.
• Strength Additive for Nonwovens: Provides integrity and durability to air-laid and wet-laid nonwoven fabrics.
• Surface Sizing and Coating Binder: Enhances surface strength, printability, and glueability of paper and board.
• Fixing Agent for Anionic Trash: Neutralizes and fixes dissolved and colloidal anionic substances (DCS) in paper mill systems to reduce deposits and improve runnability.

Quality Control

Our polyamine-epichlorohydrin resins are manufactured under a stringent quality management system to ensure batch-to-batch consistency and performance reliability. Each lot is tested for critical parameters including solids content, viscosity, charge density, and functional activity. Certificates of Analysis (COA) documenting full specifications are provided with every shipment. Our production adheres to relevant ISO standards, and the product is compliant with global regulations including FDA 21 CFR 176.170 for use in paper and paperboard in contact with aqueous and fatty foods.

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). Do not freeze. This product is sensitive to strong alkali and organic solvents; store away from such materials. As it is easily oxidized, prolonged storage under an inert atmosphere (e.g., nitrogen) is recommended for optimal shelf life. Keep container tightly sealed when not in use to prevent moisture absorption and skin formation.
