Description

1,2-Ethanediamine, n-(2-Aminoethyl)-, Polymer With (Chloromethyl)Oxirane And n-Methylmethanamine is a specialized polyamine-based polymer, known commercially as a polyamidoamine-epichlorohydrin (PAE) resin. This compound is a high-performance cationic polymer valued for its exceptional wet-strength enhancement and retention properties in aqueous systems. It is a critical material for manufacturers in the paper and water treatment industries seeking to improve product durability and process efficiency.

Application

• Wet-Strength Resin for Paper & Packaging: Primary application as a permanent wet-strength additive for tissue, towel, filter media, and specialty paper grades, significantly improving paper integrity when wet.
• Retention & Drainage Aid in Papermaking: Functions as a cationic flocculant to improve fine particle and filler retention on the paper machine wire, enhancing yield and water drainage rates.
• Wastewater Treatment Flocculant: Used as an organic coagulant aid and flocculant for clarifying industrial and municipal wastewater by aggregating suspended solids and organic matter.
• Crosslinking Agent for Polymers: Serves as a reactive crosslinker in the synthesis of epoxy resins, adhesives, and coatings to modify mechanical and thermal properties.
• Textile & Fiber Treatment: Applied as a modifier to improve dye affinity, anti-static properties, and durability of synthetic and natural fibers.
• Personal Care Product Stabilizer: Utilized in select hair care and cosmetic formulations as a conditioning and viscosity-modifying agent.

Quality Control

Our Polyamidoamine-epichlorohydrin (PAE) resin is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing for key parameters including cationic charge density, solids content, viscosity, and residual epichlorohydrin to ensure consistent performance and compliance with industry and regulatory standards. Comprehensive Certificates of Analysis (COA) documenting all specifications are provided with every shipment.

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 light-sensitive (store away from light) and has a strong alkali character; avoid contact with acids and incompatible materials. Keep container tightly sealed when not in use to prevent moisture absorption and contamination.
