Description

Hexanedioic Acid, Polymer With n-(2-Aminoethyl)-1,2-Ethanediamine, (Chloromethyl)Oxirane, Formaldehyde And Formic Acid is a specialized cationic polymer resin, commonly known as a polyamide-epichlorohydrin (PAE) resin, with the CAS registry number 76649-45-1. This high-performance polymer is engineered to provide exceptional wet-strength and retention properties in aqueous systems. It is a critical chemical for industries requiring durable, water-resistant paper and board products, as well as efficient process aids in water treatment and mineral processing. Its multifunctional nature makes it a versatile additive for enhancing material performance across several manufacturing sectors.

Application

• Wet-Strength Agent for Paper & Packaging: Primarily used in the production of tissue, towel, filter papers, and liquid packaging board to significantly improve tensile strength when wet.
• Retention & Drainage Aid: Enhances the retention of fine particles, fillers, and fibers in papermaking, improving process efficiency and product quality.
• Flocculant for Water Treatment: Employed in municipal and industrial wastewater treatment to aggregate suspended solids for easier separation and clarification.
• Mineral Processing: Acts as a selective flocculant or depressant in the beneficiation of ores such as kaolin and phosphates.
• Textile & Non-Woven Binder: Provides binding strength in the manufacture of non-woven fabrics and textiles.
• Crosslinking Agent for Coatings: Used in specific coating formulations to improve water resistance and durability.

Quality Control

Our polyamide-epichlorohydrin (PAE) resins are manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Each lot undergoes rigorous quality testing, including analysis of active solids content, viscosity, charge density, and functional group concentration. Certificates of Analysis (COA) documenting these key specifications are available upon request. Our quality management system is designed to meet the demanding requirements of the paper, packaging, and water treatment industries.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). Keep away from heat, sparks, and open flame. This product is light-sensitive (store away from light). For long-term storage, ensure containers are sealed to prevent moisture absorption and skin formation.
