Description

Phenol, 4,4-(1-Methylethylidene)Bis-, Polymer With N,n-Bis(2-Aminoethyl)-1,2-Ethanediamine And (Chloromethyl)Oxirane is a specialized, high-performance polymer derived from bisphenol A, a polyamine, and epichlorohydrin, forming a reactive polyaminoamide-epichlorohydrin resin. This compound is engineered to deliver superior performance as a wet-strength additive and retention aid in paper manufacturing, directly addressing the need for improved paper durability and production efficiency. It is a critical raw material for paper mills, specialty adhesive formulators, and water treatment chemical producers seeking to enhance product performance and process reliability.

Application

• Wet-Strength Resin for Paper & Packaging: Primary application as a cationic wet-strength agent to significantly improve the tensile strength of paper and paperboard when wet, essential for packaging, towels, and filtration media.
• Retention and Drainage Aid: Functions as a flocculant and retention aid in papermaking processes to improve fiber and filler retention, enhancing sheet formation and reducing white water system load.
• Specialty Adhesive Formulations: Used as a curing agent or modifier in epoxy-based adhesive systems, contributing to improved toughness and chemical resistance.
• Surface Sizing and Coating: Employed in surface sizing formulations to improve printability, water resistance, and surface strength of paper.
• Wastewater Treatment: Acts as an organic coagulant aid or flocculant in the treatment of industrial wastewater, particularly for systems containing organic colloids.
• Textile Processing Auxiliary: Utilized as a cross-linking agent or finish to impart durable press properties or water repellency to textiles.

Quality Control

Our Polyaminoamide-epichlorohydrin (PAE) resin is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance characteristics such as solids content, viscosity, charge density, and reactivity. Certificates of Analysis (COA) documenting key specifications are provided with every shipment to guarantee supply reliability and product consistency for your critical manufacturing processes.

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). This product is hygroscopic (moisture-sensitive). Keep container tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product performance. Do not freeze. For long-term storage, consider using under an inert atmosphere.
