Description

Octadecanamide, N,N'-(Iminodiethylene)Bis-, Polymer With 1-Chloro-2,3-Epoxypropane is a high-performance polymeric amide-epoxy adduct, also known as a polyamide-epichlorohydrin resin. This compound is engineered to provide exceptional functionality as a wet-strength additive and cationic retention aid in paper manufacturing. It is a critical material for producers seeking to enhance the durability and performance of paper and board products under wet conditions. The product is supplied under CAS No. 26062-92-0.

Application

• Wet-Strength Resin for Paper & Board: Primary application as a cationic polymer to significantly improve the tensile strength of paper products when wet, used in tissue, towel, filter media, and packaging grades.
• Retention and Drainage Aid: Functions in papermaking systems to improve the retention of fine particles and fillers, enhancing sheet formation and increasing drainage rates on the wire.
• Surface Sizing Agent: Used to modify surface properties, improving printability, ink holdout, and reducing porosity of paper and paperboard.
• Flocculant for Water Treatment: Applied in industrial water clarification processes due to its cationic charge and polymeric structure, effective for solids removal and sludge dewatering.
• Additive for Specialty Coatings: Imparts improved adhesion, water resistance, and mechanical properties in certain coating and adhesive formulations.

Quality Control

Our polyamide-epichlorohydrin resin is manufactured under strict process controls to ensure batch-to-batch consistency and performance reliability. Quality is verified through a comprehensive suite of analytical tests including solids content, viscosity, charge density, and active matter determination. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at ambient temperatures (15-25°C). Avoid freezing and prolonged exposure to elevated temperatures. Keep away from strong oxidizing agents. The shelf life is typically 6-12 months from the date of manufacture when stored under recommended conditions.
