Description

Poly(m-Xylylenediamine-Alt-Epichlorohydrin), Diamine Terminated is a specialized, functionalized polyamine resin derived from the alternating copolymerization of m-xylylenediamine and epichlorohydrin. This engineered polymer is valued for its terminal primary amine groups, which provide high reactivity for cross-linking and modification in advanced material synthesis. It serves as a critical building block for manufacturers in the coatings, adhesives, and composite industries seeking to enhance the mechanical and thermal properties of their final products.

Application

• Epoxy Curing Agent & Hardener: Functions as a reactive diamine curing agent for epoxy resins, contributing to improved toughness, chemical resistance, and thermal stability in high-performance coatings and composites.
• Polyamide & Polyimide Synthesis: Serves as a key monomer or chain extender in the production of specialty polyamides and polyimides for fibers, films, and engineering plastics.
• Water Treatment Resins: Used in the formulation of ion-exchange resins and flocculants for industrial water purification and wastewater treatment processes.
• Adhesive & Sealant Formulations: Imparts enhanced adhesion and flexibility as a modifier in structural adhesives, sealants, and potting compounds.
• Paper & Textile Chemical Additive: Acts as a wet-strength resin and retention aid in paper manufacturing, and as a finishing agent for textiles.
• Pharmaceutical & Cosmetic Intermediate: Employed in the synthesis of specialized polymers for controlled drug delivery systems and cosmetic film formers.

Quality Control

Our production of Poly(m-Xylylenediamine-Alt-Epichlorohydrin), Diamine Terminated adheres to stringent quality management protocols. Each batch undergoes rigorous analytical testing to ensure consistent properties such as amine value, equivalent weight, viscosity, and residual monomer content. Certificates of Analysis (COA) documenting these specifications are provided to guarantee compliance with your technical requirements and support your own quality assurance processes.

Storage

Preserve in a tightly closed container, protected from light. This material is hygroscopic (moisture-sensitive) and must be stored in a cool, dry place at room temperature (15-25°C/59-77°F) under an inert atmosphere (e.g., nitrogen) to prevent moisture absorption and potential degradation. Keep away from heat and incompatible materials such as strong acids and oxidizing agents.
