Description

m-(2,3-Epoxypropoxy)-N,n-Bis(2,3-Epoxypropyl)Aniline is a high-purity, multi-functional epoxy resin intermediate. This compound is valued for its trifunctional nature, providing three reactive epoxy groups that enable the formation of highly cross-linked, durable polymer networks. It is essential for manufacturers in the advanced composites, high-performance adhesives, and specialty coatings industries seeking to enhance thermal stability and mechanical strength in their formulations.

Application

• Advanced Composite Materials: A key cross-linking agent for aerospace and automotive composites requiring high strength-to-weight ratios and thermal resistance.
• High-Performance Adhesives & Sealants: Used to formulate structural adhesives with superior chemical resistance and bond strength for demanding industrial applications.
• Specialty Epoxy Coatings: Serves as a critical building block for industrial, marine, and protective coatings that must withstand harsh environments.
• Electrical Encapsulation & Potting: Employed in the production of insulating materials for electronic components due to its excellent dielectric properties and low shrinkage upon curing.
• Fiber-Reinforced Polymers (FRP): Acts as a matrix resin modifier to improve the interfacial adhesion between fibers and the polymer matrix.
• 3D Printing Resins: A valuable component in formulations for stereolithography (SLA) and other additive manufacturing processes requiring precise, durable outputs.

Quality Control

Our m-(2,3-Epoxypropoxy)-N,n-Bis(2,3-Epoxypropyl)Aniline is produced under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure high purity, consistent epoxy equivalent weight (EEW), and low hydrolyzable chloride content, which are critical for predictable curing performance. Certificates of Analysis (COA) detailing purity, viscosity, and other key parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can prematurely initiate polymerization and affect product performance.
