NINGBO INNO PHARMCHEM CO.,LTD. is dedicated to supplying high-quality fine chemicals that serve as the backbone for numerous industrial innovations. One such crucial fine chemical is 4,4'-Methylene-Bis(3-Chloro-2,6-Diethylaniline), commonly referred to as MCDEA. Understanding its chemical properties is key to appreciating its broad industrial significance.

MCDEA is an aromatic diamine derivative with the molecular formula C21H28Cl2N2 and a molecular weight of 379.37. Typically appearing as off-white granules, it possesses properties that make it highly valuable in polymer chemistry. Its primary function is as a curing agent and chain extender, particularly for polyurethane and epoxy resin systems. The presence of chlorine atoms and diethyl groups on the aniline rings contributes to its unique reactivity and performance characteristics.

In polyurethane applications, MCDEA reacts with isocyanate prepolymers to form robust polymer chains. This process leads to enhanced physical and dynamic mechanical properties in the resultant elastomers, including improved heat resistance and durability. Its role in polyurethane casting, spraying, and RIM processes highlights its versatility in manufacturing diverse products like microcellular foams and thermoplastic polyurethanes (TPU).

As a curing agent for epoxy resins, MCDEA acts as a hardener, facilitating cross-linking reactions that result in strong, chemically resistant materials. This makes it suitable for high-performance adhesives, coatings, and composite materials. The chemical's generally low toxicity, particularly compared to some other aromatic amines, is a significant advantage, contributing to safer handling and processing in industrial settings.
