4,4'-Methylene bis(2-chloroaniline),CAS: 101-14-4, is a solid substance, usually in the form of crystals or powder. It has certain solubility characteristics in some organic solvents, but is relatively insoluble in water. As an important curing agent for epoxy resin, it can react with epoxy groups to form cross-linked structures, thereby enhancing the mechanical properties, heat resistance and chemical resistance of epoxy resin-based materials. This makes it widely used in the production of coatings, adhesives and composite materials. For instance, in the coating of metal surfaces, it can enhance the adhesion and durability of the coating.
