Appearance of m-Xylylenediamine
m-Xylylenediamine (MXDA) is a colorless liquid with a characteristic almond-like odor. Upon prolonged exposure to air, it gradually turns yellow. Its viscosity is comparable to that of dibutyl phthalate, and it is soluble in both water and organic solvents.
Properties and Applications of MXDA
As an epoxy resin curing agent, MXDA is an aliphatic amine containing a benzene ring. It features low viscosity and enables curing at room temperature. The presence of the benzene ring in its molecular structure imparts superior heat resistance to the cured product compared with vinylamine. Additionally, MXDA provides excellent resistance to water, acids, alkalis, and a wide range of chemicals, making it widely applicable in casting, adhesives, and anti-corrosion coatings.

m-Xylylenediamine (MXDA) is mainly used in the production of epoxy resin curing agents, photosensitive plastics, rubber additives, polyurethane materials, and coatings. As a curing agent, it serves as a raw material for polyurethane resins and modified epoxy resins. In addition, MXDA is applied in the manufacture of rubber additives, photosensitive plastics, pesticides, coatings, nylon products, textile finishing agents, corrosion inhibitors, chelating agents, lubricants, and paper processing. It also finds applications in several other fields.
The unique molecular structure of MXDA gives it excellent physical and chemical properties, enabling wide applications. Both MXDA and its cyclic hydrides are highly effective as epoxy resin curing agents, offering low viscosity, ease of handling, excellent room-temperature curing, as well as strong heat, water, and chemical resistance. They also provide smooth and transparent cured resin surfaces. Furthermore, MXDA is an important intermediate in fine chemicals. It can be used to synthesize polyamides with dibasic acids, or to prepare m-xylene diisocyanate, a key monomer for polyurethane. Its benzene ring hydride derivatives can also be employed in diisocyanate synthesis. Currently, MXDA is utilized in the development of rubber crosslinking agents, pesticides, fiber stabilizers, surfactants, and other specialty chemicals.
