m-Xylylenediamine is an industrial chemical.
Uses
m-Xylylenediamine (MXDA) is used in a variety of industrial applications. It finds use in amine based curing agents for epoxy resins [4]. These may then be formulated into paints, sealants, adhesives, and coatings.[1]
Hazards
Exposure to m-xylylenediamine may occur via inhalation, skin contact, eye exposure, or ingestion. It can cause chemical burns, tissue damage, delayed pulmonary edema, shock, and skin sensitization. Symptoms of inhalation include a burning sensation in the respiratory tract, cough, sore throat, labored breathing, and dyspnea(shortness of breath). It is also flammable and produces toxic fumes when burned. m-Xylylenediamine reacts with acids, acid chlorides, and acid anhydrides.[1][5]
