m-Xylylenediamine (MXDA) Curing Agent
CAS Number: 1477-55-0
m-Xylylenediamine (MXDA) is a primary aliphatic/araliphatic diamine curing agent for epoxy resins, offering faster room-temperature cure and higher chemical resistance than purely aliphatic amines. Its benzylic amine structure provides high reactivity, allowing thin-film cure at low temperatures and excellent adhesion to steel and concrete. MXDA is widely employed in corrosion-protective epoxy coatings, marine adhesives, and low-temperature-cure civil engineering grouts.
