Mitsubishi Gas Chemical Halts Construction of 25,000 Tons Per Year MXDA Production Facility
Mitsubishi Gas Chemical Company, Inc. (MGC) announced that at the board meeting held on September 17, 2025, it was decided to suspend the construction of the m-xylene diamine (MXDA) production facility at its Dutch subsidiary, MGC Specialty Chemicals Netherlands B.V. (referred to as "MSCN"). The reasons for the suspension include construction delays, a significant increase in construction costs, and changes in the market environment.

MXDA (m-xylylenediamine) is reportedly a colorless liquid at room temperature and is an aliphatic diamine containing a benzene ring in its backbone. This unique chemical structure gives it distinctive properties when used in epoxy resins, polyamides, and polyurethanes.
① Meta-xylylenediamine (MXDA) possesses the characteristics of a room temperature curing agent and can be used as a high-end epoxy resin curing agent.
② Meta-xylylenediamine (MXDA) can be polymerized with adipic acid to synthesize a specialty nylon—MXD6. MXD6 possesses excellent gas barrier properties, high rigidity, high strength, high modulus, excellent heat resistance, low moisture absorption, dimensional stability, good processing performance, transparency, and chemical resistance. In terms of gas barrier properties, MXD6 is comparable to PVDC and EVOH, but the gas barrier property of MXD6 is not affected by temperature and humidity, making it particularly suitable for use in high-temperature and humid environments.
③ Meta-phenylene diamine (MXDA) can also be used to synthesize a special isocyanate called meta-phenylene diisocyanate (XDI). XDI possesses high strength, adhesion, flexibility, and durability. Its largest application area is in optical resins, mainly for the production of high-end optical lenses. Due to its excellent anti-yellowing properties and fast curing characteristics, XDI is also a key material for TPU-based films, coatings, and adhesives. It is widely used in the production of paint protection films, high-end coatings and inks, polyurethane adhesives for flexible packaging, and OCA optical adhesives.
As announced in MGC's press release on September 29, 2021, MGC has been constructing an MXDA production facility at MSCN in order to establish a new production base in Europe, the largest market for MXDA, and plans to start operations in July 2024.
During the project implementation, the following issues arose: the replacement of the contractor during the construction period led to delays, the Russia-Ukraine conflict caused a significant increase in construction and labor costs, and the MXDA market environment changed. These issues may result in the project's commercial viability being lower than initially planned. In view of the current situation, MGC has decided to suspend the construction work of MSCN and reassess the business plan (including whether to continue with the project).
