TOKYO -- February 6, 2014

Mitsui Chemicals (TOKYO:4183)(President & CEO: Toshikazu Tanaka) announced
that the Company will take its competitive edge in its world top share
ophthalmic lens monomers and coatings & engineering materials to the next
level by constructing the world’s first large scale plant for XDI within its
Omuta Works (Kyushu, Japan). This new development is one of several measures

1. Product: XDI (xylylene diisocyanate)
2. Location: Omuta Works (Omuta City, Fukuoka Prefecture, Japan)
3. Capacity: 5,000 tons/year
4. Commercial operation: October 2015 (tentative)

XDI is a functional material made with proprietary technology and offered only
by the Mitsui Chemicals Group. Extensively used in coatings & engineering
materials, it is widely used in products requiring safety and durability such
as adhesives for food packaging, in special inks and coating materials such as
those used in solar cells and smartphones, and in high durability building
sealants and highly safe microcapsules. Additional demand is also expected by
product shifts from different materials.

XDI is also used in the Group’s world leading high refractive index ophthalmic
lens monomers, sold under the brand name MR^TM Lens, which allow processing
and design freedom, and have superior durability, clarity, impact resistance,
and thinness. Mitsui Chemicals revolutionized the global standard for eyewear
with its “thin, light, and impact resistant lens material”.

“The new state-of-the-art XDI plant will not only enable Mitsui Chemicals to
meet expanding demands for specialty coatings & engineering materials, but
will also provide solutions to QOL needs for improved and more comfortable
eyewear around the world,” says Satoshi Tsuruda, General Manager of Health
Care Materials Division at Mitsui Chemicals.

With the establishment of its new XDI plant, Mitsui Chemicals will
aggressively expand its global business and strengthen its world class
competitive position for its ophthalmic lens monomers operations and coatings
& engineering materials operations.
