2 Polycarbonatediol(PCD) is a linear polycarbonate with hydroxyl groups at both ends. It easily reacts with isocyanate compounds (e.g. MDI, TDI, IPDI, H 12 MDI) and generates polymers with superior characteristics described below. The proprietary manufacturing technology of Mitsubishi Chemical Corporation (MCC) enables production of unique composition and higher molecular weight PCDs with stable product qualities. The resins made from MCCʼs PCDs BENEBiOL TM have unique properties that existing resins have not been able to establish. In addition, some of the PCDsʼ raw materials are biomass-based.

7 MCCʼs PCDs BENEBiOL TM have superior characteristics for use in the soft segment of polyurethane, acrylic resins and polyester resins. The polymer obtained is durable, for use in a wide range of applications such as furniture, automobile interiors, automobile paints, plastic coatings for electronics, adhesives, films, seats and ordinary consumables and various industrial materials. Its applications are expected to increase in the future. Polyurethane applications Artificial leather / synthetic leather Paint and coating materials Waterborne urethane Polyurethane elastomers Thermoset elastomer (TSU) Thermoplastic elastomer (TPU) Adhesives / sealants Acrylic resin applications Urethane acrylated compounds and resins Diacrylated compounds and resins Polyester applications Polyester elastomers (TPEE) REVISION DATE Apr. 1, 2018 Page 7 of 8

8 BENEBiOL TM should be sealed in a container with dry nitrogen since it is moderately hygroscopic. NLDB and NLB (Crystalline) grades are at room temperature, and it can become a colorless transparent when heated. Before using BENEBiOL TM, to melt BENEBiOL TM in a drum, it should be heated at temperature above its melting point. Under transport regulations, BENEBiOL TM is not classified as UN hazard class. BENEBiOL TM has low volatility and will not spontaneously ignite at room temperature. In the event of fire, dry chemicals foam and plenty of water spray are effective for extinguishing. Safety glasses and protective gloves should be worn when handling BENEBiOL TM. For further details, please refer to Safety Data Sheets issued by Mitsubishi Chemical Corporation. BENEBiOL TM are produced for industrial applications. If the intended use for BENEBiOL TM is for body contact applications such as pharmaceuticals, foods, cosmetics, please contact MCC in advance.
