①Biodegradable, water-soluble resin

Nichigo G-Polymer™ is a new vinyl alcohol resin that is unparalleled throughout the world (butandiol vinyl alcohol co-polymer resin [BVOH]). The resin can be used to freely control crystallinity and the cohesive power of the non-crystalline part. It is being increasingly used in various applications as an environmentally friendly water soluble resin that achieves high gas barrier performance, formability, and biodegradability in addition to outstanding transparency and solvent resistance.

②Polyvinyl alcohol compatible with pharmaceutical additive  

The GOHSENOL™ EG-P series is a purified polyvinyl alcohol. It can be used for binders, coating agents, thickeners (for ophthalmic/nasal solutions), gel patches, emulsifiers, OD film substrates, etc. We have continued to develop various applications.

③High performance adhesive

COPONYL™ is a copolymer resin made mainly from acrylic acid ester. We succeeded in developing an adhesive for pasting polarizing plates that is characterized by excellent optical properties and durability. We also market proprietary highly functional adhesive through integration with UV technologies for the SHIKOH™ UV curable resin.
