Our Business

Functional Materials Business

In our functional materials business, we provide materials with various functions, such as epoxy resins that serve as an insulating material for semiconductor encapsulation, UV-curable resins used in various fields such as color resists, solder masks and hard coatings, and maleimide resins, with high heat resistance and low transmission loss, used in circuit boards for “5G” next generation mobile communication systems.

In addition, we also develop high value added products for use in a wide range of fields. These products include formulated resin composites such as Sealants for LCD, Sealants for LED, Photoresists and Insulating materials for micro electro mechanical systems (MEMS) that combine our proprietary resins with structuring technologies, various optical films for light control and management. In addition, we also offer a line-up of cleaning agents and chemicals (developing solutions, bulk removers and residue removers) used for producing LCD panels (color filters) and semiconductors.

Main Products

Environmentally Friendly Epoxy Resins


NC-3000 series that Nippon Kayaku developed as an environmentally friendly epoxy resin does not only remain as a semiconductor encapsulation, but its unique properties in print circuit boards, in composites, and in other areas have been recognized. As a result, it is becoming the de facto standard as a high-end product in the market.

For the black portion, epoxy resins are used which are the insulating material for semiconductor encapsulation.
Nippon Kayaku's epoxy resins are used in familiar places such as automobiles, TVs, PCs, and mobile phones.


We engage in the development, manufacture and marketing of chemicals used in each manufacturing process for high resolution and high performance displays, semiconductors and electronic components markets. Harnessing our capabilities in proprietary development, we have established a product lineup with excellent performance that is unrivaled by peers. This product lineup contributes to the development of the entire electronics industry.
