Epoxide monomers are oxirane compounds with polymerizable functional groups and are important raw materials for epoxy resins.¹⁾ Epoxide resins are one of thermosetting resins, which are used in adhesives, paints, inks, and sealants, as well as in electronic materials such as printed circuit boards (PCBs), encapsulants, and display materials.²⁾ They are also used as matrix resins for composite materials, such as carbon fiber-reinforced plastics (CFRP), and their importance has been increasing in recent years. In addition, since epoxy monomers cure through ring-opening polymerization, they exhibit low polymerization shrinkage, and active research has been conducted on their application in dental materials, where high dimensional stability is required.³⁾

In recent years, the development of ultra-high-speed communication technologies compatible with 5G and 6G has increased the demand for low-dielectric-constant materials that minimize signal loss and delay.⁴⁾ In addition, to achieve further miniaturization of electronic devices, higher circuit integration density and improved heat resistance to withstand thermal stress are required. There is also a growing need for low-chlorine materials to prevent circuit corrosion,⁵⁾ as well as for bio-based monomers and their raw materials to contribute to a sustainable society and the realization of the SDGs.⁶⁾

For epoxide resins, not only heat resistance and mechanical strength but also various other properties such as transparency, curing speed, water resistance, weather resistance, low viscosity, and flame retardancy need to be improved depending on the application. To address these challenges, epoxy monomers with diverse molecular backbones are required.

To meet the growing needs in epoxide resin development, we are actively expanding its lineup of epoxide monomers. Currently, more than 90 products are available, including those with distinctive features such as alicyclic structures, rigid polycyclic aromatic backbones, fluorine-containing compounds, and hydrophilic monomers incorporating PEG. In addition, We offer a wide range of reagents essential for epoxide resin production, such as curing agents (amines, thiols, and acid anhydrides) and photo and thermal cationic polymerization initiators. are also available.
