Thermosetting resins such as epoxy resins are commonly used for adhesives and sealants in electrical and electronic applications, but the majority of these cure through heat, which limits the range of applications. In addition to thermal curing reactions, epoxy resins have long been polymerized through cationic UV curing. Recently, with the development of excellent photobase generators, anionic UV curing and frontal UV curing have also been put into practical use. Furthermore, oxetanes can be synthesized through ring-opening polymerization caused by acids generated during cationic UV curing. Cationic/anionic/frontal polymerization offers faster curing compared to thermosetting and achieves comparable physical properties. Additionally, it has advantages such as being unaffected by oxygen inhibition like radical polymerization and having a low shrinkage rate. It is also possible to cure deep within thick films.

• Composite Materials

Features: - Various functional fillers are uniformly dispersed in a liquid diol/polyol medium, and stability over time is also good. - By using a dispersion of various functional fillers in a liquid diol/polyol medium for reactions (curing) with isocyanates, it becomes possible to design various solvent-free functional materials.

• Composite Materials

Spherical silica is often used as a filler to protect electronic materials, particularly semiconductors, and by using special spherical silica, we are able to implement "low dielectric constant." Additionally, boron nitride is well-known for its excellent thermal conductivity, but it also possesses excellent insulation and low dielectric constant. Since hexagonal boron nitride is in the form of spherical nanoparticles rather than flakes, it is expected to provide heat dissipation without the need for controlling anisotropy, in addition to having a low dielectric constant. Customization is available according to your needs (such as improving compatibility with target materials or changing solvents).

• Composite Materials

It is considered that "low dielectric constant" is an effective factor in achieving "low latency" in next-generation communication systems. Features: - The black nanoparticles are uniformly dispersed, resulting in good coloration and excellent long-term stability. - They have a significant advantage in terms of low dielectric constant compared to conventional black nanoparticles (carbon black) (they can maintain a low dielectric constant). - We are designing for dispersion (and compatibility design) using NMP/DMAc as the main solvent, with the intention of imparting color (black) to low dielectric materials such as polyimide (PI) and liquid crystal polymer (LCP), as well as for circuit concealment. - Please consult us for customization options such as solvent changes to cyclohexanone (anon)/MEK/toluene for low dielectric materials like epoxy/bismaleimide/cycloolefin polymer (COP)/polyphenylene ether (PPE), as well as improvements in compatibility.
