The Multhiol® series is a family of ether-type polyfunctional thiols, consisting of Multhiol® Y-3 (trifunctional) and Multhiol® Y-4 (tetrafunctional) grades. While retaining the key advantages of the conventional ester-type polyfunctional thiols TMMP and PEMP, including rapid curing, low-temperature curing, improved adhesion, and UV sensitization, the ether structure provides enhanced flexibility and water resistance. The series can be used as UV-curing sensitizers, epoxy curing agents, and additives for dual-curing systems, making it suitable for high-reliability applications such as electronic adhesives and encapsulation materials.

This dispersion contains zirconium oxide nanoparticles with a particle size of less than 10 nm, stably dispersed at a high concentration. When incorporated into resins, it enables a higher refractive index while maintaining excellent transparency by leveraging the unique properties of nanoparticles. It is well suited for applications requiring superior optical performance, such as optical components, hard-coat materials, and advanced coating materials.
