LOCTITE® 4305 LC is a one component, medical grade cyanoacrylate adhesive that combines UV light cure for rapid surface setting with moisture cure for shadowed areas. It bonds effectively to plastics, rubbers, metals, and ceramics, offering a tack free finish in just five seconds. ISO 10993 certification ensures it meets medical device biocompatibility requirements.
LOCTITE® 4305 LC is designed for demanding assembly applications where speed, reliability, and precision are essential. Its low to medium viscosity enables controlled application on rigid and flexible substrates, while the dual cure system guarantees full curing even in areas not directly exposed to light. With a tack free surface in approximately five seconds, this adhesive shortens production cycles and reduces handling time. The combination of strong substrate compatibility and ISO 10993 biocompatibility makes it particularly well suited for the assembly of medical devices, electronic components, and small precision parts requiring clean, high strength bonds.
