LOCTITE® 4304 LC is a one component, medical grade cyanoacrylate adhesive that delivers rapid UV cure and moisture cure in shadowed areas. It bonds well to plastics, rubbers, metals, ceramics, and paper, and becomes tack free within five seconds. It is also ISO 10993 biocompatible.
LOCTITE® 4304 LC is designed for fast and reliable bonding in industries that require clean and precise adhesion. Its low viscosity ensures smooth application on rigid or opaque substrates, while the dual cure system of UV for surface cure and moisture for concealed areas ensures complete bonding even in shadowed joints. With a tack free finish in approximately five seconds, it enhances productivity by accelerating assembly time. The medical grade certification ISO 10993 makes it particularly suitable for medical device assembly, diagnostic equipment, and other hygienic or clinical applications without compromising bond strength or clarity.

Eliminates incomplete curing in hard to access areas. Minimises downtime with fast handling strength. Supports use across diverse substrates without the need for multiple adhesives. Enables clean and compliant bonding in medical or hygienic environments.
LOCTITE® 4304 LC is ideal for precise bonding of plastic, metal, rubber, ceramic, or paper components, especially in medical device assembly. Apply a thin layer, expose directly to UV light for surface cure, and allow ambient humidity to complete bonding in shaded areas. As a single component adhesive, it simplifies workflow and improves throughput without compromising bond integrity or clarity.
