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.
Reduces assembly delays caused by incomplete curing in concealed joints. Eliminates the need for multiple adhesives to handle varied substrates. Improves manufacturing efficiency with rapid cure and tack free finish. Provides a compliant bonding solution for regulated industries such as medical devices.
LOCTITE® 4305 LC is used for bonding plastics, metals, rubbers, and ceramics in industries where speed and compliance are essential. Apply to clean, dry surfaces, cure exposed areas with UV light, and allow ambient moisture to complete curing in concealed joints. Ideal for medical device assembly, precision electronics, and small component manufacturing where appearance, performance, and safety are critical.
