LOCTITE® 4311 LC is a one component, light cure cyanoacrylate adhesive that combines rapid UV surface curing with moisture curing for shadowed areas. It delivers high bond strength on plastics, rubbers, and metals while providing a tack free finish in just a few seconds. ISO 10993 certification ensures biocompatibility for use in medical device applications.
LOCTITE® 4311 LC is engineered for manufacturers who require precision, cleanliness, and speed in their bonding processes. The dual cure technology guarantees complete curing even in areas where light cannot penetrate, making it ideal for complex or opaque assemblies. Its low viscosity allows for precise dispensing and capillary action in tight fitting parts. With a tack free finish achievable in seconds, production throughput is improved and post curing steps are minimised. Biocompatibility testing to ISO 10993 makes it a safe choice for bonding components in medical devices, ensuring compliance without compromising performance.
