- Dual-Cure Bonding Processing
- Low-Blooming Bonding Cure
Product Description
LOCTITE® 4314™ is a one-component, UV/light-curing ethyl cyanoacrylate adhesive formulated with a photoinitiator to provide rapid fixture speeds, surface cure capability and reliable bonding of plastics, rubbers and metals. The adhesive combines a primary UV/visible light cure mechanism with a secondary moisture-cure system, allowing cure in both exposed and shadowed bond areas. Its fluorescent appearance under UV light supports bond-line inspection and quality verification, while its low-blooming characteristics help maintain clean finished assemblies. The product is designed for high-speed industrial and medical-device assembly processes requiring fast curing and visual inspection capability.
