LOCTITE® AA 3974 Light Cure Adhesive
Features and Benefits
A 1-part, medium-viscosity, UV acrylic, light-cure adhesive for potting, sealing and bonding thermoplastics, glass and metals.
LOCTITE® AA 3974 is a translucent-colorless, medium-viscosity, UV acrylic-based, light-cure adhesive for potting, sealing and bonding thermoplastics, glass and metals. When exposed to sufficient UV and/or visible light, it cures rapidly to form a robust bond that stands up to heavy thermal cycling and harsh environmental conditions. This makes it highly relevant for use in the medical device industry to assemble disposable devices.
- Rapid curing
- ISO-10993 biocompatible for select medical devices
- Flexible
- Service/operating temperature: -54°C to 149°C (-65°F to 300°F)
