LOCTITE® AA 3971: Fast-Curing Medical-Grade Adhesive for Plasticized Materials
LOCTITE® AA 3971 is a low-viscosity, UV-curable acrylic adhesive designed for rapid bonding in medical device assembly, particularly those involving plasticized materials.
Key Features:
- Fast Cure: Achieves strong bonds in seconds upon exposure to UV light, ideal for high-volume production.
- High Adhesion to Plasticized Materials: Bonds effectively to materials commonly used in medical devices.
- Medical-Grade: Meets ISO-10993 biocompatibility standards for safe use in medical applications.
- Low Viscosity: Well-suited for post-assembly dispensing, filling gaps between cannulae and hubs in syringes and lancets.
- UV Fluorescence: Enables easy quality inspection under UV light for verifying proper adhesive presence.
- Specifically Designed for Medical Devices: Ideal for bonding stainless steel cannulae into hubs, syringes, and lancets.
Applications:
- Assembly of disposable medical devices, particularly those involving plasticized materials.
- Bonding cannulae into hubs, syringes, and lancets.
