Product Description
LOCTITE® ABLESTIK FDA 2 BIPAX is a two-part, electrically insulating epoxy adhesive for medical-device bonding applications. Formerly known as TRA-BOND FDA2, the amber, medium-viscosity system mixes at 100:100 by weight and provides a typical pot life of 45 minutes and work life of 3 hours. It can be cured for 24 hours at 25°C or accelerated for 1 to 4 hours at 65°C. The cured adhesive has a documented operating-temperature range of -70 to 145°C, typical volume resistivity of 1.20 × 1014 ohm-cm at 25°C, and aluminum-to-aluminum lap shear strength of 1,800 psi.
Key features
- Electrically insulating: Typical cured properties include volume resistivity of 1.20 × 1014 ohm-cm at 25°C and dielectric strength of 420 V/mil.
- Medium-viscosity processing: Typical mixed viscosity of 14,000 mPa·s at 25°C supports controlled adhesive application.
- Room-temperature or heat cure: Guideline schedules include 24 hours at 25°C or 1 to 4 hours at 65°C.
Applications / Suitable for
- Catheters
- Hearing aids
- Dental products
- Other biomedical instruments and devices
