Main features
- Flexible Cured Adhesive
- 0.9 W/(m K) Thermal Conductivity
- Reworkable Bonding Material
Product Description
LOCTITE® ABLESTIK 506 is a slightly tacky, flexible epoxy adhesive film designed for bonding materials with severely mismatched coefficients of thermal expansion. The white, glass-fabric-supported film has a documented thickness of 3 mil and is suitable for assembly bonding of plastics, ceramics, and difficult-to-bond metals. Its tack can support component positioning without holding fixtures for approximately 16 hours after removal from frozen storage. Guideline heat-cure schedules include 60 minutes at 150°C, 90 minutes at 125°C, or 3 hours at 100°C.
Key features
- Flexible adhesive film: Designed for bonding adherends with severely mismatched coefficients of thermal expansion.
- Thermally conductive and electrically insulating: Typical cured properties include thermal conductivity of 0.9 W/(m·K) at 121°C and volume resistivity of 0.7 × 1013 ohm-cm.
- Reworkable, tacky construction: Slight tack supports component positioning, while the documented rework procedure uses heating to 125°C followed by mechanical separation.
Applications / Suitable for
- Assembly bonding of materials with severely mismatched coefficients of thermal expansion
- Bonding plastics and ceramics
- Bonding difficult-to-bond metals
- Applications requiring a flexible, reworkable adhesive film
