- Product Applications
- This tough adhesive has an excellent combination of shear and peel strength.
- It has also excellent impact and vibration resistance and low temperature flexibility.
- This high-performance epoxy adhesive passes 500 thermal cycles from -50°C to 200°C.
- Semiconductor: capillary flow underfill for flip chip mounted die and glob top fill encapsulant.
- Electronics: heat sinking; thermally conductive potting and general protection of PCB and SMDs; potting and protection of resistor coils or Peltier devices.
- Instruction for Use
- Weigh each 100 grams of PART-A to 100 grams of Hardener PART-B.
- Mix until uniform. Scrape the sides and bottom of container repeatedly during mixing.
- Apply to clean bonding surfaces and cure as recommended to achieve the desired properties.
- Typical cured properties were determined using recommended cure schedule.
- Some difference in properties may occur with the alternate or other cure schedules.
- Industrial Usage
Practices of good housekeeping, safety and cleanliness should be followed before, during and after use.
