ARATHANE® 7760-1

ARATHANE® 7760-1 Adhesive is a mercury-free, solvent-free, single-component material specifically formulated as a thermal transfer adhesive (TTA). It features excellent thermal shock resistance and is highly thixotropic with non-slump characteristics. This combination of physical properties improves process control capabilities. ARATHANE® 7760-1 Adhesive is easy to handle and is well suited for automatic dispensing used in high-output applications. It can be used for bonding, fileting, and protection of components on printed wiring boards or in other applications where high thermal expansion mismatches are problematic.

Technical Details & Test Data

Processing Information

Processing Data:

  • ARATHANE® 7760-1 Adhesive is frozen and packed in dry ice at the factory to minimize the possibility of exposure to high temperatures during shipment.
  • Avoid handling dry ice or frozen syringes with bare hands.
  • Remove syringe(s) from freezer storage and allow to thaw at room temperature (30°C/86°F maximum) only.
  • Do not attempt to quick thaw by heating, as this will greatly reduce working life.
  • Typical thawing time for syringes is 15 minutes at 25°C (77°F).

Storage & Handling

Storage Information
  • ARATHANE® 7760-1 Adhesive is considered non-hazardous for shipping purposes. However, this product is packaged in special Styrofoam cartons containing enough dry ice for a limited storage life of approximately 48 to 96 hours during shipment.
  • Upon receipt, frozen syringes must be transferred to freezer storage below -40°C to ensure product shelf life reliability.
  • Special care should be taken when handling dry ice in order to avoid severe skin damage or potential of asphyxiation in unventilated areas.
  • ARATHANE® 7760-1 Adhesive should be stored in a dry place, in the sealed original container, at temperatures below <-40°C (<-40°F). Under these storage conditions, the standard shelf life is 3 months (from date of shipment). The product should not be exposed to direct sunlight.
