ARATHANE® 7762-1

ARATHANE® 7762-1 Adhesive is a mercury-free, single-component polyurethane specifically formulated as a thermal transfer adhesive (TTA). It is designed to have high purity and very low outgassing characteristics. It features extremely good thermal shock resistance combined with excellent hydrolytic stability and resistance to solder processing temperatures and most common printed wiring board cleaning chemicals. ARATHANE® 7762-1 Adhesive can be automatically dispensed for high-output applications and reduced handling. This adhesive is a variant of the ARATHANE® 7760-1 product, designed to provide a controlled bond line thickness (5 mil). It is ideally suited for bonding “flat packs,” PLCCs, and other devices where control of bond line thickness is critical or desired. 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® 7762-1 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 it to equilibrate at room temperature (30°C maximum) only.
  • Do not attempt to quick thaw by heating, as this will greatly reduce working life.
  • Typical thawing time for 10cc syringe is 15 minutes at 25°C.

Storage & Handling

Storage Information
  • Arathane® 7762-1 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 shelf life is 3 months (from date of manufacture).
  • The product should not be exposed to direct sunlight. For shipment this product is packaged in special Styrofoam cartons containing enough dry ice for a limited storage life of approximately 96 hours during shipment.
  • Upon receipt, frozen syringes must be transferred to freezer storage at temperatures below <-40°C (<-40°F) to ensure product shelf life reliability.
  • Special care should be taken when handling dry ice to avoid severe skin damage or potential of asphyxiation in unventilated areas.
