METADUCT 1216-2 ELECTRICALLY CONDUCTIVE SILVER EPOXY ADHESIVE

ONE-PART ELECTRICALLY CONDUCTIVE SILVER-FILLED EPOXY ADHESIVE AND SEALANT

PROTAVIC Metaduct 1216-2 is a new, electrically conductive silver-filled epoxy adhesive that has been developed specifically for connector and interconnect bonding applications where an electrically conductive adhesive system with good bond strength to a variety of substrates is required. Metaduct 1216-2 Series has also been used extensively in electrical termination bonding, and bonding electronic components to circuit boards and leadframes.

This product is also available in a lower viscosity version (Metaduct 1216-2LV) with a slight decrease in electrical conductivity (0.005 ohm-cm).

No Mixing, Easy Cure Schedule
Metaduct 1216-2 can be cured in 2 hours at 125° C. To attain maximum properties, a post cure of 1 hour at 150° C is recommended.

Air Removal
Air entrapment may be removed in vacuum (5mm of mercury). The holding container should be no more than one-third full. Allow the mixture to foam and then subside. Maintain the low pressure for several more minutes, until most of the large bubbles have broken.

Application
The adhesive should be applied in a 2-5 mil thickness to one surface after which the parts are mated and set aside to cure using the recommended cure schedules.

Safety, Storage, and Handling
Before using Metaduct 1216-2, consult the Material Safety Data Sheet for appropriate handling procedures and protective equipment.
