Characteristics
USG646 is a Silver-Copper filled electrically conductive silicone adhesive designed for electronic applications. After cure at elevated temperature, it forms a flexible, rubbery conductive adhesive having electrical and thermal conductivity with strong bonding to various metals surfaces. It is used for low stress soldering, connecting, conducting, and grounding applications. USG646 is printable and dispensable.
Special Features and Benefits
• Flexible for low stress bonding
• Good electrically conductivity
• High thermal conductivity
• High temperature stability
• Strong bonding to various surfaces
• Low bleeding, low volatile
• Low ionic content
• Reworkable
Typical Applications
• Aerospace and Automotive electronics
• Semiconductor and Telecommunications
• Conducting while dissipating heat
• Grounding of power devices
• EMI shielding and gasketing
• Thermally conductive bonding
USG646 has a shelf life of at least 6 months when stored at < - 15°C in the originally sealed container.

Processing Instruction
Important! USG646 is platinum cure system. Please keep applied surface clean and avoid using this material on any surface that contains sulfur, amine, phosphorous, organo-metals, acid, etc., because these contaminants could inhibit the cure of the material.
Always store unused USG646 in freezer (< -15 °C) to prevent any possible deteriorating of the material.
We recommend running preliminary tests to optimize conditions for the particular application. Comprehensive processing instructions can be obtained by contacting directly to USGlue.com.
Storage
USG646 has a shelf life of at least 6 months when stored below - 15 °C in the originally sealed container. The 'Best use before end' date of each batch appears on the product label. Storage beyond the date specified on the label does not necessarily mean that the product is no longer usable. In this case however, the properties required for the intended use must be checked for quality assurance reasons.
Safety information
General hygiene regulations should be observed. Comprehensive instructions are given in the corresponding Material Safety Data Sheets. They are available on request from USGlue.com.
