Silductor 6350 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. Silductor 6350 is printable and dispensable.
- Special Features & Benefits

- Processing Instruction
- Important! Silductor 6350 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 Silductor 6350 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 United Adhesives, Inc.

General hygiene regulations should be observed.
Storage & Handling
- Shelf Life
- 6 months at 40°C (ITM)
- Storage
Silductor 6350 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.
