CHO-THERM® 1641 and 1642 Compounds


CHO-THERM® thermally conductive silicone compounds are flexible, low modulus systems ideal for heat transfer applications in electronic component cooling.

CHO-THERM 1641 one-part compound is formulated for sensitive electronic components in power supplies, medical instruments and motion control applications.


CHO-THERM 1642 two-part adhesive/sealant/caulk/ potting compound provides higher thermal conductivity than 1641 material. It is formulated for thick applications and low humidity conditions.


These CHO-THERM compounds will stick, but not permanently bond to most non-silicone surfaces. Permanent bonds can be made using a Chomerics CHO-BOND conductive primer.
