Product Overview

The CW7270 from Chemtronics is a CircuitWorks® silicone free heat sink grease. It facilitates heat transfer away from electrical/electronic components and into heat sinks. This silicone free compound shows no creep or migration over a wide temperature range. Thickened with a proprietary thermally conductive zinc oxide ceramic, the CircuitWorks® silicone free heat sink grease creates an effective heat sink interface in electrical/electronic equipment. It also provides excellent heat transfer between circuit components and heat sinks without any silicone migration. CircuitWorks® silicone free heat sink grease can be used for electronics applications including effective thermal coupler for any heat sink device, non-flammable protective coating, high voltage corona protection and it is excellent for improving readings on contact type thermocouples. It is ideal for silicone sensitive environments and it is generally compatible with most materials used in printed circuit board fabrication.
