CircuitWorks Silver Conductive Grease (CW7100) – conductive grease
CircuitWorks Silver Conductive Grease (CW7100) from CHEMTRONICS is a 100% silver-filled conductive grease supplied in a 6.5 g (0.23 oz) syringe. The product is specified as a silver-gray, smooth paste with documented electrical and thermal properties.Technical description
The formulation is stated as 100% silver-filled grease and is designed to provide high electrical and thermal conductivity, as well as lubrication and protection against oxidation and moisture. The manufacturer's technical data indicates electrical resistivity, thermal conductivity, and temperature stability.
Typical applications
- Filling contact gaps to maximize electrical and thermal conductivity
- Grounding circuits
- Static discharge control
- Lubrication of contacts and slide rails (low to medium speed)
- Heat dissipation from transformers (stated by the manufacturer as an application)
- Extending the lifespan of rotating contacts and interchangeable contacts
Application notes
The manufacturer's documentation states that surfaces should be clean before application (e.g., with recommended cleaner). The product must not be diluted. A warning is given to disconnect power before application to avoid short circuits or sparking.
