Sarcon® SPG-20B is highly conformable/thermally conductive, low viscosity and easier dispensable type silicone compound. It provides a thermal solution for the recent trends of higher frequencies and integration in the development of electronic devices. Sarcon® SPG-20B easily forms and adheres to most of surfaces, shapes, and sizes of components.

Sarcon® SPG-20B makes complete and reliable physical contact with the component and opposing surfaces. It provides handling properties that are superior to thermal grease & potting materials.

FEATURES:

  • Suitable for filling the delicate gaps and still provide superior thermal transfer.
  • Highly conformable with very low compression forces.
  • Has excellent vibration absorption capabilities.
  • Maintains thermal properties across a wide temperature range.
  • Can be used to "Form-In-Place" and will remain form stable.
  • Requires no heat curing.
  • Will not cause corrosion on any metal surface.
