DOWSIL SC102

Main features

  • Moderate Thermal-Conductivity Compound
  • One-Part Non-Curing Processing
  • Critical-Component Heat Transfer

Product Description

DOWSIL™ SC 102 Compound is a one-part, white, non-curing, non-flowing thermally conductive silicone compound formulated with heat-conductive fillers to improve heat transfer between electronic components and heat sinks. Designed for thermal management in PCB system assembly modules, the compound helps dissipate heat from critical components in computer, power supply, and automotive applications. Its combination of moderate thermal conductivity, low bleed characteristics, high non-volatile content, and electrical insulation properties supports reliable thermal interface performance while simplifying application and rework processes.

Key features

  • One-part formulation: Ready to use without mixing, ovens, or curing processes.
  • 0.9 W/m·K thermal conductivity: Supports efficient heat transfer away from temperature-sensitive electronic components.
  • Low bleed performance: A typical bleed value of 0.14% helps maintain interface stability during operation.

Applications / Suitable for

  • PCB system assembly modules
  • Computer electronics
  • Power supply assemblies
  • Automotive electronic systems
  • Heat sink-to-component thermal interfaces

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

measures how well the thickener matrix (the "sponge") retains the base oil under static conditions when exposed to heat over time.

Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application

Thermal Properties
Thermal Conductivity
Thermal conductivity describes the ability of a material to conduct heat. It is required by power packages in order to dissipate heat and maintain stable electrical performance. Thermal conductivity units are [W/(m K)] in the SI system and [Btu/(hr ft °F)] in the Imperial system.

Electrical Properties
Dielectric Strength
Dielectric strength is measured in kV per mm and is calculated by the Breakdown voltage divided by the thickness of the tested material. Those two properties go hand in hand and while Breakdown voltage is always thickness dependent, dielectric strength is a general material property. As an example, the dielectric strength of Polyimide is 236 kV/mm. If we place 1mm of Polyimide between two electrodes, it will act as an insulator until the voltage between the electrodes reaches 236 kV. At this point it will start acting as a good conductor, causing sparks, potential punctures and current flow.
2 kV/mm
Volume Resistivity
Volume resistivity, also called volume resistance, bulk resistance or bulk resistivity is a thickness dependent measurement of the resistivity of a material perpendicular to the plane of the surface.
