  • Low- and High-Voltage Encapsulation

Product Description

Circalok 6716 Silicone Resin is the resin component of a two-component, solvent-free RTV silicone system used with Circalok 6733 hardener. The black liquid has a typical viscosity of 10,000 cP and specific gravity of 1.40 at 25 deg C. When combined with Circalok 6733 hardener, the resin and hardener mix at 100:2.5 by weight, provide a typical 45-minute working life at 25 deg C, and cure in 12 to 16 hours at 25 deg C. The system is used for potting and encapsulating both low- and high-voltage electrical and electronic assemblies.

Key features

  • 6733 Hardener Pairing: Circalok 6716 resin is formulated for use with Circalok 6733 hardener.
  • 45-Minute Working Life: The 6716/6733 mixed system has a typical 45-minute working life at 25 deg C.
  • Electrical Assembly Encapsulation: The 6716/6733 system is used for potting low- and high-voltage electrical and electronic assemblies.

Applications

Resin component for the Circalok 6716/6733 silicone system used to pot and encapsulate low- and high-voltage electrical and electronic assemblies.

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.

Physical Properties
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

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.

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.

Mechanical Properties
Elongation
Elongation is the process of lengthening something. It is a percentage that measures the initial, unstressed, length compared to the length of the material right before it breaks. It is commonly referred to as Ultimate Elongation or Tensile Elongation at break.
