Techsil TIM11150 (GB)20oz

Main features

  • 2.30 W/(m K) Thermal Conductivity
  • Embedded 50 um Glass Beads
  • Non-Corrosive Bonding Formulation

Product Description

Techsil® TIM11150 (GB) is a one-part, solvent-free acetone-cure RTV silicone sealant containing 50 µm glass beads for controlled self-gapping applications. The grey paste cures through atmospheric moisture to form a tough elastomer and is non-corrosive to copper and copper alloys. It combines fast skin formation with a typical cured thermal conductivity of 2.30 W/m·K and documented electrical insulation properties.

Key features

  • Thermally conductive cured elastomer: Provides a typical thermal conductivity of 2.30 W/m·K after seven days of cure at 23 ± 2 °C and 65% relative humidity.
  • Controlled self-gapping: Contains 50 µm glass beads to maintain separation in supported self-gapping applications.
  • Non-corrosive moisture cure: The one-part, solvent-free acetone-cure system does not corrode copper or copper alloys and reaches tack-free condition in four minutes under stated conditions.

Applications / Suitable for

  • Self-gapping applications requiring 50 µm glass-bead spacing
  • Sealing and adhesive applications where a one-part RTV silicone is suitable
  • Applications involving copper or copper-alloy surfaces where non-corrosive cure is required

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.

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

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.

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.
