DOWSIL SE4445

Main features

  • Two-Component Electronics Silicone System
  • White/Charcoal Component Identification
  • 2.4 Relative Density

Product Description

DOWSIL™ SE 4445 CV Gel is a two-component silicone compound identified for electrical and electronics applications. The supplied Part A is a white liquid with a typical relative density of 2.4 and dynamic viscosity of 80 poise, while Part B is a charcoal liquid with a typical relative density of 2.4 and dynamic viscosity of 230 poise. Product-specific thermal performance, mix ratio, cure schedule, cured hardness, working time, gap capability, and final-state properties cannot be published because the referenced technical data sheet was not included in the supplied files. :contentReference[oaicite:0]{index=0} :contentReference[oaicite:1]{index=1}

Key features

  • Two-component silicone system: Supplied as separate Part A and Part B silicone compounds.
  • Distinct component colors: Part A is white and Part B is charcoal, supporting visual differentiation during handling.
  • Electronics-focused use: Both component safety data sheets identify electrical industry and electronics use.

Applications / Suitable for

  • Electrical industry and electronics applications

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

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.
