Description
  • Thermal management for electronics. Dow DOWSIL TC-6020 Thermally Conductive Encapsulant is a two-part silicone elastomer that offers high thermal conductivity, excellent dielectric properties, and adhesion to aluminum. It is used in the manufacture of electrical and PCB products and modules, encapsulating assemblies while dissipating heat away from sensitive components.
  • Performance profile. Dow characterizes TC-6020 as a two-part, gray, roughly 2.7 W/mK thermally conductive encapsulant formulated to encapsulate and dissipate heat in electronics applications such as on-board chargers, automotive control units, and electric-vehicle power electronics. It is a heat-cure product with good flowability, allowing it to fill around components and provide both protection and a thermal path.
  • Environmental protection. As a thermally conductive encapsulant and pottant for PCB system assemblies, TC-6020 provides protection from harsh environmental conditions together with thermal management, combining mechanical and moisture protection with heat dissipation in a single potting operation.
  • Cure behavior and handling. Cure begins on mixing, shown by a gradual viscosity rise, then gelation, then conversion to a solid elastomer. Because thermally conductive materials contain higher filler levels, product stored for long periods should typically be agitated or rolled before mixing to redistribute filler. Always read the product and Safety Data Sheets before handling.

Recommended For

  • Encapsulating and potting PCB system assemblies
  • Electrical products and modules requiring heat dissipation
  • On-board chargers and automotive control units
  • Electric-vehicle power electronics
  • Assemblies needing combined thermal and environmental protection

Available Variants

  • TC-6020 PART A 1KG — Part A (white), 1 kg can
  • TC-6020 PART B 1KG — Part B (gray), 1 kg can
  • The two cans are the matched components of one system: white Part A and gray Part B are combined to form the cured, gray thermally conductive encapsulant. Both parts are required to use the product, so they are ordered together rather than as alternatives.

FAQs

What is DOWSIL TC-6020 used for?

It is a two-part thermally conductive silicone encapsulant used to pot and protect electrical products, PCB modules, and power electronics while dissipating heat. Dow highlights applications such as on-board chargers, automotive control units, and electric-vehicle power electronics, where both environmental protection and effective thermal management are required together.

How thermally conductive is it?

Dow characterizes TC-6020 as roughly a 2.7 W/mK thermally conductive encapsulant, meaning it is formulated to move heat away from components far better than an unfilled silicone. It also offers excellent dielectric properties and adhesion to aluminum, combining electrical insulation with a useful thermal path in one material.

Why is Part A white and Part B gray?

The two components are supplied in different colors so they can be visually distinguished and their blend confirmed during mixing. When Part A and Part B are combined and cure, the resulting encapsulant is gray. Both parts are required, since neither cures into the finished elastomer on its own.

Does the material need special preparation before use?

Thermally conductive encapsulants contain higher levels of fillers, so product that has been stored for a long period should typically be agitated or rolled before mixing to redistribute settled filler. This helps ensure consistent thermal and physical performance. Always review the product and Safety Data Sheets before handling.

How does it cure?

TC-6020 is described by Dow as a heat-cure product with good flowability, and cure begins as soon as the parts are mixed, progressing through a viscosity rise and gelation to a solid elastomer. Pot life and cure time depend strongly on temperature, so consult the data table for your process conditions.
