Product Description
DOWSIL™ TC-6010 Thermally Conductive Encapsulant is a two-part, flowable silicone encapsulation material designed to provide both thermal management and environmental protection for electronic and electrical assemblies. Featuring 1.2 W/m·K thermal conductivity, excellent dielectric strength of 22 kV/mm, and a self-leveling formulation, TC-6010 effectively dissipates heat from sensitive components while protecting them against vibration, moisture, contaminants, and electrical stress. The material cures with heat to form a soft, elastic silicone rubber that accommodates thermal expansion mismatch and enhances long-term reliability in demanding operating environments. Designed for automated or manual dispensing, TC-6010 is particularly well suited for on-board chargers, inverters, converters, transformers, power electronics, and PCB assemblies where both thermal performance and component protection are critical.

DOWSIL™ TC-6010: Thermally Conductive Encapsulant for Power Electronics
DOWSIL™ TC-6010 Thermally Conductive Encapsulant is a two-part, flowable silicone encapsulant designed to provide both thermal dissipation and electrical protection for electronic and electric components. With 1.2 W/m·K thermal conductivity, UL 94 V-0 flammability classification, excellent dielectric strength, and self-leveling flow after dispensing, TC-6010 is suitable for on-board chargers, inverters, converters, transformers, and other power electronics modules requiring heat dissipation from sensitive components.
Flowable encapsulation with thermal protection — TC-6010 combines 1.2 W/m·K thermal conductivity, self-leveling flow, elastic silicone protection, and strong dielectric insulation for power electronics assemblies.
The two-part silicone system cures with heat to form an elastic, thermally conductive rubber that helps protect sensitive circuits while transferring heat away from components.
Designed for encapsulating heat-generating electronics — suitable for power conversion modules, on-board chargers, inverter/converter assemblies, transformers, and PCB system assemblies.
TC-6010 fills and self-levels after dispensing, making it suitable for automated or manual mixing and dispensing processes where component coverage, dielectric protection, and thermal transfer are required.
