The all-new Dowsil TC-4015 Dispensable Thermal Pad
The all-new Dowsil TC-4015 is a two-part, thermally conductive, dispensable thermal pad. This innovative product is used for cooling electronic devices in LED lamps, luminaires, automotive and consumer electronics. Dowsil TC-4015 can be dispensed or screen printed into a variety of thicknesses and shapes. The dispensable pad offers a lower cost of ownership than a fabricated pad.
Dowsil TC-4015 Thermal Pad mixed viscosity is 103,000 Cp and the specific gravity is 2.6. The appearance of Part A is a white paste and Part B is blue paste. Once mixed together the material is blue. Working time of Dow Corning TC-4015 is 4 hours at 25°C, 32 minutes at 40°C. The cure time of this advanced material is 148 minutes at 40°C and 10 minutes at 125°C. Thermal conductivity is 1.7 W/Mk. The dielectric strength of this dispensable thermal pad is 450 volts/mil and it has a UL Flammability rating of V-0.
Dowsil TC-4015 Dispensable Thermal Pad is supplied as a two-component liquid system. When they are mixed, it cures to a flexible elastomer well suited to protect electronic devices. The various methods of this product include automated dispensing, stencil printing and screen printing. Silicone dispensable thermal pads have a temperature range between -45 to 200°C for long periods of time. At the high temperature, the durability of the pad is dependent on time and temperature.
