DOWSIL TC-4015

DOWSIL TC-4015 Dispensable Thermal Pad is a two-part thermally conductive dispensable pad for filling thermal gaps in electronic assemblies. Parts A and B are white and blue pastes that mix to a material with a typical viscosity of 103,000 cP. The system has a typical 4-hour working time at 25 deg C and cures in 24 hours at 25 deg C, with heat acceleration to 10 minutes at 125 deg C. After cure, thermal conductivity is typically 1.7 W/(m K) and Shore 00 hardness is 50. It can be screen printed or dispensed into varied thicknesses and shapes for cooling PCB assemblies in LED, automotive, and consumer applications.

Key features

• About 1.7 W/(m K) Thermal Conductivity: Typical thermal-conductivity value applies to the cured dispensable pad.
• About 4-Hour Pot Life: Typical pot life applies to the mixed two-part material before cure.
• 24-Hour Cure at 25 deg C: Room-temperature cure can be accelerated with heat.

Applications

Cooling PCB assemblies in LED lamps and luminaires; automotive electronics; consumer electronics.
