DOWSIL™ TC-4525 CV Thermally Conductive Gap Filler

A soft and compressible material once cured, designed to dissipate the heat from electronics mounted on printed circuit board to heat sink providing a reliable cooling solution for modules like an engine or transmission control unit.

Easier processing and long-term performance stability 

As automotive electronics contribute ever greater value to automotive safety, reliability, performance and comfort, they are also generating higher temperatures that can reduce the functionality and reliability of modules over time.

Dow developed – and continues to broaden – a portfolio of silicone thermal conductive gap fillers with different levels of thermal conductivity that deliver greatly improved dispensability, reduced abrasiveness (certain products) and stable performance for more reliable applications in harsh automotive under the hood environments.

Thermally conductive gap fillers from Dow are soft, compressible, two-part silicone, high thermal conductivity materials specifically formulated to process easily and to effectively dissipate heat from critical automotive parts, such as engine or transmission.
