Features and Specifications

DOWSIL TC 4535 CV Thermally Conductive Gap Filler – Two part silicone gap filler for efficient heat dissipation in electronic applications.

DOWSIL TC 4535 CV is a two part, 3.4 W/mK thermally conductive silicone gap filler designed for use in electronic applications requiring reliable heat dissipation. This room temperature curing material (with optional accelerated heat curing) forms a soft, compliant elastomer ideal for filling gaps between heat generating components, such as PCB module assemblies, and heat sinks. Its flexibility ensures effective heat transfer even with minor surface irregularities.

The material is mixed in a defined ratio by weight or volume, ideally using a static mixer for both manual and automated dispensing to ensure homogeneity. The curing process occurs at a constant rate, regardless of thickness or confinement, resulting in a flexible elastomer without an exothermic reaction. Curing can be performed at room temperature or accelerated with heat. The cured material exhibits controlled silicone volatility, maintains its vertical position during application, and offers long term performance stability through temperature cycling up to 150°C, with short term exposure peaks up to 175°C.
