1. Product Overview

DOWSIL™ TC-5026 is a gray, flowable, non-curing thermally conductive compound designed for efficient heat dissipation in electronics. It offers:

  • Solventless formulation for clean application
  • Non-curing—no need for curing ovens
  • Flowable for easy dispensing
  • Thin Bond Line Thickness (BLT) for optimal thermal performance
  • Very low thermal resistance and high thermal conductivity
  • Silicone-based with thermally conductive fillers

2. Applications

DOWSIL™ TC-5026 is used for thermal management in high-performance electronic assemblies such as:

  • Microprocessor Units (MPUs) in servers, desktops, notebooks, and gaming consoles
  • PCB system assemblies requiring enhanced heat dissipation
  • Electronic devices with compact designs where heat buildup is a concern
  • Heat sink and chassis interfaces to improve overall thermal efficiency
