IMAGINE: Improved thermal
conductivity – 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 electronics
modules over time.
Dow Corning developed – and continues to broaden - a portfolio of silicone
thermal conductive gap fillers with different levels of thermal conductivity
that deliver greatly improved dispensability, significantly reduced
abrasiveness and stable performance for more reliable electronics in harsh
automotive underhood environments. Dow Corning® thermally conductive gap
fillers are soft, compressible, two-part silicone, high thermal conductivity
materials specifically formulated to process easily and effectively dissipate
heat from critical automotive electronics systems, such as engine or
transmission control units, braking and stability controls, sensors and other
Corning® TC-4525 Thermally Conductive Gap Filler has thermal
conductivity of 2.5W/m.K
Corning® TC-4515 Thermally Conductive Gap Filler has thermal
conductivity of above 1.5W/m.K

Improved reliability in harsh temperatures: Thermally Conductive Gap
Fillers effectively dissipate heat away from sensitive electronics. They
withstand peak exposure at 200°C, and perform reliably at operating
temperatures ranging up to 150°C.
Easy processing: These advanced thermally conductive silicone gap
fillers dispense easily from their original packaging with minimal to no
additional process preparation, making them well-suited for automated
application using standard meter mix equipment.
Effective assembly: Thermally Conductive Gap Fillers avoid slumping
on vertical surfaces during assembly. After cure, it maintains its vertical
stability even after long use. Select formulations incorporate glass beads to
control bond line thickness during assembly.
Cost-effective, fast cure: The platinum cure system enables fast,
controlled cure at room temperature, although cure times can be accelerated
further with heat to reduce manufacturing cycle times. No post-cure steps are
