New Non-Silicone Thermal Putty from K.R. Anderson


The next step in low-stress gap filling materials is here!

KT-TY-SFP-45 is the newest silicone-free technology from HT Materials allows for the previously impossible use of a low-stress gap filler in applications where silicone is not allowed.

Product Highlights

Non-Silicone Thermal Putty

Very low compression force allows for low board and component stress and superb interface wet out regardless of substrate height, flatness or roughness.

Non-Silicone Thermal Putty

Allows for the replacement of almost all form stable gap filler pads with just one material.

Non-Silicone Thermal Putty

Can be used in any sized pattern and across a wide range of thickness (down to less than 1 mil).

Non-Silicone Thermal Putty

KT-TY-SFP-45 flows at 90 grams/min allowing for fast throughput during installation. It is well suited for manual dispensing, shot size-controlled dispensing equipment and automated dispensing lines.

It comes fully cured. Material properties will not change over the life of the application. As a result, there is no need to pry or scrape when the interfaced surfaces are opened. The used material can be wiped away or even reformed into a new “kiss” and re-used.

Unlike traditional thermal greases KT-TY-SFP-45 will not “pump out.”  Its thixotropic properties allow it to stay in place regardless of thermal cycles, shock and vibration.

4.5 W/m-K thermal conductivity places this material in the higher end of all commercial thermal interface materials. This combined with the exceptional conformability and wet out of this material makes for a remarkably low impedance thermal solution.

KT-TY-SFP-45 is RoHS compliant, UL 94 V-0 rated and has zero outgassing.

Typical Applications:

  • Military and Aerospace Opto-Electronic Components and Systems
  • Optical Telecom Equipment and Devices
  • Automotive Electrical Vehicles
