Techspray 1978-DP Silicone-Free Heat Sink Compound
Best thermal compound for electronics sensitive to silicone contamination.
The Techspray 1978-DP is a silicone-free heat sink compound designed for efficient thermal transfer in sensitive electrical applications. This compound is crucial where silicone contamination might otherwise lead to solderability issues and increased defects. It effectively draws heat away from components like thermocouple wells and thermistors, ensuring optimal performance. The formula is non-ozone depleting and offers excellent usability, as it resists separation, hardening, or cracking over time. This 4 oz tube provides a reliable solution for maintaining thermal integrity in demanding electronic environments.
