1. Product Overview

Fine-L-Kote HT High-Temp Silicone Conformal Coating is a fast-drying, high-temperature resistant coating designed to protect electronic assemblies from thermal breakdown. It offers excellent moisture and vibration resistance, flexibility, and dielectric strength, while maintaining electrical insulation properties at extreme temperatures up to 350°C. UL94 V-0 rated and IPC-CC-830B certified, it is compatible with spray, dip, and brush application methods, and includes a UV indicator for inspection. The coating cures rapidly and can be reworked or removed using standard conformal coating removal methods.


2. Applications

  • High-temperature electronic assemblies

  • Printed circuit boards in industrial, automotive, and aerospace environments

  • Components exposed to vibration, moisture, or extreme heat

  • Rework and repair operations requiring fast-drying, high-temperature protection
