Material Notes:
Description: THERM-A-FORM™ thermally conductive silicone elastomer products are dispensable form-in-place compounds designed for heat transfer without excessive compressive force in electronics cooling applications. These versatile liquid reactive materials can be dispensed and cured into complex geometries for cooling of multi-height components on a PCB without the expense of a molded sheet. Each compound is available in ready-to-use cartridge systems, eliminating weighing, mixing, and degassing procedures.Product Attributes: One-component moisture-cure RTV, supplied with primer 1086 (primer is not required for cure but promotes adhesion) and Non-acetic acid generatingInformation provided by Chomerics
