Epoxies, Etc.’s 20-1650 is a two-component silicone elastomer designed for applications in which a large amount of heat is emitted such as in oil drilling or high-voltage assemblies. Even for a silicone, which can operate under fairly high temperatures, the material outperforms. It operates in environments from -65 to +300°C (-85 to +572°F) and is formulated for increased thermal stability. The material is soft and flexible, and it moves with components rather than cracking or shrinking under stress. This makes it perfect for potting or encapsulating delicate components. Other benefits to using this material include its easy 1:1 mix ratio, relatively quick and air-free cure, and ability to cure in deep sections (beyond 1-2 in).
