Don’t Sweat Extreme Temperatures – 20-1650 Silicone Potting and Encapsulating Compound Can Withstand the Heat

20-1650, by Epoxies, Etc., is a two component silicone elastomer designed specifically for applications where 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, 20-1650 outperforms. It operates in environments from -65°C to +300°C (or up to 572° F).

20-1650 has been specially formulated for increased thermal stability. It is very soft and flexible and moves with components, rather than cracking or shrinking under stress. This makes 20-1650 perfect for potting or encapsulating delicate components.

Other benefits to using this material include its easy 1:1 mix ratio, its relatively quick and air-free cure, and its ability to cure in deep sections (beyond 1-2 inches).

In a world increasingly concerned with the reduction of toxic chemicals and the expense of shipping them, 20-1650 has the advantage of being solvent free so it is safer to handle than many potting systems and is non-regulated for shipping.
