Ready-to-Use Silicone Potting Compounds
No mixing required --these potting compounds come ready to apply. Use them to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They're also known as RTV (room-temperature vulcanizing).

Two-Part Silicone Potting Compounds
Encase electronic assemblies in a layer of silicone for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have good moisture resistance but poor chemical and abrasion resistance. Silicones provide excellent electrical insulation. They’re also known as RTV (room-temperature vulcanizing).
Cartridge potting compound requires a gun (sold separately) to dispense; use it with the included mixer nozzle.

Optically Clear Two-Part Silicone Potting Compounds
Clear enough to read through, this UV-resistant potting compound allows optimal light transmission for use with LEDs, solar cells, and fiber optics. Use it to encase electronic assemblies for protection from dust, moisture, mechanical shock, and vibration. Softer and more flexible than epoxies and urethanes with the widest temperature range, silicone potting compound is the best choice for high-temperature applications and electronics exposed to thermal cycling. It has good moisture resistance but poor chemical and abrasion resistance. Silicone provides excellent electrical insulation. It’s also known as RTV (room-temperature vulcanizing).
