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).

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). Use a gun (sold separately) with the included mixer nozzle to dispense.
Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.
