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.

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).
Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Heat-Transfer Potting Compounds
Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds. Use them to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxies are the strongest of the potting compounds. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation.
Cartridge potting compound requires a gun and mixer nozzle (each sold separately) to dispense.

Metal- and X-Ray-Detectable Structural Noncorrosive Silicone Sealants

With chemical and metal additives that are picked up by X-ray machines and metal detectors, these sealants are designed to help you comply with Hazard Analysis and Critical Control Point (HACCP) programs in food-processing facilities. Their blue color means they’re also easily spotted and removed if a piece falls into your line. They’re unpalatable to rodents, so they’re often used to seal entry points such as windows, doors, and wall panels to keep out pests.
Also known as neutral cure, these sealants are noncorrosive and won't discolor copper, brass, or concrete. They’re structural sealants, meaning they combine excellent sealing properties and high flexibility with the mechanical strength of an adhesive—they can even join dissimilar materials. Made of silicone, their resistance to UV light, moisture, and both high and low temperatures makes them suitable for both indoor and outdoor use. These sealants are room-temperature vulcanizing (RTV), so they’ll begin to cure as soon as they’re exposed to air. They’re non-sagging and won’t drip from vertical or overhead surfaces.
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values, the more joint movement a sealant can sustain.

Mildew-Resistant Silicone Sealants



Resistant to mold and mildew, these sealants are well suited to high-humidity environments. They’re non-sagging, so they won't drip from vertical and overhead surfaces. Made from silicone, sealants are RTV (room-temperature vulcanizing).
Elongation and joint compression/expansion tolerance indicate flexibility—the higher the values are, the more joint movement sealants can sustain. Sealants that are good for joining dissimilar materials also work well in environments with wide temperature fluctuation.
Dow Corning 786 meets NSF/ANSI 51 standards and is FDA compliant for direct contact with food.
Sealants that cannot be sold to Canada are restricted by product labeling requirements.
