Epoxy Potting Compounds
Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. They have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. All require a mixer nozzle and gun to dispense.
3M DP460EG and DP4XLEG also require a plunger to dispense.
Loctite® ES1001™, ES1902™, and ES2500™ come with a mixer nozzle.
Compounds that cannot be sold to Canada are restricted by product labeling requirements.

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).

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) compounds because they don’t need heat or UV light to cure.
Potting compounds that meet UL 94 V-0 have passed a test for flame retardance.
Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Urethane Potting Compounds
Encase electronic assemblies in a layer of urethane for protection from dust, moisture, chemicals, mechanical shock, and vibration. Urethanes withstand a wide range of temperatures and are the best choice for cold-temperature applications. They have excellent flexibility, good chemical and moisture resistance, and provide good electrical insulation.
Cartridge potting compounds can be applied precisely through the included mixer nozzle. You’ll need a dispensing gun (sold separately). US2350™ also require a 4:1 plunger (sold separately) to dispense.
Bottle potting compounds are easier to apply in high volumes than cartridge potting compounds. Mix the compounds together and pour them over components inside potting boxes and other containers. If mixing introduces any air bubbles, put the mixture in a vacuum chamber.
Compounds that cannot be sold to the listed areas are restricted by product labeling requirements.

Urethane Potting Compounds for Harsh Environments
From shore to sea floor, these potting compounds are formulated for permanent submersion in water—even salt water. Use them to protect circuits and splices in pumps, underwater lighting, and other underwater electronics from corrosion and chemicals. Made of urethane, they withstand a wide range of temperatures, especially cold underwater conditions. They provide good electrical insulation and have excellent flexibility. Since they’re more flexible than epoxy compounds, they’re often used to protect against vibration and impact.
Mix the two parts of these compounds together and pour them over components inside a potting box or other container. If mixing causes air bubbles, put the mixture in a vacuum chamber to remove them.

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.

Adjustable-Flexibility Heat-Transfer Potting Compounds
Mixing required—resin and hardener come in two separate jars or in a jar and syringe and must be combined before applying. Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application. They're formulated to draw heat away from sensitive electronic components, so they 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.
The size listed is the combined total of the two parts.
