Epoxy Potting Compounds for Harsh Environments
Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

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.

Surface Fillers for Plastic
Use these two-part fillers to rebuild cracked or worn plastic surfaces. The size listed is the combined total of the two parts.
Surface fillers in a cartridge come with a mixer nozzle, but require a gun (sold separately) for dispensing. For best results, use a primer (sold separately).
Surface fillers in a stick have a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place. Use with most rigid and semi-rigid types of plastic. They meet NSF/ANSI 61 for use with drinking water.
