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).

Insulating Adhesives for Electronics
Cyanoacrylate
 |
Bottle |
Cyanoacrylate adhesives dry more quickly than epoxy adhesives. They’re also known as super glue. Use them to secure coils of wire. To create adhesion, they require an accelerator (included with some adhesives).

Single-Use Packet |
Epoxy adhesives are two-part adhesives that need to be mixed. The size listed is the combined total of the two parts.
Model Number 2151—Loctite® 2151 resist salts, mild acids, and oils. They can also handle sudden impacts and shocks.
ASTM E595—Adhesives that meet ASTM E595, a standard used by NASA, release almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

Optically Clear Epoxy Structural Adhesives
 |
Cartridge |
For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.
These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.
