Clear enough to read through, these UV-resistant potting compounds allow optimal light transmission for use with LEDs, solar cells, and fiber optics. 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, these silicone compounds are the best choice for high-temperature applications and electronics exposed to thermal cycling. They have excellent electrical insulation and good moisture resistance but poor chemical and abrasion resistance. Also known as RTV (room-temperature vulcanizing).

Compounds in a cartridge come with a mixer nozzle for precise application. You need a gun (sold separately) to dispense.

Liquid compounds harden around your component to form a strong, durable, and permanent layer of protection.

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.

These compounds dry quickly when exposed to UV light allowing you to handle the potted items sooner. Made of silicone, they’re softer and more flexible than epoxy or urethane compounds, so they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so they’re often used with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to abrasion or chemicals. The tapered nozzle lets you apply them precisely.

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.

To simultaneously mix and dispense two-part adhesives, attach these mixer nozzles to a dual cartridge. Mixing elements help combine the two parts of an adhesive as it flows through the nozzle. A short nozzle with many mixing elements combines adhesive while minimizing the adhesive left in the nozzle after dispensing. Choose a nozzle that matches the connection type, size, and mix ratio of your adhesive cartridge.

A taper tip has a small opening for controlled dispensing.

A step tip allows you to trim the opening to the diameter you need.

Secure hardware on circuit boards while insulating current.

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).

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

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

For invisible bond lines, these adhesives dry clear. Epoxies are the strongest and most weather- and chemical-resistant structural adhesives. Choose an epoxy that hardens quickly for fast repairs, or one that hardens slowly to allow more time for positioning.

These have two parts that must be mixed. The size listed is the combined total of the two parts. Use cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.

0151 and E-30CL are suitable for fiber-optic applications.

Urethane adhesives are the most flexible, so they bond dissimilar materials and damp vibration.

The size listed is the combined total of the two parts. Use 1.64 fl. oz. and 1.69 fl. oz. cartridges with a dispensing gun and mixer nozzle to simultaneously mix and dispense adhesives.U-05FL, U-09FL, and U-09LV won't yellow.

Moisture, humidity, and immersion in water won't degrade the bond of these adhesives. For easy positioning, they begin to harden only when exposed to light. Use a dispensing gun with plunger (sold separately) to dispense adhesive.
