Clear enough to read through, this UV-resistant potting compound allows optimal light transmission for use with LEDs, solar cells, and fiber optics. Use it 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 compound is the best choice for high-temperature applications and electronics exposed to thermal cycling. It has good moisture resistance but poor chemical and abrasion resistance. Silicone provides excellent electrical insulation. It’s also known as RTV (room-temperature vulcanizing). Use a gun (sold separately) with the included mixer nozzle to dispense.

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® 3336™, ES1001™, ES1902™, and ES2500™ come with a mixer nozzle.

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.

Loctite® ES1901™ comes with a mixer nozzle.

This potting compound meets UL 94V0 requirements for flammability. Use it to encase electronic assemblies for protection from dust, chemicals, moisture, mechanical shock, and vibration. Rigid and wear resistant, epoxy is the strongest of the potting compounds. It has excellent chemical and moisture resistance, withstands a wide range of temperatures, and provides excellent electrical insulation. Use the cartridge with a dispensing gun (sold separately) and the included mixer nozzle to simultaneously mix and dispense.

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. Use a gun (sold separately) with the included mixer nozzle to dispense.

US2350™ and US2650™ also require a 4:1 plunger (sold separately) to dispense.

This potting compound is formulated for use in sensitive applications such as manufacturing semiconductors. Encase electronic assemblies in a layer of material for protection from dust, moisture, chemicals, mechanical shock, and vibration. Urethane withstands a wide range of temperatures and is the best choice for cold-temperature applications. It has excellent flexibility, good chemical and moisture resistance, and provides good electrical insulation. Use a gun (sold separately) with the included mixer nozzle to dispense.

Encase electronic assemblies in a layer of material for protection from dust, moisture, chemicals, mechanical shock, and vibration. Hot-melt potting compounds have excellent flexibility, good chemical and moisture resistance, and withstand a range of temperatures. They provide good electrical insulation. Use 3M glue guns (sold separately) to dispense.

8" long sticks require a converter (sold separately) for use with the TC gun.

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.

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.

Also known as conformal coatings, use these coatings to protect circuit boards from moisture.

Acrylic and acrylic lacquer coatings dry quickly. Sprayon EL2000 resists grease, oil, and alkalies.

Silicone coatings have excellent chemical resistance for use in harsh environments.

This thermally conductive coating keeps electrical components cool by dissipating heat. Use it to bond transformers, transistors, and other heat-generating components to printed circuit boards and heat sinks.

Thinner than potting compounds, these coatings flow easily into small spaces between electrical components. Use them to secure and insulate hardware on printed circuit boards. Rigid and wear resistant, epoxies have excellent chemical and moisture resistance, withstand a wide range of temperatures, and provide excellent electrical insulation. Dispense with a mixer nozzle and a gun (each sold separately).

Tack wires to coil forms or secure and insulate hardware on printed circuit boards with these instant-bond adhesives. They require an accelerator to create adhesion.

An alternative to solder, these flexible, silver-filled adhesives accommodate joint movement. Use them to bond electrical components and repair circuits. The size listed is the combined total of the two parts.

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