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.

Compounds in a bottle are easy to apply in high volumes. Just mix and pour them over components inside containers, such as potting boxes.

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

Gel compounds form a soft and flexible layer of protection. You can also remove them if you need to re-access your components. They are rated IP68 once potted, so they seal out water even if submersed.

Tested to meet ASTM E595, a standard used by NASA, these compounds produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Light passes through them easily, so they’re ideal for protecting solar cells and fiber optics. Made of silicone, these compounds are softer and more flexible than epoxy and urethane compounds. That means they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so you can use them 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 chemicals or scrapes. They’re also known as RTV (room-temperature vulcanizing).

These compounds are easy to apply in high volumes. Just mix the two parts together and pour them over components inside a container, such as a potting box.

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.

Make repairs or changes to electrical components after they’ve been potted. While most compounds are permanent, these form a gel that bonds to itself, so you can peel it off without damaging your equipment. Often used in junction boxes, they form a water- and dust-proof seal that’s rated IP68 while also providing excellent electrical insulation. Made of silicone, they withstand a wide range of temperatures and are soft and flexible enough to resist shock and vibration. However, they’re not as strong as permanent potting compounds, so they don’t resist scrapes as well as those made of epoxy and urethane. They’re also not as chemical resistant as epoxy and urethane compounds.

These compounds won’t solidify once you open the container, so you have time to make adjustments when applying them. When removing them from your components, they mostly come off in one piece but there might be some residue left over.

Bottle compounds are a better choice for filling up new enclosures than cartridge compounds because you can pour more in at a time. They have a compartment for each component and require mixing.

Cartridge compounds have a nozzle for precise application. The nozzle can also fit into junction box knockouts, so it’s easier to fill up installed enclosures than it is with bottle compounds. They come ready to use with no mixing required and no waiting time.

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.

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.

Combine the flexibility of silicone with the durability of standard epoxy—these compounds are great for protecting sensitive electronics that need to flex or expand and contract. Because they’re an epoxy, they still have excellent moisture, chemical, and abrasion resistance. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. You can also use them as an adhesive since they’re also tacky.

They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

Used to insulate, create grips, and color-code components, these coatings resist high temperatures, light abrasion, and corrosion.

Rubber coatings withstand salt and acids. Although primer is not required for use on all materials, it can be used to prepare any surface to maximize the life of the coating. Apply topcoat to give coated surfaces a glossy finish that resists fading.

PVC plastic coatings can be used on nearly any surface, including rubber. They withstand salt, acids, alkalies, and gasoline. They also resist UV light, so they won’t lose their color when exposed to sunlight over long periods of time.

Coatings in a can can be dipped, brushed, or sprayed.

Coatings that cannot be sold outside of the United States do not meet product labeling requirements.

Primers and topcoats cannot be sold outside of the United States due to product regulations.

VOC (Volatile Organic Compounds) regulations restrict sales to the listed jurisdictions/areas.

These flexible, slip-resistant silicone coatings resist chemicals, block UV light, and encapsulate lead paint. They withstand temperatures up to 320° F. Apply with a brush, roller, or sprayer.
