Optically Clear Conformal Coatings

Protect LEDs, solar cells, and fiber optics with a coating that’s clear enough to see through. These coatings let optimal light pass through and repel dust and moisture, so they won’t distort your view of what’s underneath. Made of silicone rubber, they won’t cloud in hot, humid environments. That means they’re great for use outdoors, such as on signs and instrumentation panels. These coatings are thinner than potting compounds, flowing into the smallest contours on your device to cover it completely. Silicone rubber conformal coatings are the most flexible kind of conformal coating, so they won’t crack or peel from vibration. To protect sensitive equipment, these coatings also prevent static discharge.

Simply spray these coatings on your device without needing a potting box or other container. Since they cure at room temperature, you won’t need UV lights or cure ovens either. You can remove them if necessary.

These coatings are IPC certified for use with circuit boards. They also meet UL 94 V-0 for flame retardance.

Cannot Be Sold Outside North America—These coatings cannot be sold outside of North America due to regulatory limits on VOCs (volatile organic compounds).

Conformal Coatings for Harsh Environments


Bottle	Cartridge

High humidity, harsh chemicals, water submersions, and salt are no match for these electronic coatings. They also resist UV light, so they’ll work outdoors. Use them on circuit boards, sensors, and LED drivers in heavy machinery. They’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely.

PVDF—PVDF coatings are more flexible than epoxy coatings. They’re IPC certified for use on circuit boards. You can also use them to protect against corrosion on metal joints. To apply, brush or spray them on, or dip your components in.

Epoxy—Epoxy coatings resist impact and wear better than PVDF coatings, and they work in higher temperatures. You can also use them as an adhesive. For controlled pouring, they’re thickened with silicate. These coatings are autoclavable, and they’ll even cure underwater. Dispense them with a mixer nozzle and a gun (each sold separately).

Flame-Retardant Epoxy Potting Compounds


Cartridge	Can

Protect circuit boards and other electronics from fire and heat. These self-extinguishing compounds meet UL 94V-0 for flame retardance and withstand temperatures up to nearly 400° F. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration. Since they’re epoxies, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators. These compounds have the consistency of honey once they’re mixed, so they seep into crevices to encase intricate components.

Cartridge—Cartridge compounds dispense through a mixer nozzle for precise application. Use them with a dispensing gun.

Can—Can compounds are easier to apply in high volumes than cartridge compounds. Mix them together and pour them over components inside containers, such as a potting box. If you see air bubbles after mixing, put the mixture in a vacuum chamber to remove them.

Cannot Be Sold to Canada—These compounds cannot be sold to Canada.

Optically Clear Two-Part Silicone Rubber Potting Compounds


Loctite® Cartridge	Bottle

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 rubber 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).

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

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

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

Gel—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.

Light-Activated Silicone Rubber Potting Compounds

These compounds dry quickly when exposed to UV light allowing you to handle the potted items sooner. Made of silicone rubber, 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.

Reusable Silicone Rubber Potting Compounds


	Bottle Potting Compounds	Cartridge Potting Compounds

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 rubber, 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 Potting Compounds—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 Potting Compounds—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.

Flexible Epoxy Potting Compounds

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).

High-Temperature Epoxy Potting Compounds

Jar and Syringe

Bottle

Protect circuit boards and other electronics where high heat is a concern but you don’t need to transfer that heat elsewhere. These compounds are a good middle ground between standard epoxy compounds and heat-transfer compounds. They work at temperatures twice as high as standard epoxy compounds. However, they don't conduct heat as well as heat-transfer compounds so they're not the best choice for circuit boards that run for long periods of time. Harden these compounds at room temperature—they don’t require an oven to harden like heat-transfer compounds do.

Since they’re an epoxy compound, they won’t break down from chemicals or moisture. They’re also excellent electrical insulators and withstand a wide range of temperatures. Use them to shield components from dust, moisture, chemicals, mechanical shock, and vibration.

Jar and Syringe—Jar and syringe compounds are the consistency of honey once they’re mixed, so they’ll seep into the crevices of a circuit board and encapsulate intricate components. Use the syringe for precise application.

Bottle—Bottle compounds are easier to apply in higher volumes than jar and syringe compounds. Mix them together and pour them over components inside containers, such as a potting box. If air bubbles occur after mixing, you can put the mixture in a vacuum chamber to remove them.

Cannot Be Sold to Canada—Some compounds cannot be sold to Canada due to product labeling requirements.

Optically Clear Epoxy Potting Compounds

Cartridge

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, 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. All require a mixer nozzle and gun to dispense.
