Mixing required—resin and hardener come in two separate jars or in a jar and syringe and must be combined before applying. 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.

The size listed is the combined total of the two parts.

Tested to meet ASTM E595, a standard used by NASA, these potting compounds release almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Use them to draw heat away from your components—they conduct heat better than standard potting compounds. Made of epoxy, they’re the strongest of the potting compounds, so they’re rigid and wear resistant. They’ll also resist breaking down from chemicals and moisture. These compounds are excellent at insulating current, and they’ll shield against dust, vibration, and shock.

To apply, mix the two parts together and pour them over components inside a container, such as a potting box.

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.

Loctite® ES1901™ comes with a mixer nozzle.

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 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 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. They cannot be sold to Canada due to product labeling requirements.

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).

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).

Handle potted items within minutes—these potting compounds dry quickly when exposed to UV light. For added strength and durability, cure them with heat. Since they’re epoxy, 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. You need a mixer nozzle (not included) and a gun and plunger (both sold separately) to dispense. The nozzle lets you apply these compounds precisely.

For maximum effectiveness, these compounds need to be heat cured after they’re cured with UV light. Overall dry time includes heat curing at 149° F.

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. They’re not for sale in Canada.

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

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.

Secure hardware on circuit boards while insulating current.

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. Epoxy adhesives that reach full strength in 120 hrs. are flexible, making them ideal for bonding dissimilar materials that may shift or expand differently under heat.

Adhesives that meet ASTM E595, a standard used by NASA, release almost no volatile emissions that could damage sensitive electronics, even in a vacuum.
