Ready-to-Use Silicone Potting Compounds
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.
Potting compounds that meet UL 94 V-0 have passed a test for flame retardance.
Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Light-Activated Silicone Potting Compounds
Pot multiple electronics in a flash—these compounds don’t require mixing and they cure within seconds under UV light. 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.

Harsh Environment Coatings for Electronics
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. Also known as conformal coatings, they’re thinner than potting compounds, so they flow into the smallest contours of your components to cover them completely.
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 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).

Optically Clear Coatings for Electronics
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, they won’t cloud in hot, humid environments. That means they’re great for use outdoors, such as on signs and instrumentation panels. Also known as conformal coatings, these coatings are thinner than potting compounds, flowing into the smallest contours on your device to cover it completely. Silicone 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. They cannot be sold in California due to local regulatory limits on VOCs.

Component-Concealing Coatings for Electronics
Hide proprietary information on electrical components while also protecting them from moisture, dust, and static. All it takes is a single thin layer of these black coatings. They’re often used to protect custom parts while prototyping. Place them under a UV curing lamp to fully harden them in just 5 seconds. Made of urethane, they resist chemicals and scratches and won’t crack in low temperatures. That means they’re great for harsh environments. These coatings meet UL 94 V-0 for flame retardance.
Also known as conformal coatings, they’re thinner than potting compounds, so they flow into the smallest contours to cover your parts completely. They also don’t require a potting box or other container. Dispense these coatings with a gun (sold separately).

EMI/RFI Shielding Coatings for Electronics
Protect sensitive electronic parts, enclosures, and prototypes from electromagnetic interference (EMI) and radio frequency interference (RFI) with these coatings. Also known as conductive paint, these coatings block EMI and RFI from disrupting electrical, data, and radio signals, which can cause circuit malfunctioning and data loss.
For best adhesion, apply to clean, oil-free surfaces. If applying to highly chemical-resistant plastics such as PVC and PTFE, use a primer first.
Carbon acrylic coatings are made with ground carbon powder mixed with acrylic. They're best for RFI and low-frequency shielding applications, such as protecting jumpers and resistors in initial prototypes, since they're not as conductive as nickel and silver acrylic coatings. They don’t contain metal, so they’re also great for electronics where metal-filled coatings could cause malfunction, such as metal detectors.
Nickel acrylic coatings are made with nickel flakes mixed with acrylic. They’re the best in our offering for protecting magnetic components, since they absorb and redirect magnetic fields. While not as conductive as silver acrylic coatings, they still protect against a broad spectrum of EMI and RFI frequencies. Use them to repair small circuits on circuit boards and to coat devices such as meter and scanner housings. They have good corrosion resistance.
Silver acrylic coatings are made with silver flakes mixed with acrylic. They’re the most conductive coatings in our offering, so they protect against the broadest spectrum of EMI and RFI frequencies. They’re also the most corrosion resistant. Use them to coat portable electronics, access panels, industrial cabinets, and engine control modules.

Conductive Adhesives for Electronics
An alternative to solder, these flexible, silver-filled adhesives accommodate joint movement. Use them to bond electrical components and repair circuits.
Epoxy adhesives are two-part adhesives that need to be mixed together. The size listed is the combined total of the two parts.
Thermoplastic adhesives are one-part adhesives that don’t need to be mixed. Dry to the touch and faster and easier to apply than two-part adhesives, they’re best for use on automated assembly lines. Often used to join solar cells in solar panels, these adhesives make instant electrical connections without flux at lower temperatures than soldering. Since they attach to solar cells with heat and slight pressure, they limit stress cracks that can form when soldering. These adhesives can also be used as a bridge between multiple solar panels.
