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).

Potting compounds that cannot be sold to California exceed local regulatory limits on VOCs (volatile organic compounds).

Encase electronic assemblies in a layer of silicone 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).

Cartridge potting compound requires a gun (sold separately) to dispense; use it with the included mixer nozzle.

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).

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ACTIVITY after your order ships.

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.

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.

Use these coatings on tanks to create a low-friction lining that prevents bubble formation and turbulence in the liquids within. These thick coatings can also be used in chutes and on foundations for a smooth, glossy surface that resists abrasion, chemicals, and extreme temperatures once cured. Apply with a brush or roller. The size listed is the combined total of the two parts.

Longer-lasting than antislip tape, these coatings contain grit to provide traction. They’re good for areas with pedestrian traffic.

Water-based epoxy coatings are clear and can be applied over nearly any surface, even old coatings, without altering their appearance. These two-part coatings come with a mixer that attaches to a hand-held drill and a roller cover to apply them once mixed. The size listed is the combined total of the two parts.

Apply gallon-sized water-based coatings with a roller.

These coatings meet UL 723 and are rated Class A by ASTM E84—the highest rating available—for their ability to limit the spread of flames and generation of smoke. Use them in kitchens, furnace areas, and ships on plastic, metal, wood, and masonry. Apply with a brush, roller, or sprayer. The size listed is the combined total of the two parts.

Clear coatings are frequently used on wood—use one coat on sealed wood and two on unsealed. They can be used outside without breaking down, but prolonged exposure to UV light may cause them to yellow.

White coatings are frequently used on walls, ceilings, doors, and stairwells.

Use these primers on metal surfaces in enclosed occupied areas, such as hospitals, schools, and offices. They have excellent resistance to moisture and corrosion and bond well to metal to extend the life of paint and coatings. Apply with a brush, roller, or sprayer.

Extend the life of your footwear with these abrasion- and water-resistant epoxies. Stronger and more durable than most footwear materials, these epoxies are often used to coat and repair high-wear areas prone to rips, cracks, and water exposure, such as safety toes. They permanently bond to leather, plastic, and rubber. Each cartridge includes enough epoxy to coat the toes on one pair of shoes or boots. They fully harden in 24 hours and dry with a gloss finish, which can be rubbed away for a matte finish.
