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). Use a gun (sold separately) with the included mixer nozzle to dispense.

Encase electronic assemblies in a layer of epoxy for protection from dust, chemicals, moisture, mechanical shock, and vibration. The strongest of the potting compounds, epoxies are rigid and wear resistant. 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.

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.

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.

Also known as conformal coatings, use these coatings to protect circuit boards from moisture.

Acrylic and acrylic lacquer coatings dry quickly. Sprayon EL2000 resists grease, oil, and alkalies.

Silicone coatings have excellent chemical resistance for use in harsh environments.

Thinner than potting compounds, these coatings flow easily into small spaces between electrical components. They require an ultraviolet curing lamp to reach full strength. Use them to secure and insulate hardware on printed circuit boards.

Syringe coatings require a gun (sold separately) to dispense.

This coating is formulated for use in sensitive applications such as manufacturing semiconductors. Thinner than potting compounds, it flows easily into small spaces between electrical components. The coating begins to harden when exposed to UV light. Use it to secure and insulate hardware on printed circuit boards. It requires a gun (sold separately) to dispense.
