About Paint and Protective Coatings

Epoxy Potting Compounds

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.

Optically Clear Epoxy Potting Compounds

Clear enough to read through, these UV-resistant potting compounds allow optimal light transmission for use with LEDs, solar cells, and fiber optics.

Ready-to-Use Silicone Potting Compounds

No mixing required—these potting compounds come ready to apply.

Two-Part Silicone Potting Compounds

Optically Clear Two-Part
Silicone Potting Compounds

Clear enough to read through, this UV-resistant potting compound allows optimal light transmission for use with LEDs, solar cells, and fiber optics.

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.

Urethane Potting Compounds

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.

Heat-Transfer Potting Compounds

Formulated to draw heat away from sensitive electronic components, these potting compounds have higher thermal conductivity than standard potting compounds.

Adjustable-Flexibility
Heat-Transfer Potting Compounds

Change the mix ratio of these heat-transfer potting compounds to achieve the right hardness for your application.

Heavy Duty Coatings for Electronics

Thinner than potting compounds, these rigid and wear-resistant coatings flow easily into small spaces between electrical components. Use them to secure and insulate hardware on printed circuit boards.

Electrical

Cable Repair Resins

Protect and insulate electrical connections, and repair damaged insulation.

Potting Boxes

Use these open boxes with adhesive for electronics (also known as potting compound) to encase electronic assemblies and protect them from vibration, tampering, moisture, and corrosives.

Adhesives

Insulating Adhesives for Electronics

Tack wires to coil forms or secure and insulate hardware on printed circuit boards. These adhesives require an accelerator.

Mixer Nozzles for Two-Part Adhesive Cartridges

To simultaneously mix and dispense two-part adhesives, attach these mixer nozzles to a dual cartridge.
