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.

Conductive Surface Fillers for Electronics

A high silver content allows these surface fillers to conduct electricity and heat. Use them to fill gaps and rebuild missing material on electrical connections or to assemble new components.

Surface fillers in one-time-use packets and jars come as two parts. The size listed is the combined total of the two parts.

Volume resistivity and surface resistivity measure how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.

Thermal conductivity measures a material’s ability to transfer heat. The higher the rating, the more heat it transfers.

Fuel-Resistant Surface Fillers

Also known as sloshing compounds, these two-part epoxies bond to rough and rusty surfaces in fuel tanks to repair leaks and prevent further corrosion. They withstand permanent immersion in fuel, oil, and harsh solvents. Use them with metal, plastic, and fiberglass tanks. Mix the smaller can with the bigger one and pour into your fuel tank. Rotate the tank to coat the interior and dump out any excess. Allow to cure overnight. Size listed is the combined total of the two parts.

1.5-pint container can treat a 10-gallon fuel tank. 3-pint container can treat a 20-gallon fuel tank.

Epoxy Potting Compounds

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.

Heat-Transfer Potting Compounds

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.

Paint for Metal

Paint metal surfaces to stop rust from starting and prevent existing rust from spreading. Scrape rusty areas clean before application. Although primer is not required for use on all materials, it can be used to prepare any surface to maximize the life and corrosion resistance of paint.

Acrylic paint is water-based and can be cleaned up with soap and water. It’s also known as latex paint. Paint with a 7-day overall dry time resists weather and mild chemicals once fully dry.

Apply paint in a one-gallon can with a brush, roller, or sprayer.

Paint that cannot be sold to the regions listed exceeds local regulatory limits on VOC (volatile organic compounds).
