Epoxy Potting Compounds for Harsh Environments
Tough enough to be permanently submersed in seawater, these compounds protect sensitive electronics, such as circuit boards, semiconductors, and sensors in harsh environments. They resist moisture, salt, and chemicals, so you can use them in corrosive oil, marine, and mining applications. These compounds can also be used within autoclaves. Because they are epoxies, they are rigid, resist wear, and create excellent electrical insulation. They withstand a wide range of temperatures, and this formulation won’t crack or split as components heat up and cool down.
They come in a cartridge, so you can apply them precisely. To dispense, they require a mixer nozzle and gun (both sold separately).

Coolant-Resistant Surface Fillers

Repair small leaks and cracks in coolant systems for commercial vehicles and industrial equipment. These surface fillers meet ASTM D3147 for their ability to stop leaks in engine cooling systems. Pour them into your coolant to fix both internal and external leaks. They contain ceramic microfibers and copper particles to create a permanent seal. They’re compatible with antifreeze and other coolant system additives.

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.

Surface Fillers for Plastic


Use these two-part fillers to rebuild cracked or worn plastic surfaces. The size listed is the combined total of the two parts.
Surface fillers in a cartridge come with a mixer nozzle, but require a gun (sold separately) for dispensing. For best results, use a primer (sold separately).
Surface fillers in a stick have a resin on the outside and a hardener on the inside. Cut the desired amount from the sticks, knead to a uniform color to mix, and press into place. Use with most rigid and semi-rigid types of plastic. They meet NSF/ANSI 61 for use with drinking water.
