    Coolant-Resistant Surface Fillers

    Image of Product. Front orientation. Surface Fillers. 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.

    Flexible Light-Activated Instant-Bond Adhesives

    Image of Product. Front orientation. Instant-Bond Adhesives. Flexible Light-Activated Instant-Bond Adhesives.
    Take your time to precisely align parts before bonding, and maintain flexibility afterward. These adhesives won't harden until you expose them to a compatible light source. They also remain elastic so the bond can bend without breaking.
    Thin Liquid—Seep into narrow gaps and joints that thick-liquid adhesives can't reach. Use when bonding close-fitting parts.

    Fuel-Resistant Surface Fillers

    Image of Product. Front orientation. Surface Fillers. 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.

    Urethanes are the most flexible adhesives, so they bond dissimilar materials and damp vibration.
    Some of these adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.
    Model Number UK U-05FL and Model Number UK U-09FL—Will not yellow.
    Cartridge—To mix and dispense these adhesives, you'll need a mixer nozzle and dispensing gun.
    Paste—Thicker than liquid adhesives but still spreadable—good for filling gaps and covering surfaces.
    Thick Liquid—Flow into narrower gaps than gels and pastes, but thick enough to stay put on uneven surfaces.

    Epoxy Potting Compounds for Harsh Environments

    Image of Product. Front orientation. Potting Compounds. 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).
