High-Temperature Surface Fillers for Metal


Epoxy Syringe	Epoxy Stick

Epoxy Can, Bottle

Repair and rebuild metal surfaces that are exposed to heat. These surface fillers withstand temperatures over 450° F. Fillers that have a mix ratio are multi-part fillers. The size listed is the combined total of the parts.

Syringe—Surface fillers in a syringe come with everything you need to make repairs.

Stick—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.

Plastic

Strip with Adhesive on

One Side

Plastic adhesives are one-part adhesives that don’t need to be mixed. Dry to the touch and faster and easier to apply than two-part adhesives, they’re best for use on automated assembly lines. Often used to join solar cells in solar panels, these adhesives make instant electrical connections without flux at lower temperatures than soldering. Since they attach to solar cells with heat and slight pressure, they limit stress cracks that can form when soldering. These adhesives can also be used as a bridge between multiple solar panels.

Conductive Surface Fillers for Electronics


Epoxy Jar	Single-Use Packet

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. They come as two parts. The size listed is the combined total of the two parts.

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

Electrical Volume Resistivity—Electrical volume resistivity measures how well a material opposes the flow of electricity. The lower the rating, the more electricity it conducts.
