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.

Make castings and fill voids with these two-part pourable epoxies. The size listed is the combined total of the two parts.

Certificates with a traceable lot number and product shelf life are available for these products. Download certificates from ORDER HISTORY after your order ships.

These surface fillers can be used on vertical surfaces without sagging. They repair cracked, worn, and damaged surfaces. The size listed is the combined total of the two parts.

Mix these two-part epoxy surface fillers to create a strong repair in wet environments or underwater. Use them to repair cracked, worn, and damaged surfaces. Size listed is the combined total of the two parts.

Putty fillers come in a stick with 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 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 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.

A safe alternative to mercury in thermometers and thermostats, gallium transfers heat and electricity without toxic vapor that can be inhaled. Also known as Galinstan. Its low melting point means it's liquid at room temperature. When used next to parts that generate concentrated heat, it dissipates the heat quickly, making it good thermal interface material. It also allows electricity to pass throughout it, so it's often used in switches and electronics that must bend and flex.

Gallium clings to both metallic and nonmetallic surfaces such as glass and quartz. However, it eats away at most metal when used at high temperatures and dissolves aluminum even at ambient temperatures.

When choosing gallium, keep in mind its composition. The higher the gallium and indium content, the better it is at transferring heat. Gallium with tin reduces the melting point, but also decreases how well it transfers heat.

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.

Thermoplastic 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.

Fill gaps up to 0.02" to secure worn unthreaded cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air.

Primer (sold separately) cleans the surface and decreases the time to reach full strength. It is recommended when working with aluminum, stainless steel, and titanium; black-oxide finishes, and cadmium and zinc coatings.

Even on oily surfaces, these retaining compounds keep their hold. Use them to fill gaps up to 0.015" to secure worn cylindrical metal parts such as shafts, bearings, and press-fit assemblies. These retaining compounds begin to harden once coated surfaces are pressed together, blocking exposure to air. They meet NSF/ANSI 61 safety standards for use with drinking water systems.

Compounds with low locking strength prevent threads from loosening due to vibration and can be adjusted without tools.

Compounds with high locking strength require both heat and a hand tool to unthread.

Protect metal with these low-odor, water-based, UV-resistant coatings. They contain 316 stainless steel flakes, which provide durability and superior corrosion resistance. Apply with a brush, roller, or sprayer.

These zinc-rich coatings offer the protection of hot-dip galvanizing to keep iron and steel free of rust and corrosion. They're designed for outdoor use, but can also be used indoors in well-ventilated areas.

Coatings with 99% zinc withstand temperatures up to 750° F.

Apply coatings in a can with a brush, roller, or sprayer.

Coatings that cannot be sold to Canada are restricted by product labeling requirements. Coatings that cannot be sold to the Los Angeles area, CA, CO, CT, DE, MD, NY, RI, and UT are restricted by VOC regulations.
