Heat Sink Bonding Compounds


Tube	Pail	Jar	Syringe

Bond heat sinks to surfaces, eliminating air gaps for maximum heat transfer. These compounds are commonly used with transistors, diodes, rectifiers, and transformers.

Zinc Oxide—Zinc-oxide compounds create a more secure bond than silicone compounds.

Heat-Transfer Compounds


Cartridge	Can	Pail

Eliminate air gaps that cause heat loss and premature heater failure. These compounds mold around heat cable so it makes direct contact with pipes, pumps, and other parts.

450° F Maximum Temperature—Compounds with a 450° F maximum temperature don’t harden, so they maintain a tight seal even as the surface you’re heating expands and contracts. Since they’re waterproof, they also shield the surface from corrosion.

750° F Maximum Temperature—Compounds with a 750° F maximum temperature are often used with steam, hot oil, and glycol heat trace lines.

1,250° F Maximum Temperature and 2,200° F Maximum Temperature—Compounds with a 1250° F or 2200° F maximum temperature are often used with steam heat trace lines, strip heaters, and ring heaters.

Non-Bonding Heat Transfer Compounds

Also known as thermal paste, these boron-nitride compounds increase heat transfer between parts while preventing them from sticking. Unlike antiseize compounds, they don't conduct electricity, so you won't risk shorting out sensitive electronics. They're often used on thermocouple probes to improve accuracy. You can also use them in 3D printer heating blocks and other high-temperature areas to keep parts from fusing together.

Electrically and Thermally Conductive Grease

Syringe

Image of Product. Front orientation. Grease. Electrically and Thermally Conductive Grease, Jar.

Jar

A high silver content gives this grease excellent conductivity for applications where electricity and heat transfer are required. It is suitable for ESD (electrostatic discharge) and EMI (electromagnetic interference) shielding applications.

Grease lubricates most efficiently within the listed temperature range.

2 NLGI Grade—NLGI 2 is about the consistency of peanut butter.

Melting Temperature—Melting temperature is the point at which grease will fail and run out of equipment, leaving it to run dry.

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

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

Cannot Be Sold To—Product regulations restrict sales to the listed jurisdictions/areas.

Copper allows these lubricants to conduct electricity, while graphite gives them good chemical and corrosion resistance. Also known as thread lubricants, antiseize lubricants prevent threaded fasteners and close-fitting parts from locking together due to corrosion, contamination, or heat.

Loctite® LB 8008 C5-A Copper-Based Anti-Seize—Loctite® C5-A Copper-Based Anti-Seize lubricants can be used with salt water and petroleum-based chemicals.

LB 8065 C5-A Copper-Based Anti-Seize—Loctite® C5-A Copper-Based Anti-Seize lubricants can be used with salt water and petroleum-based chemicals. LB 8065 comes as a stick for no-mess application.

MIL-A-907 and MIL-PRF-907—Lubricants that meet MIL-A-907 and MIL-PRF-907 have been tested to prevent corrosion of copper and for antiseize properties when used with steel nuts and studs.

Cannot Be Sold To—Lubricants that cannot be sold to the areas listed exceed local regulatory limits on VOC (volatile organic compounds).

Epoxy adhesives are two-part adhesives that need to be mixed together. The size listed is the combined total of the two parts.

ASTM E595—Adhesives that meet ASTM E595, a standard used by NASA, produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

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 Gallium

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.

Penetrating Lubricants for Electrical Applications

Protect electrical components—these lubricants insulate and block moisture, preventing electrical malfunctions. They cut through dirt, grease, and rust to clean connections and relays, leaving behind a thin film for long-lasting protection.

Cannot Be Sold Outside United States—These lubricants cannot be sold outside the United States due to product labeling requirements.

Dielectric Strength—Dielectric strength measures the maximum voltage a lubricant can withstand without losing its insulating properties. The higher the dielectric strength, the better its quality as an insulator.

Conductive Surface Filler Pens for Electronics

Acrylic Plastic

Epoxy

Dispense ready-to-use conductive liquid to fill pits and small gaps on circuit board components. These pens are also used to sketch and repair conductive pathways.

Carbon Filled—Carbon acrylic plastic pens should be used where only a small amount of conductivity is needed, such as circuit boards in keyboards. Their high surface resistivity only allows a small current to pass.

Nickel Filled—Nickel acrylic plastic pens are best for general purpose repairs, such as bridges and traces in printed circuit boards. They have a medium surface resistivity, so they're a good balance between carbon acrylic and silver epoxy pens.

Silver Filled—Silver epoxy pens are the most versatile—use them for any type of repair as well as for repairs that require excellent conductivity, such as connecting through holes on circuit boards without adding jumpers, wiring, or solder. Since they have the lowest surface resistivity, they allow the most current to pass.

Cannot Be Sold To—Product labeling requirements restrict sales to the listed areas.

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.
