Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

7524A161 is solvent free. If the adhesive hardens in the tube, soften in warm water before dispensing.

Tested to meet ASTM E595, a standard used by NASA, these potting compounds release almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Use them to draw heat away from your components—they conduct heat better than standard potting compounds. Made of epoxy, they’re the strongest of the potting compounds, so they’re rigid and wear resistant. They’ll also resist breaking down from chemicals and moisture. These compounds are excellent at insulating current, and they’ll shield against dust, vibration, and shock.

To apply, mix the two parts together and pour them over components inside a container, such as a potting box.

Tested to meet ASTM E595, a standard used by NASA, these compounds produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Light passes through them easily, so they’re ideal for protecting solar cells and fiber optics. Made of silicone rubber, these compounds are softer and more flexible than epoxy and urethane compounds. That means they’re better at protecting against shocks and vibration. They also withstand a wider range of temperatures, so you can use them with electronics that heat and cool rapidly. These compounds are excellent electrical insulators, and they’ll shield your components from moisture and dust. However, they don’t hold up well to chemicals or scrapes. They’re also known as RTV (room-temperature vulcanizing).

These compounds are easy to apply in high volumes. Just mix the two parts together and pour them over components inside a container, such as a potting box.

Take your time positioning parts—these epoxies remain adjustable for at least 90 minutes before setting. Epoxies are the strongest and most chemical-resistant structural adhesives. They bond especially well on metal.

These adhesives come in two parts that need to be mixed. The container size listed is the combined total of the two parts.

Apply this glue-like tape for a no-mess alternative to liquid adhesives, hot melts, and staples. Also known as adhesive transfer tape, these rolls have a thin film of pressure-sensitive glue on a peel-away liner. They are thinner and more conformable than tape with adhesive on both sides.

Tested to meet ASTM E595, a standard used by NASA, this tape gives off almost no volatile emissions that could damage sensitive electronics, even in a vacuum. It’s more conformable than copper tape, so you can cover textured housings and round cables without leaving gaps for electromagnetic interference (EMI) to get in. When EMI makes contact, the conductive backing and adhesive convert it into heat and actively reflect it away. The conductivity of this tape also makes it great for electrical connections. Use it on surfaces that can’t be soldered.

Tested to meet ASTM E595, a standard used by NASA, this tape can mount sensitive electronics while releasing almost no volatile emissions that could damage them, even in a vacuum. Use it where temperatures fluctuate—its polyester backing keeps it from shrinking or stretching. And thanks to its acrylic adhesive, neither heat nor chemicals will cause it to peel off.

The 3M VHB adhesive on these rolls offers a strong hold that can replace rivets, spot welds, and other permanent fasteners. Also known as adhesive transfer tape, these rolls have a thin film of pressure-sensitive glue on a peel-away liner. They’re more conformable than tape with adhesive on both sides.

Protect sensitive electronics. Tested to NASA's ASTM E595 standards, this tape seals gaps while releasing almost no vapors, even in the vacuum of space. With Tedlar backing, it also stands up to chemicals and wear over time.

Made with fiberglass for durability and abrasion resistance, this electrical insulating tape also withstands high temperatures. The cloth can absorb electrical insulating varnishes.

Use this tape to wrap and splice cables or to mask components while soldering. It dissipates heat and is an excellent electrical insulator.

Tested to meet ASTM E595, a standard used by NASA, this tape releases almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Use it to repair and prototype circuit boards and shield components from EMI/RFI. With a copper backing and conductive adhesive, it’s useful for making electrical connections—current travels both along and through the tape. Unlike aluminum tape, it can be soldered. It’s also better at resisting chemicals.

Protect sensitive electronics at the molecular level—these ultra-thin, ultra-conformal coatings cover every inch of your components for applications where failure isn’t an option. They’ve even been trusted on satellites and medical devices. Use them to insulate current, prevent arcs and short circuits, and shield against moisture, chemicals, and gases. They’re better insulators than epoxy, urethane, and silicone coatings. Deposited as vapor in a vacuum chamber, they’re 90% lighter than spray and dip coatings. That means they’ll keep your items lightweight and won’t damage complex geometries. These coatings meet ASTM E595, a standard used by NASA, so they produce almost no volatile emissions that could damage sensitive electronics, even in a vacuum.

Note: These coatings must be applied using special parylene deposition equipment.

Use this tape to attach components to heat sinks and metal chassis walls in place of screws and other mechanical fasteners. It conducts heat away from sensitive electronics.
