Tested to meet ASTM E595, a standard used by NASA, these sealants fill joints and seams while releasing almost no volatile emissions that could damage sensitive electronics, even in a vacuum. Made of silicone rubber, they’re RTV (room-temperature vulcanizing), so they’ll fully harden at room temperature.

Elongation indicates flexibility—the higher the value is, the more a sealant can stretch.

A firm consistency and resistance to evaporation make this grease ideal for high-vacuum applications, such as flow meters, vacuum and pressure systems, and laboratory equipment. Apply directly to seals and O-rings to prevent drying and cracking.

Grease lubricates most efficiently below the maximum temperature.

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.

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.

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.

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.

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.

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.
