Parylene has been used for over 40 years protecting defense and aerospace devices from failure from the harshest environments in sea, land, air, and beyond.

The unique vacuum deposition process of Parylene provides optimum protection superior to any urethane, silicone, and acrylic conformal coatings. With the ability to provide pinhole-free coverage, the devices are protected from sand, salt water, mold, and dust. It also performs in cryogenic conditions of outer space and temperatures of 125°C without any thermal or mechanical stress. Parylene is also used to prevent dendrite growth.

Paratronix® has been trusted since 1981 by all major military and aerospace contractors to apply our Parylene coating to their mission critical devices. Our team is always developing new advanced technologies for masking complex devices.
