Plasmalex launches eco-friendly and PFAS-free barrier coatings

Plasmalex, a specialist in advanced coating solutions, has introduced PlasmaGuard X, its latest addition to the realm of superior barrier coatings. PlasmaGuard X is a part of the PlasmaGuard range. Developed after extensive research and development, this innovation emphasizes the strong commitment of Plasmalex SAS, headquartered in Fuveau, France, to sustainability and an increased awareness towards the environment.

The PlasmaGuard series is known for its high-performance, ultra-thin, water-repellent and barrier coatings. The series serves to protect a broad spectrum of products such as consumer electronics, medical devices, PCBAs and a variety of nonwovens or nanofiber materials. Notably, these coatings are high-quality and eco-friendly, being entirely PFAS-free.

Expanding on the success of the initial PlasmaGuard coatings that debuted in 2023, the new PlasmaGuard X provides enhanced barrier and corrosion protection capabilities.

PlasmaGuard S, another product in the range, is a fully halogen-free nanocoating, generally applied at a thickness of 10-200nm. It possesses exceptional membrane breathability and abrasion resistance, and is transparent, leaving no impact on acoustics and conforming to biocompatibility standards for medical devices.

A dielectric barrier coating

Meanwhile, PlasmaGuard X is designed as a PFAS-free dielectric barrier coating. This multilayered coating, applied at a thickness below 1.5µm, outdoes traditional conformal coatings in terms of protection and thickness. PlasmaGuard X offers outstanding barrier strength vis-a-vis its competitors in the market, including acrylic, epoxy, silicone, and even parylene conformal coatings.

Europlasma SA, Pessac/France, conducted a range of robust tests to validate the exceptional barrier properties of PlasmaGuard X. These tests clearly show that PlasmaGuard X exceeds industry expectations, making it an optimal choice for applications where superior protection is vital.
