Plasmatreat (Steinhagen, Germany and Hayward, Calif., U.S.), is highlighting its latest innovations in aerospace surface preparation, presenting new findings on plasma-enabled bonding of advanced composites and anticorrosion treatments for metal structures.

On display at its booth are low-pressure, large-capacity plasma systems, including the company’s Openair Plasma technology, engineered for the aerospace industry’s most demanding applications — including the pretreatment of large composite panels, sandwich structures, honeycomb cores and other lightweight components commonly used in aircraft interiors, fuselage assemblies and structural bonding.

Designed for R&D and full-scale production, Plasmatreat’s low-pressure systems offer high-uniformity plasma treatment in large vacuum chambers; consistent, repeatable surface activation; and zero hazardous waste and compliance with sustainability initiatives.

Also at Plasmatreat’s booth are live plasma demonstrations, real-time surface consulting and daily technical sessions. Each day at 11:30 a.m., visitors are invited to attend a 30-minute technical session focused on plasma-based surface preparation, activation and process qualification. These sessions feature hands-on insights using the Brighton Science analytical tool, with a technical specialist from Brighton on hand to provide live data interpretation and expert guidance.

Plasmatreat also offers on-the-spot surface consulting throughout the event. Visitors are encouraged to bring their own material samples for real-time analysis and personalized feedback from the technical team. This hands-on approach is designed to help manufacturers evaluate surface readiness, improve adhesion, reduce rework and streamline bonding processes. 

The company is putting on a technical presentation, titled “Enhanced Bond Strength and Corrosion Prevention in Composite and Metal Structures Through Plasma Modification,” on Tuesday, Sept. 9 from 3:30 – 4:00 p.m. The presentation will highlight how atmospheric pressure plasma jets improve adhesive bonding by increasing surface free energy (SFE) and enabling covalent bonding — without the damage, contamination or environmental hazards associated with traditional surface treatments like grit blasting or chemical etching.
