Surface treatment for aerospace and space applications

Why surface treatment is important in aerospace and space

Such as composites, polymers, carbon fiber, and specialty metals are chosen for their strength, low weight, and resistance to harsh environments. However, many of these materials have naturally low surface energy, making it difficult for adhesives, coatings, or inks to bond properly.

Plasma and corona surface treatment solves this problem by modifying the molecular structure of the outermost surface layer. The process increases surface energy, removes organic contaminants, and activates the surface for optimal bonding, printing, or sealing. The result is strong, stable, and durable adhesion, even when exposed to vacuum, UV radiation, or extreme temperatures.

Proven technology for extreme environments

Tantec’s plasma and corona treatment systems are designed for environments where precision and reliability are essential. For over five decades, our equipment has been used by aerospace and defense manufacturers worldwide to prepare materials for the toughest missions.

Each system offers:

• Uniform and repeatable treatment for consistent results on complex shapes and materials
• Non-contact and dry process, ideal for delicate or heat-sensitive parts
• Compact, modular design for easy integration into R&D setups or automated lines
• Process monitoring and data traceability to ensure complete quality documentation
• Maintenance-friendly operation and long system life

From laboratory development to full-scale production, Tantec systems offer the control, documentation, and reliability that aerospace and space  applications demand.

Applications across the aerospace and space industry

Our surface treatment technologies are used in all phases of aerospace manufacturing—from early material research to assembly and system validation. Typical applications include:

• Satellite structures, honeycomb panels, and antenna assemblies
• Optical sensors, lenses, and precision camera modules
• Propulsion system components and composite enclosures
• Solar panels, flexible films, and protective coatings
• Carbon fiber composites and lightweight structural parts
• Electrical connectors, cable insulation, and wiring systems
• Printed circuit boards, microchips, and electronic assemblies
• Seals, gaskets, and polymer O-rings
• Encapsulation materials, polymer films, and adhesives
• Research and test setups in laboratories and vacuum chambers

Every surface matters—and with plasma or corona treatment, materials are optimized for adhesion, coating, and electrical performance under the most demanding conditions imaginable.

Designed for integration and flexibility

Tantec offers a wide range of customized systems for both atmospheric and vacuum environments.

Our vacuum plasma systems are ideal for treating components that require a clean, controlled atmosphere — such as sensors, printed circuit boards, or optical assemblies.

For larger or continuous production, atmospheric plasma and corona systems offer fast, inline treatment of films, panels, or cables, ensuring efficiency without compromising precision.

Each system can be customized with specific power levels, electrode configurations, and control interfaces to precisely match your process requirements. Whether you need stand-alone laboratory systems or fully automated production units, Tantec ensures seamless integration and reliable operation.
