Why Specialised Coatings Are Critical to Aircraft Component Protection

From corrosion defense to thermal shielding – here’s what keeps aircraft flight-ready

Aircraft are built to endure some of the harshest environments on Earth and far above it. Every takeoff, landing and cruise altitude puts materials to the test. That’s why the coatings applied to aircraft components are far more than cosmetic. They’re engineered defenses, designed to handle the unique stresses of flight.

At Aerospheres, we work with aviation operators and MRO teams to deliver high-performance coatings, sealants and treatments that preserve integrity, extend component life and meet rigorous aerospace standards.

Let us explore the roles these coatings play and why they’re so important for protecting modern aircraft from the inside out.

Stopping Corrosion in Its Tracks

Aircraft operate in conditions that would break down most materials in no time, especially when exposed to moisture, salt spray, hydraulic fluids and atmospheric pressure changes.

That’s where anti-corrosion coatings come in. These specialised systems form a durable shield over metal surfaces, protecting areas like wing structures, undercarriages and fasteners from rust, oxidation and galvanic reactions.

We supply a wide range of corrosion-resistant primers, base coats and sealants, all sourced from trusted aerospace brands. As a trusted distributor, we help keep these products readily available despite global raw material shortages and extended lead times. Our ability to hold stock on behalf of both OEMs and customers helps maintain a steady supply chain, even when disruptions hit.

Thermal Protection in High-Heat Zones

Aircraft are complex systems and many of their components operate in high-temperature environments. 

Specialised thermal coatings are designed to:

• Insulate heat-sensitive parts

• Protect structural composites from temperature fluctuations

• Expand to form a fire-resistant barrier in emergencies

We supply a range of thermal barrier coatings that meet global aviation regulations. When it comes to scheduled overhauls or managing unexpected damage, our experienced team ensures the right materials are delivered quickly to help minimise turnaround times.

Durability Where It’s Needed Most

Cabin interiors and high-use zones like cargo holds and lavatories are constantly exposed to abrasion, impact, cleaning agents and general wear. These areas require coatings that combine durability with visual appeal.

Solutions include:

• Abrasion-resistant topcoats

• Soft-touch finishes for passenger areas

• Coatings compatible with regular disinfecting

As supply chains face delays of 12 weeks or more for some materials, our proactive sourcing and strategic regional stockholding allow MRO teams to stay ahead. We understand the urgency when high-traffic parts need fast, reliable repair. At Aerospheres, we make sure the right coatings are available when and where you need them.

UV Stability at Altitude

At cruising altitude, UV exposure is far more intense than on the ground, which can cause paints to fade, surfaces to degrade and adhesives to weaken.

UV-stable coatings are essential for protecting transparent panels and cabin plastics and ensuring the long-term performance of treated surfaces.

We partner with globally trusted coating manufacturers to supply UV-resistant formulations that help extend service life and reduce the frequency of rework, keeping aircraft looking sharp and performing efficiently.

Chemical and Electrical Compatibility

Today’s aircraft use advanced composites and integrated electronics that require highly compatible materials. The wrong coating can interfere with sensors or corrode electrical connectors.

That’s why we offer coatings and sealants tailored for:

• Fuel and hydraulic system protection

• EMI shielding and anti-static applications

• Avionics-safe and composite-compatible environments

We work closely with maintenance teams to match the right product to the right task, reducing trial-and-error and ensuring compliance.

Supporting MRO Teams

Aircraft maintenance never stands still and neither do we. With over three decades of experience supporting MRO operations across the UK and beyond, we know how critical it is to have the right materials on hand, whether for a scheduled inspection or an AOG event.

Our customers rely on us for our product knowledge and supply chain stability. As an authorised distributor for many of the world’s leading aerospace brands, we hold material in stock and offer strategic sourcing services that keep your maintenance operations running smoothly, no matter what’s happening in global logistics.
