Coatings for defence and military technology
Defence and security technology systems are subject to extreme requirements in terms of reliability, durability and functional safety. Components must remain permanently operational worldwide under changing climatic, mechanical, chemical and electrical stresses – often without the possibility of subsequent replacement.
HÜNI+CO produces high-performance functional coatings for defence technology applications along the entire value chain. From individual functional parts to complex assemblies.
Our coating technologies for defence applications
HÜNI+CO offers a broad portfolio of high-performance functional coatings that are specifically designed to meet defence technology requirements:
- Highly corrosion-resistant protective systems (zinc flake coating)
- Chemical and media-resistant fluoropolymer coatings (e.g. ECTFE, ETFE, PFA, PTFE, FEP)
- Anti-adhesive functional coatings (e.g. PTFE, FEP, PFA)
- Electrically insulating coating systems (e.g. ECTFE)
- Combined protective and functional coatings
Depending on the application, our systems combine several properties in a single coating – tailored to the installation situation, specifications and application profile.
Added value for system houses and OEMs
In safety-critical projects, inconspicuous factors often determine performance and operational safety. Our coating solutions support defence and security technology companies in designing their systems to be reliable, durable and economical:
- Increased operational safety and system availability
- Extended service life of safety-critical components
- Reduced maintenance and servicing costs
- Support with the fulfilment of standards and specifications
- Technical advice as early as the development phase
Coatings in military and security-relevant applications do far more than just protect surfaces. They are an integral part of the system function and must withstand extreme loads.
The key requirements are:
- Long-term corrosion protection under extreme conditions
- Resistance to chemicals, media and fuel
- High mechanical strength and abrasion resistance
- Non-stick properties to ensure proper function
- Electrical insulation of live or sensitive components
- Stability under temperature changes and continuous load
In highly integrated systems, the coating quality has a significant influence on usability, maintenance intervals and life cycle costs.
In many defence systems, media, dust, sand, dirt or chemical residues must not be allowed to adhere to surfaces. Non-stick properties make a significant contribution to functional safety - especially for moving, encapsulated or difficult-to-access components.
Typical requirements are:
- Reduced adhesion of particles and environmental influences
- Avoidance of deposits caused by operating materials or chemicals
- Ensuring the mobility of mechanical components
- Easier cleaning, maintenance and decontamination
- Reliable operation under changing operating conditions
Anti-adhesive functional coatings reduce the risk of failure and extend the operating intervals of safety-critical systems.
Many defence and safety technology components are part of complex electrical or electronic systems. Coatings also fulfil the function of electrical insulation here.
Typical areas of application are:
- Insulation of current-carrying conductors and components
- Protection against leakage currents and short circuits
- Separation of different electrical potentials
- Additional safety in the event of moisture or condensation
- Protection of sensitive electronics in harsh environments
Electrically insulating coatings support functional safety and enable reliable operation even under extreme conditions.
In military systems, many components are deeply integrated into assemblies or complete systems. Replacement is often only possible with considerable effort or not at all.
Coatings must therefore:
- Remain stable over the entire product life cycle
- Be resistant to creeping degradation
- Minimise maintenance and servicing measures
- Function reliably with changing application profiles
High-performance functional coatings make a significant contribution to operational availability and system reliability.
Coating solutions are used in numerous areas of defence and security technology, including:
- Sensors, electronics and systems engineering
- Enclosures and functional parts
- Protection of sensitive components
- Electrical insulation and media resistance
- Energy, supply and safety systems
- Components for energy and media routing
- Corrosion protection against chemical and climatic influences
- Long-term stable solutions for critical infrastructure
