Next-generation, PFAS-free vapour degreasing solvent for critical cleaning in the aerospace industry

In the demanding world of aircraft and aerospace component manufacturing, highly effective precision cleaning is vital from production to final finishing. Components must be thoroughly degreased with no residue left behind.

Vapour degreasing remains the gold standard method for efficiency, safety, and performance, delivering superior cleaning power, using less energy, and requiring minimal floor space. The latest generation of vapour degreasing solvent cleaners offer high performance, environmentally friendly solutions, designed especially for the aerospace and aircraft industry, where critical cleaning is essential for the removal of heavy greases, oils, waxes, silicones, and non-polar flux residues.

EnviroTech Europe supply premium quality precision cleaning solvents, manufactured in the UK to the highest quality standards under strict quality control procedures. Advanced cleaning solutions that are safe, sustainable, and cost-effective - trusted by industry leaders across the aerospace sectors.

The Future of High-Performance, PFAS-free Cleaning
ProSolv®5408e is an advanced, next-generation cleaning solvent designed to meet the highest environmental and performance standards. Completely PFAS-free (free from Per- and polyfluoroalkyl substances), it features zero Ozone Depletion Potential (ODP) and ultra-low Global Warming Potential, making it a truly future-proof solution.

ProSolv®5408e enables the powerful removal of organic residues and oils, while remaining compatible with a wide range of plastics and metals. Exceptionally low surface tension and high solvency power enable it to penetrate deep into tight spaces, complex geometries, blind holes, and even micron-sized openings - ensuring thorough and reliable component cleaning.

Versatile and efficient for modern cleaning Systems
ProSolv®5408e is compatible with most solvent cleaning systems including one-tank or multi-tank immersion and vapour degreasing equipment, using ultrasonics or flush cleaning. It delivers outstanding performance in removing a broad spectrum of organic soils. Designed for energy efficiency and fast cycle times, it ensures low solvent losses, easy handling, and reduced environmental impact - helping you cut operating costs without compromising on cleaning quality. A few examples of its many applications are discussed below:

Bonding of honeycomb sections for composites
Removal of all contamination from aluminium honeycomb prior to epoxy resin bonding of the formed aluminium skin to produce lightweight high tensile structures for applications such as leading edges on aircraft wings and wind turbine blades. ProSolv®5408e is fully tested to aircraft industry standards.

Cleaning for fault testing of welds and castings
Another common use in the aircraft industry is in the cleaning of castings and metal fabrications before the use of NDT (non-destructive testing) fault detection fluids. Removal of all surface contamination is vital to expose faults. Vapour degreasing and vapour liquid cleaning with ultrasonics is a favoured method due to the excellent solubility of oils, greases and other soils, using one tank with very fast processing, and resulting in the parts emerging completely clean and dry. This is particularly relevant as part of the maintenance procedure for refurbishment of aircraft landing gearswhere surfaces can be heavily contaminated by hard to remove hydraulic oils, rubber and cement dust and grease.

Critical cleaning of oxygen and gas systems
EnviroTech Europe has a series of guides to using ProSolv®5408e for component cleaning to Oxygen standards and recommended cleaning methods involved, available on request.

Replacement for 3MTM NovecTM 72DE and 73DE Engineered Fluid
ProSolv®5408e is also a PFAS-Free direct replacement for 3MTM NovecTM 72DE and 73DE engineered fluids, used prominently in the aerospace, aviation and electronics industries, which are due to be phased out by the end of 2025.

TESTING
Flash Point ASTM D3828, Flammable limits ASTM E918, Stock Loss ARP1755B, IGA Intergranular attack, Stress corrosion of titanium alloys ASTM F945-1.
