Developed and manufactured in the United Kingdom, these sustainable, PFAS-free solutions are specifically engineered to meet the stringent precision cleaning and surface preparation requirements of modern industrial surface treatment sectors.
EnviroTech Europe has announced the global availability of its next-generation vapour degreasing formulations, ProSolv® 5408e
and ProSolv® AS-1.
As manufacturers across the aerospace, automotive, electronics, medical, and defence fields face intensifying regulatory and environmental scrutiny, the demand for high-performance, compliant chemical surface treatments is at an all-time high. EnviroTech Europe’s latest formulations demonstrate that environmental responsibility and uncompromising cleaning performance can coexist seamlessly within a single surface treatment process.
Vapour degreasing remains a cornerstone of industrial surface preparation due to its reliance on the physics of phase change. By boiling the solvent to create a stable vapour zone, the process allows fresh condensate to continuously coat components suspended within it. This completely dissolves oils, greases, machining fluids, waxes, and particulate residues, which then drain away under gravity without requiring mechanical scrubbing or agitation. Operating as a closed loop, the system continuously distills and recovers solvents via cooling coils, delivering rapid, highly repeatable, and residue-free results for even the most delicate topographies.
Engineered for critical surface treatment applications where failure is not an option, ProSolv® 5408e features an exceptionally low surface tension that enables it to rapidly wet surfaces and penetrate micron-scale features, tight clearances, and blind holes.
Key industrial specifications include:
- High Solvency: A Kauri-Butanol (Kb) Value of 98, enabling the removal of a broad spectrum of heavy contaminants.
- Environmental Credentials:
Fully RoHS compliant, PFAS-free, featuring zero Ozone Depletion Potential (ODP) and a Global Warming Potential (GWP) of less than 1.
- Operational Safety:
Non-flammable (no flash point) with a mid-range boiling point of 46°C. Its stable chemistry eliminates the need for stabilizers or routine testing, and it is classified as non-hazardous for transport.
- Process Compatibility:
Ideal for both conventional and ultrasonic-assisted closed-loop vapour degreasing equipment, leaving components dry with non-volatile residues below 10 ppm.
For lighter soil loads and highly sensitive materials, EnviroTech Europe offers ProSolv® AS-1. Serving as a direct, eco-friendly replacement for legacy HFE, HFC, and HCFC solvents, AS-1 is designed for flushing, monosolvent use, or as a rinsing agent in co-solvent and bi-solvent surface treatment applications.
Key performance highlights include:
- Controlled Solvency: A mid-range Kb Value of 44, providing effective cleaning without being aggressive on sensitive sub-assemblies or delicate substrates.
- Material Compatibility:
Extensively tested with zero adverse effects observed on stainless steel, aluminium, copper, brass, and common engineering alloys.
- Thermal Stability: A mid-to-high boiling point of 54°C ensures stable vapour phase performance and clean, residue-free evaporation.
- Safety & Compliance:
Non-flammable, PFAS-free, zero ODP, and a GWP of less than 1.
Approved and actively deployed across sectors ranging from oxygen cleaning and avionics to power generation and motorsport, the ProSolv® range provides a future-ready answer to evolving chemical regulations.
