The aerospace industry demands exceptionally high cleanliness standards, where even microscopic residues such as oils, flux, or particulates can negatively impact coating adhesion, bonding strength, corrosion resistance, and overall component reliability. As aerospace components become more complex and performance-critical, manufacturers face increasing pressure to achieve consistent, ultra-high cleaning quality while maintaining efficient and reliable production processes.
At the same time, many existing cleaning solvents pose growing environmental, health, and regulatory challenges. These legacy solvents are associated with high environmental impact and worker exposure risks, making long-term compliance increasingly difficult. As sustainability requirements tighten across the aerospace sector, manufacturers are actively seeking safer, more environmentally responsible cleaning solutions—creating the need for next-generation alternatives like Next 5408/Next HD Pro.
Introduction of Next 5408
Next 5408/Next HD Pro is a nonflammable precision cleaning solvent specifically designed for high-performance vapor degreasing applications. Formulated as an azeotropic mixture of trans-1,2-dichloroethylene (t-DCE) and hydrofluoroether (HFE), it delivers stable, consistent cleaning performance while ensuring safe and efficient operation
Key Features:
- Boeing-Approved (BAC-5408 / PSD 6-77) The next Next 5408/Next HD Pro has been formally approved by Boeing, which means that it meets the aerospace industry's highest standards for vapor degreasing performance, stability, and materials compatibility.
- Low Toxicity, PFAS-Free Formulation The solvent is formulated to minimize health risks with low toxicity and contains no PFAS. PFAS (Per- and Polyfluoroalkyl Substances) are known for resisting heat, water, and oil, making them useful in various applications such as non-stick cookware, water-repellent coating, stain-resistant fabrics. PFAS are often called “forever chemicals” because they do not break down easily in the environment. This means they can accumulate in water, soil, and living organisms over time.
The chemical structure of PFAS
- Non-Flammable and Zero Ozone Depletion Potential With a non-flammable blend and zero ozone depletion potential (ODP), Next 5408/Next HD Pro enhances safety and environmental performance compared to legacy solvents.
- Excellent Solvency Power (KB value 94) Its high solvency power ensures efficient removal of residues, greases, and contaminants for precision cleaning.
As aerospace standards continue to evolve, cleaning solutions must keep pace with both performance and sustainability demands. Next 5408/Next HD Pro offers a balanced approach, delivering reliable, high-precision cleaning while supporting safer operations and environmental responsibility. For manufacturers aiming to strengthen compliance without compromising performance, it represents a practical step toward the future of aerospace cleaning.
