How can electrolyser stacks achieve fully automated assembly while ensuring chemical resistance, minimal hydrogen permeation, and reliable sealing?
✨ Market Trends: The growing global demand for hydrogen drives rapid automation of electrolyser production, requiring advanced sealing solutions that outperform traditional gaskets and O-rings. Materials with low hydrogen permeability, high chemical resistance, and adaptable mechanical properties are essential for alkaline, AEM, and PEM electrolysers.
✨ Applications: Wevo’s polyurethane, epoxy, and silicone adhesives and sealants are designed for bipolar plates, individual stack cells, and entire electrolyser assemblies. They enable CIPG and FIPG applications via dispensing or screen-printing, supporting precise, automated stack construction in both alkaline and proton-exchange membrane technologies.
✨ Highlights: WEVOPOX VP 414 and WEVOPUR systems demonstrate hydrogen permeation coefficients as low as 0.3×10^-8 cm²/s and maintain surface integrity in 35% KOH at 90 °C. Silicones such as WEVOSIL 28001, 28002, 28102, and thixotropic variants offer adjustable Shore A hardness (30–70), low hydrogen permeability, and chemical stability under acidic or alkaline conditions. Materials are compatible with high-temperature curing (100–140 °C) and long pot life for automated production.
✨ Product Advantage: By combining excellent adhesion, chemical resistance, and customizable elasticity, Wevo’s sealants and adhesives enable fully automated electrolyser assembly, reduced material replacement, and enhanced operational reliability.
