Infalible Adhesives & Sealants for Hyrdrogen Sealing & Bonding
Infallible Adhesives and Sealants for Hydrogen Sealing and Bonding
Handling hydrogen poses lots of technical challenges, primarily containment; hydrogens low molecular size means it’s able to permeate most materials. Solutions for sealing hydrogen pipework therefore is crucial as leaks or gaps can have catastrophic outcomes.
With the production of green hydrogen on the rise, solutions for sealing and storage are increasingly important, without them, green hydrogen cannot become a sustainable energy source.
High performance thread sealants and anaerobic adhesives can be utilised throughout hydrogen production from electrolysers, to storage, to end use applications.
Specialist adhesives and sealants can be utilised for fail-safe hydrogen sealing:
- Anaerobic sealants fill in the air space, curing to a thermoset plastic, this stops leakages and loosening of joints due to heavy vibration or thermal expansion.
- Thread sealants bond threaded pipe components creating a permanent leak-proof seal.
Why Use Adhesives and Sealants for Hydrogen Bonding?
- No permeation
- Chemical resistance with a wide temperature range
- Good for irregular surfaces and small spaces
- Ideal for pipe sealing where heavy vibration and temperature changes are present
- Creates a permanent seal and seamless bond
- Good for spaces where an O-ring cannot be used like sealing flat surfaces
Where Can Adhesives and Sealants be Used in the Hydrogen Supply Chain?
- Pipe work and joints
- Valves
- Compressors
- Fuel cells
- Hydrogen sensors
- Structural bonding of non-metallic components
- Electrolysers
