Permabond F201HV - New hydrogen-ready, toughened, anaerobic sealant!


Permabond launches new hydrogen-ready, toughened, anaerobic sealant F201HV!


Permabond F201HV meets the requirements of Inorm KE214 and has been approved for use with hydrogen by official gas testing organisation KIWA.


This high strength, high performance toughened anaerobic adhesive is a breakthrough for the gas industry. In a bid to counteract global gas shortages and reduce gas costs for customers, the industry has been exploring the option of mixing hydrogen with natural gas for domestic supplies. With this comes certain challenges as hydrogen molecules are much smaller, more searching and more explosive than natural gas molecules. It is therefore essential that gas connections and pipe joints are sealed securely, with a sealant approved for use with hydrogen.


Permabond F201HV can be used to seal threaded metal pipe joints, or it can be used on concentric metal parts that slot together. Unlike conventional anaerobic thread sealants, F201HV is not brittle. Its core-shell toughening enables the cured material to flex, allowing for differential thermal expansion and contraction, and meaning that it can be used to seal dissimilar metals, such as brass and copper.


Permabond F201HV is the ideal sealant for manufacturers and installers of hydrogen-ready boilers, cookers, gas meters, heating systems and pipework. Its high strength, toughened formulation provides a permanent sealing solution, reducing the risk of loosening, accidental damage or tampering, all of which could otherwise result in hydrogen leakage.
