This toughened anaerobic adhesive has been approved for use by Dutch-based gas testing organisation KIWA and meets the requirements of Inorm KE214. This is a breakthrough for the gas industry which is now looking to mix hydrogen into natural gas for domestic supplies to counteract gas shortages and reduce costs for customers. Hydrogen molecules are much smaller than natural gas, and much more searching, as well as more explosive, so it is vital any pipe joints or gas connections are properly sealed to prevent leaks with approved sealant material.
Permabond F201HV can be applied to threaded metal pipe joints which screw together or can be used on concentric, metal, slot-fit parts. Because of its core-shell toughening, unlike conventional anaerobic thread sealants, it is not brittle, and will flex to expand and contract with the joint. This allows the sealing of dissimilar metals, such as brass to copper, as the adhesive sealant will absorb differential thermal expansion and contraction stress. Its high strength, permanent sealing ability helps prevent tampering, accidental damage and joints loosening which could result in hydrogen leakage, according to Permabond.
