Born2Bond: Anaerobic for thread fixing

Born2Bond anaerobic pipe sealing adhesives are a reliable and adaptable solution. It is also suitable for all types of threaded metal pipes and fittings, both new installations and preventive maintenance. Filling and sealing all voids, these one-part adhesives provide 100% surface-to-surface contact. In this way they provide a cohesive and durable connection that will not fail even when subjected to vibrations, extreme temperatures or chemicals. In this way, it is a convenient and cost-effective alternative to conventional sealing alternatives such as hemp or PTFE tapes. In addition, these adhesives eliminate the need for additional inventory.
