This company has developed two Loctite anaerobic retaining compounds that can reportedly perform at operating temperatures up to 180°C and show cure strength through oil contaminations and on passive metal surfaces.
“Loctite 638 and 648 offer customers increased reliability and greater heat resistance,” said Niamh O’Reilly, Ph.D., Product Development department. The newly developed adhesives reportedly guarantee secure bonding on insufficiently cleaned parts, solving a problem that is typical in many manufacturing processes. They can achieve excellent curing on all metals, including passive metal surfaces like stainless steel. This allows for more flexibility in substrates and designs.
