LOCTITE 620 High Temperature Retaining Compound, 50ml, for Engine-Adjacent and Thermally Stressed Cylindrical Assemblies
Standard retaining compounds are formulated for room-temperature and moderate-heat service, and lose significant bond strength when exposed to the sustained high temperatures generated by engine-adjacent components and thermally stressed assemblies. Supplied by JHEARs Aerospace, LOCTITE 620 is the high-temperature rated retaining compound for cylindrical assemblies that will see genuine thermal cycling and elevated operating temperatures in service. It fills the gap in press-fit and slip-fit joints and holds the assembly together through both heat and vibration conditions that would degrade a standard bonding compound well before the next scheduled maintenance interval.
For engineers assembling components in areas of an aircraft where proximity to engine heat, exhaust systems, or high-cycle thermal loading means temperature resistance is a specification requirement rather than a preference, LOCTITE 620 provides the combination of cylindrical retention strength and high-temperature stability that the application demands. The 50ml tube provides a practical working quantity for workshop and line assembly use where precise, controlled application to cylindrical joint surfaces is the requirement.
Spec: LOCTITE 620 high-temperature retaining compound, PN 62040. 50ml. Anaerobic cylindrical retaining formula rated for high-temperature service. Suitable for press-fit and slip-fit metal cylindrical assemblies subject to elevated operating temperatures and thermal cycling. High shear and tensile retention strength.
Who this is for: Aircraft engineers and mechanics assembling engine-adjacent components where sustained high temperatures rule out standard retaining compounds, MRO technicians working on cylindrical assemblies subject to significant thermal cycling in service, and engineering professionals who need a permanent high-temperature retaining compound for bearing, bushing, and shaft retention in thermally demanding locations.
FAQ
What is the maximum service temperature of LOCTITE 620?
LOCTITE 620 is rated for continuous service temperatures up to 150 degrees Celsius, with intermittent peak temperature resistance up to 200 degrees Celsius. For assemblies exceeding these temperature ranges, consult the LOCTITE technical data sheet for alternative high-temperature retaining compound options suited to your specific application.
How does LOCTITE 620 differ from LOCTITE 603 for cylindrical assembly applications?
Both LOCTITE 603 and 620 are high-strength cylindrical retaining compounds, but LOCTITE 620 is specifically formulated for elevated temperature service, making it the correct choice where thermal cycling and high operating temperatures are a factor. LOCTITE 603 is rated for standard temperature service and is more appropriate for assemblies that do not experience significant heat exposure in operation.
Can LOCTITE 620 bonded assemblies be disassembled for maintenance?
LOCTITE 620 is a high-strength permanent retaining compound and assemblies bonded with it are not intended for routine disassembly. Removal typically requires localised heat application to degrade the adhesive bond, followed by mechanical pressing or extraction of the component. Plan assembly permanence before selecting this compound for any joint that may require future maintenance disassembly.
