Model Name: LOCTITE® 128068™
Technology: Acrylic Methacrylate Ester
Appearance: Purple, UV-fluorescent gel paste
LOCTITE 128068 is a high-viscosity, anaerobic flange sealant designed to form an in-place, flexible seal between close-fitting rigid metal flanges. It cures slowly when confined between metal surfaces, minimizing shimming and ensuring long-lasting sealing performance. With immediate low-pressure sealing capability and high resistance to thermal and chemical stress, this sealant is ideal for demanding industrial environments.
Typical applications include transmission housings, axle covers, and other components in the automotive, machinery, and heavy equipment sectors.
One-Component, Ready-to-Use: No mixing required
Anaerobic Curing: Cures when confined between metal surfaces and isolated from air
Flexible Seal: Accommodates minor flange movement
High Viscosity Gel: Prevents migration and shimming
Immediate Low Pressure Resistance: Suitable for low-pressure testing post-assembly
UV-Detectable: Aids in automated or manual inspection
