LOCTITE 572
Harmonization Code : 3910.00.00.90 | Silicones in Primary Forms; Others
Main features
- Medium-Strength Thread Locking
- Thixotropic Migration Control
- Metal Pipe and Fitting Sealing
Product Description
LOCTITE 572 is a medium-strength, thixotropic dimethacrylate sealant for threaded metal pipes and fittings. Its rheology reduces liquid migration after application, and the material cures anaerobically when confined between close-fitting metal surfaces. At 25 deg C, typical specific gravity is 1.25; typical Brookfield RVT viscosity is 28,800 to 77,000 mPa s at 2.5 rpm and 14,400 to 28,600 mPa s at 20 rpm with spindle 6. After 24 hours at 22 deg C, typical breakaway torque is 7 N m on M10 steel nuts and bolts, while breakloose torque reaches 20 N m when the same fasteners are pre-torqued to 5 N m, both by ISO 10964.
Key features
- Reduced liquid migration: Thixotropic rheology reduces liquid product migration after application.
- Medium-strength locking: Anaerobic cure provides medium-strength locking and sealing of close-fitting metal threads.
- Steel fastener breakaway torque: Typical M10 steel fastener breakaway torque is 7 N m after 24 hours at 22 deg C by ISO 10964.
Applications
Locking and sealing threaded metal pipes and fittings.
