LOCTITE 272 is an anaerobic threadlocker specifically engineered for the permanent locking and sealing of threaded fasteners. This high-strength adhesive prevents loosening and leakage effectively, even under extreme operational conditions. It cures reliably in the absence of air between close-fitting metal surfaces. Consequently, it ensures robust assembly integrity against severe shock and vibration, enhancing overall system reliability.
General Information of LOCTITE 272
LOCTITE 272 utilizes an advanced acrylic technology, specifically a dimethacrylate ester chemical base. This formulation presents as a distinctive red-orange liquid in its uncured state. It functions as a single-component system, eliminating the need for pre-mixing. Furthermore, its medium viscosity ensures controlled and precise application, minimizing waste and simplifying the dispensing process.
The product employs an anaerobic curing mechanism. It initiates polymerization rapidly when confined between metal surfaces, deprived of atmospheric oxygen. An activator can significantly accelerate this process, particularly on inactive metal substrates or in applications involving larger bond line gaps. This ensures a consistently high-strength bond, crucial for critical industrial assemblies. The cured material exhibits excellent resistance to various chemicals and solvents, maintaining performance over time.
Key Features & Technical Benefits
- Permanent Locking: This adhesive ensures threaded fasteners remain securely in place. It effectively prevents unwanted disassembly, even in dynamic environments.
- Vibration Resistance: The cured product robustly resists loosening caused by severe shock and vibration. This significantly enhances the operational reliability and lifespan of mechanical assemblies.
- Anaerobic Cure: It cures only when confined between metal surfaces without air. This unique property allows for flexible assembly times and precise positioning before final cure.
- Single-Component System: No pre-mixing is required before application. This simplifies the dispensing process, reduces potential for error, and streamlines manufacturing workflows.
- High Temperature Performance: LOCTITE 272 maintains its strength and integrity across a broad temperature range. This ensures consistent performance in demanding thermal conditions.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Permanent locking and sealing of large bolts and studs (M25 and larger).
- Securing fasteners in critical thru-hole applications where high strength is paramount.
- Sealing internal threads in blind-hole assemblies to prevent leakage and corrosion.
