LOCTITE 272 is a high-strength anaerobic adhesive designed for the permanent locking and sealing of threaded fasteners. This robust formulation ensures components remain secure under extreme operational conditions. It effectively prevents loosening and leakage caused by shock and vibration, thereby enhancing the reliability and longevity of critical industrial assemblies.
General Information of LOCTITE 272
LOCTITE 272 utilizes an advanced acrylic, dimethacrylate ester chemistry. This one-component, medium-viscosity, red-orange liquid requires no prior mixing, streamlining application processes. It initiates cure anaerobically, meaning it hardens reliably when confined between close-fitting metal surfaces in the absence of air. Furthermore, an activator can significantly accelerate its curing speed, offering flexibility in production schedules.
This formulation specifically targets high-strength threadlocking applications. It provides exceptional resistance to disassembly, making it ideal for critical connections. Typical applications include the permanent locking and sealing of large bolts and studs, specifically M25 and larger. Consequently, LOCTITE 272 enhances the structural integrity and operational safety of heavy-duty machinery and equipment.
Key Features & Technical Benefits
- Permanent Locking: Ensures threaded fasteners remain securely in place, resisting loosening from severe shock and vibration. This maintains assembly integrity over extended operational periods.
- Anaerobic Cure Mechanism: Cures reliably when confined between metal surfaces without air, preventing premature hardening and ensuring consistent performance. This allows for precise application and assembly time.
- High Strength Formulation: Provides superior breakaway and prevail torque, making it suitable for critical, high-stress applications where robust fastening is paramount.
- One-Component System: Eliminates the need for mixing, simplifying application procedures and reducing potential for errors. This contributes to increased efficiency and reduced material waste.
- Red-Orange Visibility: Offers clear visual confirmation of application, aiding quality control and ensuring proper coverage during assembly.
- Temperature Resistance: Maintains performance across a broad temperature range, ensuring reliability in diverse industrial environments.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Permanent locking and sealing of threaded fasteners in heavy machinery.
- Securing large bolts and studs, particularly those M25 and larger, in structural assemblies.
- Preventing loosening and leakage in high-vibration environments, such as automotive or industrial equipment.
- Enhancing the reliability of critical connections where disassembly is not routinely required.
