LOCTITE 270 is a high-strength anaerobic adhesive designed for the permanent locking and sealing of threaded fasteners. This robust formulation prevents loosening and leakage caused by shock and vibration. It ensures reliable performance in demanding industrial environments, providing exceptional security for critical assemblies.
General Information of LOCTITE 270
LOCTITE 270 utilizes advanced acrylic technology, specifically a dimethacrylate ester chemical base. This one-component, low-viscosity green liquid cures anaerobically. Consequently, it hardens when confined between close-fitting metal surfaces, effectively preventing air exposure. This process eliminates the need for mixing, simplifying application.
Furthermore, LOCTITE 270 offers robust curing performance across various substrates. It performs exceptionally on both active metals like brass and copper, and passive surfaces such as stainless steel and plated materials. This product also provides high temperature resistance and tolerates minor oil contaminations. These include cutting, lubrication, anti-corrosion, and protection fluids, ensuring consistent adhesion even on slightly soiled surfaces.
Key Features & Technical Benefits
- Permanent Threadlocking: This adhesive ensures fasteners remain securely locked against severe shock and vibration. It prevents costly failures and maintains assembly integrity over time.
- Anaerobic Curing Mechanism: LOCTITE 270 cures reliably in the absence of air when confined between close-fitting metal surfaces. This targeted curing minimizes waste and simplifies application.
- Broad Substrate Compatibility: The formulation works effectively on both active metals, such as brass and copper, and passive substrates like stainless steel and plated surfaces. This versatility reduces inventory and expands application possibilities.
- High Temperature and Oil Tolerance: It maintains robust performance even at elevated temperatures and tolerates minor surface contaminations from various industrial oils. This ensures consistent strength in challenging operational conditions.
- High Strength Performance: Engineered for heavy-duty applications, it delivers superior breakaway and prevail torque values. This provides maximum security for critical threaded assemblies.
Typical Industrial Applications
This formulation is engineered for the following applications:
- Permanent locking of studs into motor housings.
- Securing nuts onto studs in pump housings.
- High-strength fastening for critical industrial machinery.
- Preventing vibrational loosening in heavy equipment.
- Sealing threaded assemblies against leakage.
