Technical data sheet for Loctite 270 anaerobic threadlocking material, detailing properties, curing performance, and usage instructions.
Loctite 270 is a single‑component anaerobic threadlocking material that cures when confined between close‑fitting metal surfaces, providing high strength for heavy‑duty applications such as studs in motor housings and pump fasteners. The sheet describes typical applications, uncured material properties, and curing performance under various conditions.
Key specifications include specific gravity, viscosity, flash point, and mechanical strength values for both uncured and cured states. Environmental resistance, storage recommendations, and handling precautions are also provided, along with general usage directions and safety notes.
| Specific Gravity @ 25 °C | 1.1 |
|---|---|
| Viscosity @ 25 °C (mPa·s) | 400–600 |
| Flash Point (TCC) °C | >93 |
| Breakaway Torque (typical) N·m | 26 |
| Prevail Torque (typical) N·m | 36 |
| Coefficient of Thermal Expansion (K‑180 ×10⁻⁶) | K‑180 ×10⁻⁶ |
| Thermal Conductivity (W·m⁻¹·K⁻¹) | 0.1 |
| Specific Heat (kJ·kg⁻¹·K⁻¹) | 0.3 |
The typical breakaway torque is 26 N·m (range 16 to 36 N·m).
No, it is not normally recommended for use on plastics, especially thermoplastics that may stress‑crack.
The flash point is greater than 93 °C.
