LOCTITE 279
Harmonization Code : 8001.20 | Unwrought tin: Tin alloys
Main features
- High-Strength Thread Retention
- Threaded and Cylindrical Bonding
- Wide-Temperature Threadlocking Range
Product Description
LOCTITE 279 is a one-component red, high-strength anaerobic dimethacrylate adhesive for locking and sealing threaded connections. It also bonds closely fitting cylindrical components, giving one grade a defined role across threaded and retaining assemblies. The uncured liquid has a specific gravity of 1.12 and a viscosity of 600 to 700 mPa s by ISO 3104. On 3/8 x 24 grade 2 steel nuts and bolts, prevail torque reaches at least 10 N m after one hour and at least 17 N m after 24 hours at 22 deg C. Typical applications use the product from -55 to 150 deg C.
Key features
- High-strength threadlocking: Locks and seals threaded connections where a high level of strength is required.
- Dual assembly fit: Also bonds closely fitting cylindrical components for retaining applications.
- Torque development: Prevail torque reaches at least 10 N m after one hour and at least 17 N m after 24 hours at 22 deg C on grade 2 steel fasteners.
Applications
Applications include locking and sealing threaded connections and bonding closely fitting cylindrical components in the stated -55 to 150 deg C operating range.
