LOCTITE AA 307, 50 ml
Loctite 307 Anaerobic Adhesive is a one-component urethane methacrylate adhesive designed for bonding close-fitting rigid metal parts. It cures in the absence of air when confined between metal surfaces, delivering strong and durable joints. Ideal for high-precision assemblies requiring excellent heat and solvent resistance.
Key features:
-
High shear and tensile strength
-
Temperature resistance up to 150 °C
-
Excellent chemical and solvent resistance
-
Cures without air between metal surfaces

Safety
Description
Loctite 307 is a one-part, general-purpose anaerobic adhesive based on urethane methacrylate chemistry. It cures when confined between close-fitting metal parts in the absence of air, forming strong, thermally stable, and solvent-resistant joints. Designed for precision bonding applications in metal assemblies, machinery, and maintenance operations.
Key properties
-
Chemical type: Urethane Methacrylate
-
Color: Clear to amber
-
Viscosity (25 °C): 1,000 – 3,000 mPa·s
-
Specific gravity: 1.1
-
Flash point: > 180 °C
-
Service temperature range: –55 °C to 150 °C
Performance
-
Tensile shear strength: 12 – 32 N/mm² (ASTM D1002)
-
Tensile strength: 30 – 50 N/mm² (ASTM D2095)
-
Cure time: 24 h at 22 °C with Loctite Activator 747
-
Recommended bond gap: 0.05 mm (max 0.1 mm)
-
Full cure: 24 hours
Resistance
-
Heat resistance: up to 150 °C
-
Chemical/solvent resistance: retains 75–100 % strength after 30 days exposure to solvents such as acetone, trichloroethylene, JP4, water/glycol, and humid air.
Applications
Ideal for:
-
Bonding close-fitting rigid metal parts
-
Use in machinery, repair, and precision assembly
-
Suitable for industrial maintenance and production lines
Storage & handling
Store unopened containers in a cool, dry place for maximum shelf life (minimum 12 months). Avoid skin or eye contact; wash immediately with soap and water after use.
