Restore worn metal parts without machining

LOCTITE 660 Quick Metal is specially developed for bonding cylindrical metal parts with larger clearances. This makes it ideal for repairing worn bearing seats, keys, keyways, and tapered connections without the need for re-machining. The product cures when confined between closely fitting metal surfaces, preventing loosening and leakage due to shock and vibration.

Excellent gap-filling and curing properties

With high viscosity and excellent gap-fill properties, LOCTITE 660 can fill gaps up to 0.5 mm. This ensures a strong and durable bond, even with larger clearances. The fixture time on steel is approximately 15 minutes, providing a quick and efficient application.

• High viscosity for optimal gap-fill
• Fixture time on steel: 15 minutes
• Suitable for gaps up to 0.5 mm

Wide temperature range and chemical resistance

LOCTITE 660 withstands temperatures from -55°C to +150°C, making it suitable for various applications in diverse environments. In addition, the product is resistant to oils, lubricants, and most solvents, contributing to the reliability and durability of the bond.

• Temperature range: -55°C to +150°C
• Resistant to oils, lubricants, and most solvents

Applications and benefits

LOCTITE 660 is ideal for repairing and bonding:

• Worn bearing seats
• Keys and keyways
• Tapered connections
• Worn shafts and spun bearings

By using LOCTITE 660, worn parts can be reused without machining, saving time and costs. The product prevents corrosion between adjacent surfaces and ensures a strong, durable bond.

Recommended use and additional products

For optimal performance, it is recommended to use LOCTITE 660 in combination with activator LOCTITE SF 7649. This accelerates curing and improves adhesion on passive metals or at low temperatures. Make sure the surfaces are clean and grease-free before applying the adhesive.

• Use in combination with LOCTITE SF 7649 activator
• Ensure clean and grease-free surfaces for optimal adhesion
