LOCTITE® (LOCKTTLF) 648 High-Strength, Temperature-Resistant Retaining Compound

LOCTITE® (LOCKTTLF) 648 High-Strength, Temperature-Resistant Retaining Compound

LOCTITE® 648 is a green, low-viscosity, high-strength anaerobic retaining compound designed for bonding cylindrical fitting parts. It is ideal for applications such as securing gears and sprockets on gearbox shafts or rotors on electric motor shafts, where it reliably prevents loosening and leakage from shock and vibration. This compound provides a robust bond even in high-temperature environments and cures effectively on both active metals (like mild steel) and passive substrates (like stainless steel). A standout feature is its tolerance for minor surface contamination from various oils, such as cutting and lubrication fluids, often eliminating the need for a primer.

Key Features & Benefits:

• High-Temperature Resistance: Engineered to maintain high strength at service temperatures up to 180°C (355°F).
• Oil Tolerant: Cures reliably even on surfaces with minor contamination from industrial oils and fluids.
• Versatile & Primerless: Works effectively on both active and passive metal substrates without the need for a separate primer, saving time and cost.
• Low Viscosity: Its thin consistency is ideal for wicking into close-fitting parts, ensuring complete coverage.
• Rapid Fixture Time: Achieves handling strength in just 3 minutes, which helps to increase production throughput.
• Multiple Certifications: Holds numerous agency approvals, including DVGW for gas installations, WRAS for potable water, and NSF P1 for use in food processing areas.
• Quality Control: The compound is fluorescent under UV light, allowing for easy visual inspection of the application.
