LOCTITE 609 is a green, high strength methacrylate ester acrylic retaining compound designed for the bonding of cylindrical fitting parts. The product cures in the absence of air between close-fitting metal surfaces. Typical applications include rotor to shafts in fractional and sub-fractional horsepower motors. Locks bushings and sleeves in housings on shafts. Augments press fits. Advantages of LOCTITE 609 • Low viscosity • Prevents loosening and leakage from shock and vibration • Augments press fits • Tested to the lot requirements of Military Specification Mil-R-46082B

LOCTITE 660 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps occurs without the need for re-machining. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. LOCTITE 660 exhibits excellent gap cure characteristics and is also suitable for retaining shims. LOCTITE 660 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps occurs without the need for re-machining. The product cures when confined in the absence of air between close-fitting metal surfaces and prevents loosening and leakage due to shock and vibration. LOCTITE 660 exhibits excellent gap cure characteristics and is also suitable for retaining shims. Advantages of LOCTITE 660 • Ideal for repairing worn parts without re-machining • Enables re-use of worn bearing seats, keys, splines or tapers • Suitable for retaining shims • P1 NSF Reg. No.: 123704

LOCTITE 680 is a green, high strength, methacrylate ester acrylic liquid designed for the bonding of cylindrical fitting parts, particularly where low viscosity is required. The product prevents loosening and leakage from shock and vibration. It provides robust curing performance. It works on active metals (e.g. mild steel) and on passive substrates (e.g. stainless steel and plated surfaces). Advantages of LOCTITE 680 • Low viscosity • Provides robust curing performance • Cures when confined in the absence of air between close-fitting metal surfaces • Offers high-temperature performance and oil tolerance • Tolerates minor surface contaminations from various oils • Certified to ANSI/NSF Standard 61 for use in commercial and residential potable water systems not exceeding +82 °C
