LOCTITE® 648

Product Description

LOCTITE® 648 is designed for the bonding of cylindrical fitting parts, particularly where bond gaps can approach 0.15 mm and where maximum strength at room temperature is required. The product cures when confined in the absence of air between close fitting metal surfaces and prevents loosening and leakage from shock and vibration. LOCTITE® 648 provides robust curing performance. It not only works on active metals (e.g. mild steel) but also on passive substrates such as stainless steel and plated surfaces. The product offers high temperature performance and oil tolerance. It tolerates minor surface contaminations from various oils, such as cutting, lubrication, anti-corrosion and protection fluids. Typical applications include holding gears and sprockets onto gearbox shafts and rotors on electric motor shafts.
