Loctite 648 Retaining Compound 50 ML

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.
