LOCTITE® 263™ is designed for the permanent locking and
sealing of threaded fasteners. 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® 263™ is particularly suited for heavy duty
applications such as studs into motor housings, nuts onto studs
in pump housings and other fasteners where high strength is
required. LOCTITE® 263™ provides robust curing
performance. It not only works on active metals (e.g. brass,
copper) 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.
