Quick Overview
LOCTITE 263 is a red, dual-curing, methylacrylate ester fluorescent thread locking adhesive designed for permanent locking and sealing of threaded fasteners. It cures between tightly fitting metal surfaces and prevents loosening and leakage caused by impact and vibration. It is effective on active metals such as brass, copper, and passive substrates such as stainless steel and electroplated surfaces.
