Medium-high strength threadlocker
LOCTITE® 290 is a green, medium-high strength threadlocker designed for the locking and sealing of threaded fasteners. Because of its low viscosity and capillary action, the product wicks between engaged threads and eliminates the need for disassembly prior to application (also referred to as wicking grade threadlocker). 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. Because of its flowable properties, the product is also suitable for sealing porosities in welds, castings and powdered metal parts.
Features and Benefits
Works on metal only
Requires heat for disassembly
Prevents fastener loosening on vibrating assemblies, e.g., pumps, gear boxes, or presses
Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws
