ADHESIVE: THREADLOCKER,50ML, LOCTITE 290MED STRENGTH

Loctite 290 is a liquid 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. 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. The product can also fill porosities in welds, castings and powdered metal parts. It requires heat for disassembly. Where cure speed is unacceptably long due to large gaps, applying an activator to the surface may improve cure speed. Activators SF 7471 and SF 7649 can be used with Loctite 290.

 

Features:

• Ideal for locking preassembled fasteners, e.g. instrumentation fasteners, electrical connectors and set screws
