LOCTITE 42540 cyanoacrylate adhesive

The LOCTITE 425 is a fast-curing, low-strength cyanoacrylate adhesive ideal for locking and sealing metal and plastic fasteners. It bonds quickly on plated surfaces, with fixturing in under 2 minutes and full strength in 24 hours. Suitable for tamperproofing screw heads and potentiometers, the dark blue liquid has low viscosity and polymerizes with moisture. Application can be sped up with a cyanoacrylate activator. This adhesive is used in industrial, maintenance, and repair settings, functioning effectively from -54°C to +85°C, ensuring durability and precision bonding.
