LOCTITE^® 425 is a dark blue, cyanoacrylate-based adhesive specially designed as a fast curing, low-strength adhesive for locking metal and plastic fasteners. Ideal for pre- or post-application. Fixture speed can be increased by using a LOCTITE^® activator, such as LOCTITE^® SF 7113. It is typically used in applications with an operating range of -54°C to 85°C (-65°F to 185°F).
