Loctite 425 Assure Blue Plastic Fastener is designed as a fast-setting, low-strength adhesive for locking medium-strength screw-lock, metal and plastic fasteners. The product is intended for pre- or post-application. Loctite 425 cures rapidly on coated metal and plastic fasteners; fixturing is achieved in less than 2 minutes and full strength in 24 hours. Fixture speed can be increased by applying a Loctite cyanoacrylate activator. This product is typically used in applications with an operating range of -54 degrees C to 85 degrees C.
