Features and Benefits

Ethyl cyanoacrylate/aliphatic ester adhesive designed as a fast curing, low strength adhesive for locking metal and plastics fasteners.
LOCTITE® 425 is a dark blue ethyl cyanoacrylate/aliphatic ester adhesive designed as a fast curing, low strength adhesive for locking metal and plastics fasteners. It is designed for pre- or post-application. Fixture speed can be increased by using a LOCTITE cyanoacrylate activator - e.g. SF 7113. It is typically used in applications with an operating range of -65 °F to +185 °F (-54 °C to +85 °C).
  • Cures within 2 minutes on plated metal and plastics fasteners with full strength in 24 hours
  • Used for tamper proofing the heads of screws or potentiometers
