1. Product Overview

LOCTITE® 4014™ is a cyanoacrylate adhesive designed for fast room temperature fixturing. It is a one-part, low-viscosity liquid that cures with humidity and is ideal for bonding plastics and metals. This adhesive is suitable for medical device assembly and meets ISO 10993 biocompatibility standards.


2. Applications

  • Bonding plastics and metals
  • Medical device assembly (ISO 10993 tested)
  • Applications requiring heat resistance
