LOCTITE® 444 is a low-viscosity, fast-curing cyanoacrylate adhesive specifically designed for bonding plastics and elastomers. It provides rapid fixture times at room temperature and is particularly effective on porous or acidic surfaces where conventional instant adhesives may cure more slowly. The product delivers strong bonds with minimal surface preparation, making it suitable for high-speed industrial assembly applications.
