1. Product Overview

LOCTITE® EA E-214HP™ is a one-component, industrial-grade epoxy adhesive that requires heat curing. It develops tough, strong structural bonds with excellent peel resistance and impact strength. The cured adhesive provides superior thermal shock resistance, mechanical strength, and electrical properties, while also withstanding exposure to various solvents and chemicals. It bonds well to metals, glass, ceramics, and plastics.


2. Applications

  • Structural bonding for metals, ceramics, and plastics
  • Aerospace and automotive applications
  • Electronics assembly and encapsulation
  • High-performance industrial bonding
