Loctite EA E-20HP Epoxy Adhesive Overview

Loctite EA E-20HP is a toughened, medium-viscosity, industrial-grade epoxy adhesive designed for high-performance bonding across a variety of substrates. With a medium working life of 20 minutes, this two-part epoxy cures at room temperature to form a tough, off-white bond line with high peel resistance and excellent shear strength. Once fully cured, Loctite E-20HP offers outstanding resistance to impact, humidity, chemicals, and solvents, making it suitable for general-purpose industrial applications. It bonds well to plastics, metals, dry concrete, and architectural materials, providing strong and durable bonds.

Loctite EA E-20HP is ideal for demanding environments, with temperature resistance up to 150°C (302°F), and acts as an excellent electrical insulator, making it versatile for a range of applications, including magnet bonding and metal-to-metal assemblies.
