LOCTITE® EA E-20HP Structural Adhesive
Features and Benefits
This high impact-strength adhesive is toughened to meet demanding and versatile applications, including metal-to-metal and magnet bonding.
LOCTITE® EA E-20HP is a 2-part, high impact- and humidity-resistant structural bonder. Once mixed, it cures at room temperature to form a tough bondline with high peel resistance. It has a very high shear strength of 33 N/mm², is resistant to a wide range of chemicals and solvents, and withstands temperatures up to 150°C (302°F). Ideal for metal-to-metal bonding, it can also be used as a magnet bonder for surface and interior permanent magnets (SPM & IPM), and is an excellent electrical insulator. Bonds a wide variety of plastics, metals, dry concrete and architectural materials. Typical applications include marine in-line shaft generators.
