LOCTITE E-60HP

Main features

  • Extended 60-Minute Working Life
  • Toughened Structural Epoxy Bonding
  • Electrical-Insulating Cured Bondline

Product Description

LOCTITE EA E-60HP is a two-part, toughened structural epoxy adhesive with medium viscosity, extended working life and room-temperature cure. The resin and hardener mix 2:1 by volume and provide a 60-minute working life at 23 deg C, supporting assembly adjustment before cure. After a five-day cure at 23 deg C, the adhesive develops high lap-shear strength on prepared metal substrates together with electrical-insulating and mechanical properties. It is intended for high-performance structural bonding across supported engineering substrates where a longer processing window is more important than rapid fixture.

Key features

  • Extended work life: Provides a 60-minute working life at 23 deg C for assembly adjustment before cure.
  • Toughened room-temperature cure: Two-part medium-viscosity epoxy cures at room temperature to a tough off-white bondline.
  • Steel and Aluminum Bond Strength: Typical lap shear strength is 30 N/mm^2 under ISO 4587 on grit-blasted mild steel and acid-etched, abraded aluminum after a five-day cure at 23 deg C.

Applications

Structural bonding applications requiring high performance and extended work life across supported engineering substrates.

Specific Gravity
Specific gravity (SG) is the ratio of the density of a substance to the density of a reference substance; equivalently, it is the ratio of the mass of a substance to the mass of a reference substance for the same given volume. For liquids, the reference substance is almost always water (1), while for gases, it is air (1.18) at room temperature. Specific gravity is unitless.

Physical Properties
Viscosity
Viscosity is a measurement of a fluid’s resistance to flow. Viscosity is commonly measured in centiPoise (cP). One cP is defined as the viscosity of water and all other viscosities are derived from this base. MPa is another common unit with a 1:1 conversion to cP. A product like honey would have a much higher viscosity -around 10,000 cPs- compared to water. As a result, honey would flow much slower out of a tipped glass than water would. The viscosity of a material can be decreased with an increase in temperature in order to better suit an application
