LOCTITE EA E-310

Main features

  • Glass, Metal, and Plastic Bonding
  • 6,000 psi Shear Strength
  • Up to 5.1 mm Gap Filling

Product Description

LOCTITE® EA E-310 is a single-component epoxy adhesive for structural bonding of metal, glass, and plastic. The silver-gray material cures at elevated temperatures and has a typical viscosity of 400,000 mPa·s at 25°C, supporting controlled placement and gap filling up to 5.1 mm (0.2 in). The cured adhesive is characterized by vibration and impact resistance, with typical lap shear strength reaching 6,000 psi (41 MPa) on steel under ASTM D1002 testing. Its documented operating-temperature range is -85°C to 204°C (-65°F to 400°F), making it suitable for evaluation in bonded assemblies exposed to a broad range of service temperatures.

Key features

  • Single-component heat-cure epoxy: Eliminates component mixing and cures in 12 to 45 minutes at documented temperatures from 150°C to 200°C.
  • Structural bonding performance: Provides typical ASTM D1002 lap shear strength of 6,000 psi (41 MPa) on steel and 5,800 psi (40 MPa) on aluminum.
  • Gap-filling consistency: The 400,000 mPa·s viscosity at 25°C and maximum documented gap of 5.1 mm support thicker adhesive sections.

Applications / Suitable for

  • Structural bonding of metal substrates
  • Structural bonding of glass
  • Structural bonding of plastic 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

Thermal Properties
Flash Point
The flashpoint of a solvent is the lowest possible temperature at which it can vaporize to form an ignitable vapor. Flashpoint is often confused with “autoignition temperature”, which is the temperature at which a solvent ignites without an ignition source.
