Main features

  • One-Component, No-Mix Epoxy Paste Simplifies Material Preparation
  • 37 N/mm^2 Stainless-Steel Lap Shear
  • 22 kV/mm Dielectric Strength

Product Description

LOCTITE EA E-214HP is a one-component, no-mix, heat-activated epoxy adhesive supplied as a light grey thixotropic paste. It is designed to form tough structural bonds on prepared metals, glass, ceramics, selected plastics, and wood. The cured adhesive combines strong substrate-specific shear performance with a glass transition temperature of 120 degrees C, Shore D hardness of 85, and dielectric breakdown strength of 22 kV/mm. Its thixotropic rheology supports controlled placement, while the documented cure and bondline guidance helps users evaluate it for assemblies that can accommodate a heat-cure process.

Key features

  • One-component heat-cure epoxy: Requires no mixing before application.
  • Thixotropic light grey paste: Supports controlled adhesive placement and bondline management.
  • Prepared-metal lap shear: Typical values include 37 N/mm2 on stainless steel and 33 N/mm2 on grit-blasted steel after the stated cure.
  • Cured thermal and electrical properties: Typical glass transition temperature is 120 degrees C and dielectric breakdown strength is 22 kV/mm.
  • Documented environmental resistance: Retained-strength data are available for heat, fluids, solvents, humidity, water, and salt-fog exposure under defined test conditions.

Applications / Suitable for

  • Prepared steel, stainless steel, and aluminum bonding
  • Glass and ceramic bonding
  • Selected plastic bonding, including polycarbonate, nylon, PVC, and acrylic, subject to application testing
  • Wood bonding where the assembly can accommodate the required heat-cure process

Preparation, assembly, and heat cure

Processing and application

Bond performance depends on clean surfaces, even adhesive coverage, controlled assembly, and a complete heat-cure cycle. Keep parts from moving while the adhesive cures.

Surface preparation: Remove paint, oxide films, oils, dust, mold-release agents, and other contaminants from the bonding surfaces.
Application and assembly: Apply adhesive evenly to both surfaces, join the coated parts, maintain contact pressure, and prevent movement during cure.
Heat cure and bondline: Cure at 120 degrees C or above until completely firm. Heating at 150 degrees C for 2 hours is identified for maximizing properties. Maximum shear strength was obtained with a 0.08 to 0.13 mm bondline.
Storage and Handling

Store at or below 4 degrees C in the original, tightly closed container in a cool, dry, well-ventilated location away from heat, sparks, flame, direct sunlight, and incompatible materials. Do not return removed material to the original container. Use adequate ventilation and appropriate protective gloves, clothing, and eye and face protection. Do not use solvents to clean hands. Uncured excess may be removed with a ketone-type solvent using appropriate controls. Heating may cause a fire, and storage above 4 degrees C can adversely affect product properties. Avoid sections greater than 6 mm because exothermic heat buildup can cause rapid expansion, blistering, or cracking. Do not use the product in pure oxygen or oxygen-rich systems, and do not select it as a sealant for chlorine or other strong oxidizing materials.

Bonding and environmental performance

The following values are typical laboratory results for the specified substrates, surface preparations, cure schedules, bondlines, and exposure conditions. They should be used for product evaluation rather than as guaranteed design allowables.

Substrate-specific shear strength
Lap shear: grit-blasted steel, 33 N/mm2; acid-etched and abraded aluminum, at least 13.8 N/mm2; anodized aluminum, 8.4 N/mm2; stainless steel, 37 N/mm2; polycarbonate, 10 N/mm2; nylon, 1.2 N/mm2; and fir wood, 5 N/mm2. Block shear, ISO 13445: epoxy, 9.2 N/mm2; glass, 23 N/mm2; PVC, 5.2 N/mm2; and acrylic, 3.7 N/mm2.
Cure condition: 2 hours at 120 degrees C followed by 4 hours at 22 degrees C. Lap-shear specimens used a zero-gap condition. Results are specific to the stated substrate and surface preparation.
Chemical and environmental retained strength
Retained strength after 500 and 1,000 hours, respectively: air at 87 degrees C, 90% and 80%; 10W30 motor oil at 87 degrees C, 95% and 95%; unleaded gasoline at 87 degrees C, 110% and 115%; 50/50 water-glycol at 87 degrees C, 85% and 80%; water at 22 degrees C, 70% and 70%; acetone at 22 degrees C, 110% and 100%; isopropanol at 22 degrees C, 120% and 115%; salt fog at 22 degrees C, 45% and 60%; condensing humidity at 49 degrees C, 60% and 50%; and 95% relative humidity at 40 degrees C, 75% and 70%.
Acid-etched and abraded aluminum lap shear; cure of 2 hours at 120 degrees C followed by 4 hours at 22 degrees C; 0.12 to 0.23 mm gap; tested at 22 degrees C after exposure.
Temperature-dependent strength profile
Hot-strength testing shows retained room-temperature strength decreasing as the test temperature rises, with the plotted curve reaching approximately 50% at 150 degrees C. Separate heat-aging curves document condition-dependent retained strength after exposure for up to 1,000 hours at 65, 93, 120, 150, and 175 degrees C.
Heat-aging specimens were steel with no induced gap, cured for 2 hours at 120 degrees C and 4 hours at 22 degrees C, then tested at 22 degrees C. The graphical data are approximate and configuration-specific.
Supported bonding contexts

Applications and substrate evaluation

The product is documented for bonding metals, glass, ceramics, plastics, and wood. Strength depends on substrate grade, surface preparation, joint geometry, bondline, and cure, so representative application testing remains important.
