LOCTITE EA 9460 High-Strength Structural Epoxy Adhesive for Metal, Plastic and Composite Bonding

LOCTITE EA 9460 Epoxy Adhesive Benefits

LOCTITE EA 9460 Epoxy Adhesive is designed for users who need strong structural performance. The resin and hardener mix at 1:1 by volume and 1:1 by weight, helping reduce proportioning errors. The white resin and black hardener form a uniform gray mixture, providing a visual indication that both components have been blended thoroughly.

The non-sag formula maintains bead shape on horizontal, vertical, and irregular surfaces. Its pot life of approximately 40 to 65 minutes at 25°C gives operators time to dispense, position, align, and fixture assemblies. The cured adhesive also resists automotive fluids, making it useful for transportation, machinery, equipment, and industrial maintenance applications.

Applications for LOCTITE EA 9460 Epoxy Adhesive

This structural epoxy is recommended for bonding dissimilar substrates, including metals, engineering thermoplastics, and thermoset laminates such as sheet molding compound. Typical uses include metal frames, brackets, panels, housings, machine components, transportation assemblies, appliance parts, and composite structures. Its combination of peel strength, shear strength, impact resistance, and fatigue resistance supports joints exposed to vibration and changing mechanical loads.

The adhesive can be used where rigid fastening methods may concentrate stress or require drilling and hardware. Because plastics, coatings, surface treatments, and composite formulations vary, manufacturers should test the materials and joint design before production. Bond-line thickness, surface preparation, cure temperature, and service exposure influence final performance.

LOCTITE EA 9460 Epoxy Adhesive Technical Performance

The mixed product has a typical specific gravity of approximately 1.33 and viscosity of about 150,000 to 250,000 mPa·s at 25°C. Published cured properties include Shore D hardness of at least 75, tensile strength of approximately 30.3 N/mm², elongation of about 3.5%, and a glass transition temperature near 68°C under stated test conditions.

On etched aluminum with a 0.125 mm gap, Henkel reports lap-shear strength of approximately 24.1 N/mm² at 25°C after curing. The adhesive also maintains useful strength across wider bond gaps and at elevated or reduced temperatures. These values are typical laboratory data rather than guaranteed specifications, so production qualification remains essential.

How to Apply LOCTITE EA 9460 Epoxy Adhesive

Clean each bonding surface and remove oil, grease, dust, oxidation, moisture, and loose contamination. Dispense equal quantities of resin and hardener, then mix until the color is uniform. When using a dual cartridge, confirm both components flow evenly, attach the correct static mixer, and discard the initial material before applying the adhesive.

Apply the mixed epoxy to one or both surfaces, assemble the parts within the working time, and hold them securely while curing. Complete room-temperature cure is achieved in approximately 72 hours at 25°C, with about 90% of final properties developing after 24 hours. Validated heat curing can shorten the process. Remove excess uncured adhesive before it hardens.
