Product Description
LOCTITE EA 9359.3 AERO is a two-component structural epoxy paste adhesive with non-sag handling, integrated 0.13 mm glass beads for bondline thickness control, and a 2:1 dual-cartridge format with static mixer. The yellow Part A and blue Part B form a green mixed adhesive with a typical density of 1.12 g/mL. Pot life is mass-dependent at 25°C, ranging from 60 minutes for 100 g to 40 minutes for 450 g. The adhesive cures at room temperature or with an accelerated 1-hour cure at 82°C for small mixed quantities. Typical testing on phosphoric-acid-anodized 2024-T3 AlClad aluminum demonstrates tensile lap shear and T-peel performance, while the cured adhesive provides resistance to water, salt spray, and most organic fluids.
Key features
- Controlled bondline thickness: Integrated 5 mil/0.13 mm glass beads help establish a defined adhesive layer.
- Non-sag cartridge application: Supplied in a 2:1 dual cartridge with static mixer for controlled two-component dispensing.
- Mass-dependent working window: Typical pot life at 25°C is 60 minutes for 100 g, 50 minutes for 200 g, and 40 minutes for 450 g.
- Room-temperature or accelerated cure: Normal performance develops after 5–7 days at 25°C; a 1-hour cure at 82°C may be used for small mixed quantities.
- Prepared-aluminum bond performance: Typical results at 25°C include 31.0 MPa tensile lap shear and 267 N/25 mm T-peel under the stated test conditions.
Suitable for
- Structural bonding applications involving metals.
- Bonding applications involving thermoplastics.
- Bonding applications involving composite substrates.

Additional Information
LOCTITE EA 9359.3 AERO
LOCTITE EA 9359.3 AERO is a two-component structural epoxy paste adhesive with integrated 0.13 mm glass beads for bondline control. The non-sag system is supplied in a 2:1 dual cartridge with static mixer and develops typical prepared-aluminum lap shear and T-peel performance after room-temperature cure. The cured adhesive also provides resistance to water, salt spray, and most organic fluids.
As-Supplied Properties
Values apply to the separate components or freshly mixed adhesive as identified. Viscosity values retain the stated instrument, spindle, speed, and temperature.
| Property | Value | Unit / state | Method / condition |

Processing and Cure
Control the component ratio, mixed mass, surface condition, assembly support, and cure schedule. The exotherm increases with mixed quantity, so batch size is a safety-critical processing parameter.
Keep the components tightly closed in their original containers in a cool, well-ventilated area away from heat, sparks, flame, and incompatible materials. Shelf life is 1 year at 25°C for Part A and Part B; store Part A at or below 25°C. Avoid mixing the components until the adhesive will be used immediately. For industrial use only; follow the current product-label and safety instructions for both components before handling.
