Product Description
LOCTITE EA 9396.6MD is an easy-mixing, two-part syntactic epoxy adhesive developed for potting and edge-fill applications. It combines a low mixed density of 0.63 g/mL with a 100:31 resin-to-hardener mix ratio by weight and a 120-minute pot life for a 100 g mass at 25 degrees C. The system cures for 5 days at 25 degrees C or 60 minutes at 82 degrees C. Typical cured data include 44.8 MPa ultimate compressive strength at 25 degrees C and 26.9 MPa at 149 degrees C, plus lap shear strength of 18.6 MPa at 25 degrees C and 9.7 MPa at 149 degrees C on prepared 2024-T3 aluminum under the documented test configuration. The documented service temperature is 149 degrees C.

Additional Information
LOCTITE EA 9396.6MD
LOCTITE EA 9396.6MD is a two-part syntactic epoxy adhesive for potting and edge-fill applications. The light-blue mixed material has a typical density of 0.63 g/mL, a 120-minute pot life for a 100 g mass at 25 degrees C, and ambient or accelerated cure options. Published data show compressive and lap-shear strength retention at 149 degrees C, together with X-band dielectric properties.

As-supplied properties
Values are source-reported and typical where indicated. Preserve component identity, ratio basis, mixed mass, temperature and test context during process evaluation.
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Product form | Two-part syntactic epoxy adhesive | N/A | Resin and hardener require mixing before application. |
| Part A appearance | Light blue | N/A | As-supplied resin. |
| Part B appearance | White | N/A | As-supplied hardener. |
| Mixed appearance | Light blue | N/A | After complete mixing. |
| Mix ratio | 100:31 | By weight | Resin to hardener. |
| Part A density | 0.72 | Unit not stated | The TDS reports the numerical density without an explicit unit. |
| Part B density | 0.5 | g/mL | As-supplied hardener. |
| Mixed density | 0.63 | g/mL | Mixed adhesive. |
| Pot life | 120 | Minutes | 100 g mixed mass at 25 degrees C in a water bath; ASTM D2471. |
Mixing, application, and cure
Control component temperature, the weight ratio, mixed mass, surface preparation, assembly support and cure schedule. Pot life is reported for a 100 g mass, while the supplier separately limits batch size to 450 g because larger masses can generate hazardous exotherm.
Store in unopened containers in a dry location and do not return dispensed material to the original container. The TDS states a 12-month shelf life at or below -18 degrees C in original unopened containers; component data also list Part A at 365 days at 4 degrees C or -18 degrees C, and Part B at 365 days at 4 degrees C or 180 days at or below 28 degrees C. Review the current container label and SDS before handling. Part A is classified for skin and eye irritation and skin sensitization; Part B is classified for severe skin burns and eye damage and skin sensitization. Use adequate ventilation and the protective equipment required for the task.
