Product Description
LOCTITE EA 960F is a two-part, rapid room-temperature-curing epoxy fairing and smoothing compound for exterior aircraft surfaces. The paste system is color coded: reddish brown Part A and off-white Part B mix to a uniform red, providing a visual indication of complete mixing. A 100:50 Part A-to-Part B mix ratio by weight is paired with a 30-minute pot life for a 100 g mass at 25 degrees C. Handling strength develops in 1 hour at 25 degrees C, and the cured compound may be sanded or painted after 5 hours at that temperature. Typical lap shear strength is 15.2 MPa at 25 degrees C on prepared 2024-T3 bare aluminum after a 24-hour cure.
Key features
- Product form: Two-part epoxy paste fairing and smoothing compound.

Additional Information
LOCTITE EA 960F
LOCTITE EA 960F is a two-part epoxy paste developed for fairing and smoothing exterior aircraft surfaces. The fast room-temperature-curing compound combines filler capability with a red color-change mixing indication, 30-minute pot life for a 100 g mass at 25 degrees C, and a cured surface that can be sanded or painted after 5 hours at that temperature.
As-supplied properties
Component identity, temperature, method, ratio basis, and mixed mass are important when interpreting these source-reported values.
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Product form | Two-part epoxy paste | N/A | Fairing and smoothing compound for exterior aircraft surfaces. |
| Part A color | Reddish brown | N/A | As supplied. |
| Part B color | Off white | N/A | As supplied. |
| Mixed color | Red | N/A | After thorough mixing; used as a visual indication of complete mixing. |
| Part A viscosity | 6500 / 650 | Poise / Pa s | At 25 degrees C; Brookfield HBT, spindle 7 at 20 rpm or 2.09 rad/sec. |
| Part B viscosity | 600 / 60 | Poise / Pa s | At 25 degrees C; Brookfield HBT, spindle 6 at 20 rpm or 2.09 rad/sec. |
| Mix ratio | 100:50 | By weight | Part A to Part B. |
| Mix ratio | 3:2 | By volume | Part A to Part B. Volume measurement is not recommended for structural applications unless special precautions assure the correct ratio. |
| Pot life | 30 | Minutes | 100 g mixed mass at 25 degrees C; ASTM D2471. |
| Warranty life | 1 year below 4 degrees C; 1 year below 25 degrees C; 6 months below 32 degrees C | N/A | Reported for both Part A and Part B. |
Mixing, application, and cure
Bring both components close to room temperature, combine them at the documented ratio, and mix until the entire material is uniformly red. Apply only to clean, dry, properly prepared surfaces. Heat buildup during and after mixing is normal; do not mix quantities greater than 250 g because uncontrolled decomposition and toxic fumes can occur.
Warranty life is reported for both components as 1 year when stored below 25 degrees C and 6 months when stored below 32 degrees C; one year is also reported below 4 degrees C. Store Part A between 0 and 25 degrees C and keep containers tightly closed. Store Part B in its original container in a cool, well-ventilated area away from heat, sparks, and open flame. Follow current container labels and safety documentation.
Final properties
Mechanical values are typical test results for the documented substrate, preparation, cure, and temperature. They are not universal joint design allowables.
| Property | Value | Unit | Method / condition |
|---|---|---|---|
| Cured density | 1.37 | g/cm3 | Cured material. |
| Typical tensile lap shear strength | 2200 / 15.2 | psi / MPa | ASTM D1002 at 25 degrees C after 24 hours at 25 degrees C; 2024-T3 bare aluminum, FPL etched per ASTM D2651-90. |
| Service temperature | 160 / 71 | degrees F / degrees C | Defined as the temperature at which the adhesive retains 1000 psi or 6.9 MPa using ASTM D1002. |
