LOCTITE EA 9396C-2
Harmonization Code : 8529.90 | Parts solely or principally used for TV, radio, and transmission
Main features
- Extended Processing Window
- 1-Hour Cure Cycle
- Non-MDA Curing and Application
Product Description
LOCTITE EA 9396C-2 AERO is a two-part, elevated-temperature-curing epoxy paste adhesive for structural bonding and neat lay-up resin use. The system combines a blue Part A with a purple Part B to form a violet mixed adhesive at a 100:36 weight ratio. It provides a 7-hour pot life for a 450 g mass at 25 degrees C and requires a minimum cure of 1 hour at 93 degrees C. On phosphoric-acid-anodized 2024-T3 aluminum, typical tensile lap shear strength is 31.7 MPa at 25 degrees C and 17.2 MPa at 177 degrees C after the stated cure.
Key features
- Extended pot life: 7 hours at 25 degrees C for a 450 g mixed mass, supporting a controlled working window.
- Temperature-dependent bond performance: Typical lap shear is 31.7 MPa at 25 degrees C and 17.2 MPa at 177 degrees C on the documented aluminum test configuration.
- Non-MDA curing system: Uses a non-aromatic amine curing agent and is identified for use as a neat lay-up resin.
Applications / Suitable for
- Neat lay-up resin use.

| Pot life | 7 | hours | Typical value for a 450 g mixed mass at 25 degrees C; ASTM D2471 in a water bath. |
| Color | Blue; purple; violet | - | Part A; Part B; mixed adhesive, respectively. |
| Viscosity, Part A | 70 | Pa s | At 25 degrees C; Brookfield HBT spindle 4 at 1.05 rad/s. |
| Viscosity, Part B | 0.04 | Pa s | At 25 degrees C; Brookfield LVF spindle 1 at 3.17 rad/s. |
| Density, Part A / Part B / mixed | 1.17 / 1.00 / 1.15 | g/mL | As supplied for Parts A and B; mixed state for the combined adhesive. |

Mix, apply and cure under controlled conditions
Complete mixing, controlled batch size, prepared bonding surfaces and the specified heat cure are central to obtaining the documented performance. Keep the separate components near room temperature before mixing and maintain contact between the parts until the adhesive is set.
Shelf life is 1 year for both Part A and Part B when stored below 4 degrees C or below 25 degrees C. Material may be shipped at ambient conditions when it is placed into its intended storage upon receipt. Keep containers tightly closed in a cool, well-ventilated area. Do not heat unmixed Part A above 80 degrees C. For industrial use only; follow the current product label and safety data sheet, use adequate ventilation and wear appropriate personal protective equipment.
