LOCTITE EA 9390: Epoxy Adhesive Buying Guide for MRO
LOCTITE EA 9390 is an epoxy adhesive listed under part number LOCTITE EA 9390. For aircraft maintenance buyers, that identification is a starting point—not enough by itself to establish suitability for a particular repair. A useful purchase request pairs the exact part number with the application reference, required documentation, quantity, and packaging needs.
Key Takeaways
- CraftJetAero lists LOCTITE EA 9390 as an epoxy adhesive, with part number LOCTITE EA 9390.
- The part number identifies the requested product; it does not establish approval for a specific aircraft task.
- Ask for the current manufacturer data sheet before relying on handling or application details.
- Put document, quantity, packaging, and receiving requirements in the initial quote request.
What Does the LOCTITE EA 9390 Identifier Tell a Buyer?
The LOCTITE EA 9390 product listing identifies the item as an epoxy adhesive and gives its part number as LOCTITE EA 9390. Those are the product-specific facts established by the listing. It does not provide a manufacturer data sheet, technical properties, package configuration, or an aircraft application reference.
Keep the complete identifier on the requisition, request for quote, purchase order, and receiving record. An incomplete description such as “LOCTITE epoxy” may leave a supplier unable to determine which item the buyer intends. Conversely, adding an unverified suffix or package description can turn an otherwise clear request into a request for a different configuration.
A buyer can use the part number to begin a controlled document check: locate the applicable maintenance instruction, compare its specified material identification with the requested item, and obtain the current product documentation needed by the maintenance organization. If a work card names a different material, the shared description “epoxy adhesive” does not make the two items interchangeable. For broader context on this product family, see the aerospace epoxy adhesive selection guide.
How Should Engineers Evaluate It for a Maintenance Task?
Start with the job rather than a generic product description. Identify what is being joined, the substrates and surface condition, the joint geometry, the expected service environment, and any processing constraints at the work site. These details help the engineer determine which manufacturer documents and maintenance references are relevant; they should not be used to infer performance values that have not been verified.
For example, a request for an adhesive to bond a small bracket should state the exact aircraft task or drawing reference available to the maintenance team. It should not assume that every epoxy adhesive is appropriate for that bracket. A request involving a bonded panel may raise different questions about application method and joint preparation. Neither example establishes that LOCTITE EA 9390 is specified for that work.
Before use, verify the required material and any substitution or approval requirements against the applicable aircraft maintenance documentation and engineering instructions. Follow the current manufacturer data sheet for preparation, handling, application, and safety information; do not infer cure conditions, shelf life, or airworthiness eligibility from the product name or a supplier listing.
How Does an Epoxy Adhesive Differ From Related Materials?
Maintenance purchasing lists often group adhesives, sealants, and primers under aviation chemicals, yet the categories describe different functions. Knowing which function the task calls for helps buyers route questions to engineering and prevents a familiar product name from replacing the specified material. This comparison is about material categories, not a claim that LOCTITE EA 9390 performs every function shown.
| Material category | Primary purpose | Question for the buyer |
|---|---|---|
| Epoxy adhesive | Join surfaces through an adhesive bond | Which exact adhesive does the task identify? |
| Sealant | Seal a joint or gap against the conditions identified for the task | Is sealing, rather than bonding, the specified function? |
| Primer | Prepare a surface as part of a specified finishing or bonding process | Is a separate surface-treatment material called out? |
A joint can involve more than one material category, but one category should not be substituted for another merely because both are applied to a surface. If the work package calls for a sealant, consult the aircraft sealant types guide to frame the purchasing questions. If it calls for an adhesive, identify the adhesive by its specified product designation rather than by the broad word “epoxy.”
What Should Go in a LOCTITE EA 9390 Quote Request?
A good request makes the commercial requirement clear while separating it from technical decisions that belong to the maintenance or engineering team. State the exact requested identifier first. Then add the quantity and unit needed, any packaging requirement established by the job, the destination, and the documents your organization requires for review and receiving. If a packaging format is not known, ask what is offered rather than assuming a cartridge, kit, or other format.
For example, a buyer might write: “Please quote part number LOCTITE EA 9390, epoxy adhesive. Required quantity: [quantity and unit]. Please identify the offered packaging and provide the current manufacturer product data sheet and safety data sheet, along with the lot and date information available for the offered material. Advise if any detail of the requested item needs clarification.” The brackets prompt the buyer to fill in a real requirement; they are not a suggested order quantity.
Ask for documents by name if your receiving process depends on them. A data sheet addresses product instructions and characteristics, while a safety data sheet addresses hazard and handling information. Lot identification supports traceability of the material supplied. The exact records needed can differ by organization and task, so naming them in the request is more reliable than asking generally for “all paperwork.”
How Can Receiving Teams Prevent Identification Errors?
At receiving, compare the item supplied with the purchase order before the material enters the maintenance workflow. Check the product designation on the container or accompanying records, the quantity and package format, and the lot or date information required by the order. Resolve a mismatch through the organization’s established receiving process rather than silently changing the purchase record.
Keep related documents tied to the received lot or shipment under the organization’s document-control procedure. This matters when a technician later needs to connect the material at the work site with the material that procurement ordered. A clear chain of identifiers also makes questions easier to investigate: the buyer can refer to the purchase order, received package identification, and accompanying records without relying on memory or a shortened product name.
For repeat purchases, retain the exact part-number wording in the purchasing template, but review task-specific requirements each time. A previous purchase can help reconstruct what was ordered; it does not establish that the same material is appropriate for every future job.

Frequently Asked Questions
What is LOCTITE EA 9390?
LOCTITE EA 9390 is listed by CraftJetAero as an epoxy adhesive. Its listed part number is LOCTITE EA 9390.
Does the product listing establish an aircraft approval?
No. The listing identifies the product type and part number; it does not state an aircraft approval or identify an approved maintenance task.
What technical details should I request?
Request the current manufacturer product data sheet and safety data sheet, then identify any additional records your maintenance and receiving processes require. The listing alone does not state properties, processing conditions, or package details.
Is an epoxy adhesive the same as an aircraft sealant?
No. An adhesive is selected to join surfaces, while a sealant is selected to seal a joint or gap. The material specified for the task determines what to purchase.
How should I identify the item in a request for quote?
Use the complete part number, LOCTITE EA 9390, and describe it as an epoxy adhesive. Add your actual quantity and unit, plus any packaging and document requirements, so the supplier can respond to a defined request.
