LOCTITE EA 9395 AERO Epoxy Adhesive for Aerospace Composite Bonding and Fairing
LOCTITE EA 9395 AERO Epoxy Adhesive for High-Temperature Aerospace Bonding
LOCTITE EA 9395 AERO Epoxy Adhesive is a two-component structural paste developed for aerospace bonding, potting, filling, and fairing applications. The system cures at ambient temperature and maintains mechanical performance at temperatures reaching approximately 177°C. Its non-metallic filler makes it suitable for composite structures, while the thixotropic consistency helps the mixed adhesive remain in position on vertical, overhead, and irregular surfaces.
For aircraft manufacturing, composite repair, tooling, and assembly, LOCTITE EA 9395 AERO Epoxy Adhesive combines long working time, gap-filling capability, and elevated-temperature strength. The paste structure supports contour filling and surface fairing while giving operators time to position components before cure. Because final performance depends on preparation, geometry, cure schedule, and service conditions, users should qualify the adhesive on representative parts before production.
Key Benefits of LOCTITE EA 9395 AERO Epoxy Adhesive
LOCTITE EA 9395 AERO Epoxy Adhesive uses a Part A to Part B mixing ratio of 100:17 by weight. Volume measurement is not recommended for structural applications unless the process can maintain the correct ratio accurately. At 25°C, the mixed adhesive has a viscosity of approximately 100 to 300 Pa·s and a density near 1.31 g/ml. A 450 g mixed mass provides a pot life of about 95 to 100 minutes, supporting mixing, application, positioning, and tooling.
The cured adhesive provides performance across a wide temperature range. Published lap-shear data on 2024-T3 Alclad aluminum shows approximately 29.7 MPa at 25°C and about 8.3 MPa at 177°C after the specified room-temperature cure. Its stated service-temperature reference is approximately 177°C under the manufacturer’s test definition. The cured bulk material also offers good compressive strength for filling, fairing, and structural applications exposed to concentrated loads.
Applications for LOCTITE EA 9395 AERO Epoxy Adhesive
LOCTITE EA 9395 AERO Epoxy Adhesive is suitable for aerospace composite structures, bonded metal assemblies, honeycomb-related repairs, edge filling, void filling, potting, contour restoration, and surface fairing. Its non-metallic formulation is useful where metallic-filled materials are not preferred. It may also be considered for tooling, fixtures, transportation components, and industrial structures requiring a high-temperature epoxy paste.
The product should be selected after evaluating the substrate, surface treatment, bond-line thickness, environmental exposure, load direction, and inspection requirements. Adhesion and mechanical performance can vary on different composites, metals, primers, coatings, and surfaces. Representative testing and process approval are essential before aerospace production or critical repair work.
How to Apply LOCTITE EA 9395 AERO Epoxy Adhesive
Before applying LOCTITE EA 9395 AERO Epoxy Adhesive, ensure that all bonding surfaces are clean, dry, and properly prepared. Bring Part A and Part B close to room temperature, weigh them at the specified 100:17 ratio, and mix thoroughly until the color and consistency are uniform. Complete mixing is essential for reliable curing and final performance.
Apply the mixed paste within its working life and keep the bonded parts in firm contact while the adhesive sets. Handling strength is reached after approximately 24 hours at 25°C, although only limited loading should be applied then. Normal performance can be achieved by curing for five days at 25°C or for one hour at 66°C. Remove uncured excess adhesive before it hardens with an appropriate cleaner used according to its safety instructions.
Storage and Safety of LOCTITE EA 9395 AERO Epoxy Adhesive
Do not mix quantities greater than 450 g in one batch because the exothermic reaction can create dangerous heat buildup and uncontrolled decomposition. Use adequate ventilation, avoid skin and eye contact, and review the current safety data sheets for both components before handling. Store each component in its original closed container under recommended conditions.
