This two-part epoxy system is widely used for metal bonding, honeycomb structure repair, component potting, and sealing applications in aircraft manufacturing and maintenance. Its balanced formulation allows precise application, controlled curing, and consistent bonding quality across different substrates. The adhesive complies with recognized aerospace material standards and is trusted by manufacturers, maintenance providers, and engineering teams worldwide.
By combining mechanical strength, environmental resistance, and ease of use, this aerospace epoxy adhesive supports both production assembly and on-site repair tasks. It is suitable for operations that require predictable performance, controlled costs, and compliance with international quality systems.
Core Features
High Temperature Resistance for Aerospace Environments
This epoxy adhesive maintains stable bonding performance under elevated temperatures commonly found in aerospace environments. It resists thermal degradation and softening, ensuring that bonded joints remain secure during continuous operation, heat cycling, and exposure to localized high-temperature zones. This feature makes it suitable for aircraft structural components, engine-adjacent assemblies, and high-altitude applications.
Room-Temperature Curing Without Complex Equipment
The adhesive supports reliable curing at room temperature, eliminating the need for ovens or heat-assisted curing equipment in most applications. This simplifies installation, reduces energy consumption, and allows efficient use in workshops, hangars, and field repair environments. For projects requiring faster turnaround, controlled heat can be applied to accelerate curing while maintaining bond integrity.
Resistance to Moisture and Thermal Cycling
Moisture exposure and repeated temperature changes are common causes of adhesive failure. This aerospace epoxy adhesive is designed to resist moisture ingress and thermal fatigue. It maintains bonding stability under humid conditions and during repeated heating and cooling cycles, reducing the risk of cracking, delamination, or bond weakening over time.
Compliance with Aerospace Material Standards
The product meets established aerospace material specifications, including recognized military and OEM standards. Compliance ensures consistent quality, traceability, and compatibility with aerospace manufacturing and maintenance procedures. Its controlled viscosity and thixotropic behavior prevent sagging or dripping, enabling accurate application on vertical or inclined surfaces.
Low Toxicity and Safe Handling Characteristics
Worker safety is a key consideration in aerospace production environments. This epoxy adhesive is formulated with low toxicity to reduce health risks during handling and application. It supports safe use in enclosed facilities when standard protective measures are followed, contributing to a safer working environment without compromising performance.
Typical Uses
Structural Metal Bonding in Aircraft Assembly
The adhesive is commonly used to bond aerospace metals such as aluminum alloys, stainless steel, and titanium. It provides strong, durable joints capable of withstanding mechanical stress, vibration, and pressure changes during flight operations. Applications include brackets, panels, reinforcements, and secondary structural components.
Honeycomb Core and Sandwich Panel Repair
Honeycomb structures are widely used in aircraft interiors and lightweight structural panels. This epoxy adhesive effectively bonds and repairs honeycomb cores without adding excessive weight. It fills gaps, restores mechanical integrity, and supports long-term performance, making it suitable for both production bonding and maintenance repairs.
Component Potting and Encapsulation
The adhesive is suitable for potting and encapsulating electronic components, sensors, and wiring assemblies used in aerospace systems. It provides environmental protection against moisture, dust, and temperature variation, helping maintain consistent electrical performance and extending component service life.
Liquid Gasket and Sealing Applications
In specific aerospace assemblies, the epoxy adhesive can function as a liquid gasket. It creates a continuous, leak-resistant seal between mating surfaces, reducing the risk of fluid leakage and eliminating issues associated with traditional gasket materials such as compression loss or aging.
Precautions
Storage Conditions
Store the adhesive components in a cool, dry environment away from direct sunlight and heat sources. Proper storage helps maintain shelf life and ensures consistent curing behavior.
Mixing Accuracy
As a two-component epoxy system, accurate mixing of Part A and Part B is essential. Follow the manufacturer’s recommended mixing ratio and procedure to achieve optimal mechanical strength and curing performance.
Application Safety
Use appropriate personal protective equipment, including gloves and safety glasses, during handling and application. Avoid prolonged skin contact and ensure adequate ventilation in enclosed work areas.
Curing Environment
Maintain stable ambient temperature and humidity during curing. Extreme environmental fluctuations may affect curing time and final bond properties.
Waste Disposal
Dispose of unused material and packaging in accordance with local environmental regulations. Proper disposal reduces environmental impact and ensures regulatory compliance.
