There are many reasons to choose a high-quality structural adhesive that can improve the production and performance of UAVs.
Structural adhesives are an excellent choice for applications requiring high durability, fatigue & environmental resistance, and the ability to distribute and absorb stress in challenging conditions.
ITW Performance Polymers offers a comprehensive range of Plexus® acrylic, hybrid, and polyurethane adhesives, along with Devcon® epoxies, metal repair putties for ceramic and metal, and military-approved silicones, delivering the right materials for all your structural bonding and reinforcement needs, such as:
UAV Structural Bonding Applications
| Application Area | Adhesive Type Suggested | Performance Requirements |
| Composite Bonding | Plexus Acrylic, Devcon Epoxy | High shear/peel strength, heat, fatigue, and environmental resistance. |
| Metal to Composite | Plexus Acrylic, Epoxy, PU | Dissimilar material compatibility, durability |
| Sensor Encapsulation | Insulcast® RTV Silicone, Epoxy | Vibration damping, electrical isolation, and environmental sealing |
| Panel Bonding | Plexus Acrylic, Devcon Epoxy | Large surface bonding, temperature stability |
The benefits of structural bonding versus mechanical fastening are well documented. Plexus methyl methacrylate structural adhesives represent significant weight-savings versus mechanical fastening, and allow for easier and more aerodynamic design.
Unlike mechanical fasteners, adhesives do not require creating holes in composite or metallic substrates that weaken the material’s structural integrity or concentrate stress at the joints. Adhesives are flexible and promote stress distribution, reducing fatigue by transferring force throughout the vehicle structure, relieving stress peaks that can damage assemblies. Stress distribution means designers can use lighter weight materials for the vehicle structure and panels, as well as dissimilar materials without fear of corrosion or stress issues.
Potting, Encapsulation, and Repair Solutions for UAV Systems
In addition to structural adhesives, ITW Performance Polymers also offers the Insulcast range of epoxy and silicone potting and encapsulating materials for electrical isolation and protection of electrical and electronic components. These materials are ideal for helping shield sensitive UAV systems from vibration, moisture, contaminants, and environmental exposure.
ITW Performance Polymers also provides several Mil-Spec approved metal and ceramic repair putties and silicones for maintenance, repair, and specialty performance applications.
