    3M™ Thermoplastic Bonding

    For bonding challenging materials together, this is a game changer. It’s perfect for glass-phenolic composites and thermoplastic materials, including Polycarbonate (PC), Polyphenyl Sulfone (PPSU), Polyether Imide (PEI) and Acrylic-PVC. Use on tray tables, seat back covers, international first-class surrounds and more.
     

    • Designed for interior substrates, such as glass-phenolic composites, aluminum and hard-to-bond thermoplastics
    • Can be used on metal and composite surfaces
    • Very low sag formulation delivers controlled flow for vertical applications
    • FST compliant

Fewer steps, increased productivity.

  • Fastener demonstrating ideal application on bonding fasteners, brackets and pins

    3M™ Bracket Bonding

    There are thousands of brackets in each airplane. Imagine how much time and money you’ll save with a faster, simplified process. Now imagine a revolutionary bracket adhesive that instantly holds — with no installation fixtures, no sag and no mess. Simply apply, bond and go.
     

    • 3M™ Bracket Bonding is ideal for bonding fasteners, brackets and pins.
    • High green strength significantly reduces the need for installation fixtures
    • Two steps — apply and bond — simplifies your process
    • Low-flow adhesive can be used in vertical and overhead applications

    3M™ Potting Compounds

    Need to cut weight from a ship-set? Apply 3M potting compounds, designed with high shear and torque strength, class-leading low density, easy flow for easy application and fast cure times. Our 3M glass bubble technology reduces weight, delivers high strength-to-weight ratio and has a consistent fast flow through dispensers. Easy-to-handle viscosity and fully pumpable systems save time and improve operational efficiency.
     

    • Attach panel inserts quickly, consistently and securely
    • Low viscosity enables extruding and pumping with automated dispensing equipment
    • Fast cure at room temperature yields higher manufacturing throughput
    • Advanced formulation results in consistent density during both storage and automated pumping

    3M™ Honeycomb Bonding

    There can be no compromise when it comes to reliability. 3M honeycomb bonding solutions stand up to challenging conditions and offer operational flexibility, with work lives as short as 4 minutes or as long as 5 hours. Superior mechanical properties allow you to achieve high durability and light-weighting goals. These proven adhesives answer the demand for strength while enabling more compact and lightweight designs.
     

    • Maximum shear, compressive and peel strength, based on your design and process parameters
    • Fast to moderate handling strength time offers operational flexibility
    • Highly durable to help provide high impact resistance
    • Cure at room temperature
    • Thixotropic properties offer controlled flow and sag
    • FR and FST options
