Common Bonding and Adhesive Assembly Areas

  • Shop worker in PPE applying 3M™ Impact Resistant Structural Adhesive (IRSA).
    Exterior Attaching and Bonding

    3M tapes and adhesives are ideal replacing welds and mechanical fasteners potentially making your process more efficient through elimination of drilling, grinding, refinishing, screwing, welding and clean-up.

    Typical Applications:

    • Exterior side panel assembly
    • Attaching trims, fixtures and accessories
    • Roof panel attachment
  • Worker applying 3M™ extreme sealing tape to a metal exterior.
    Exterior Sealing

    3M adhesive sealants and extreme sealing tapes are ideal for vertical and horizontal joint sealing resulting in improved process efficiencies without having to compromise on design freedom.

    Typical applications:

    • Exterior side panel sealing
    • Glass and mirror sealing
    • Roof assembly
  • 3M™ extreme sealing tape being applied to an interior vertical joint.
    Interior Assembly

    3M tapes and adhesives quickly and easily create a long-lasting bond that can actually build strength over time. With the ability to join a variety of materials including aluminum, steel, glass, plastics and painted and powder-coated surfaces, they provide resilient bonding solutions to virtually any surface.

    Typical applications:

    • Wall and door panel attachment
    • Headliners and ceiling systems
    • Floor systems
    • Insulation attachment
    • Wiring and cable harnessing
    • Mirrors and fixtures

    Featured Applications

    3M tapes and adhesives are ideal replacing welds and mechanical fasteners potentially making your process more efficient through elimination of drilling, grinding, refinishing, screwing, welding and clean-up.

    • 3M™ Nitrile Industrial Adhesive 4491 is a sprayable, fast-drying adhesive that provides strong, flexible bonds with excellent environmental resistance. In addition, our 3M™ Nitrile Industrial Adhesive 4491 has the ability to be heat cured to obtain superior physical properties.

    • We designed 3M™ Hi-Strength Postforming Adhesive 94 CA to have an aggressive tack that offers a high initial grab as well as sufficient open time to position materials properly. High-solids content supports its low soak-in property, giving you ample time to align your insulation properly. This attribute also provides higher coverage than competing adhesives, alongside its 15-minute bonding range.

    • 3M™ Extreme Sealing Tape 4411N is a translucent, highly conformable, single-sided, pressure sensitive acrylic adhesive tape with a high performance ionomer backing. It is an ideal solution for creating a water tight seal. It conforms over fasteners, seams, joints, holes and gaps to ensure a long-lasting seal on a variety of substrates.

    • 3M™ Polyurethane Sealant 540 is a single-component, moisture-curing, polyurethane sealant used to bond a wide variety of materials, including plastics, fiberglass reinforced plastic (FRP), sheet molding compound (SMC), aluminum, steel, coated metal and wood.

    • Offers excellent UV resistance and long term durability when exposed to the elements. This sealant is permanently elastic and is capable of bonding dissimilar materials, offering long-lasting bonds and design flexibility. This single-component sealant is paintable when wet and has a 40-60 minute skin time.
