Fast, easy adhesion with excellent bonding strength

  • When your project requires reliable long-term bonding of dissimilar substrates, 3M™ Scotch-Weld™ Structural Acrylic Adhesives significantly improve throughput and productivity. These adhesives can withstand extreme temperatures, build strength rapidly and resist impact and peel.

    Created for designers, engineers and manufacturers who need efficient bonding and greater design flexibility, 3M™ Scotch-Weld™ Structural Acrylic Adhesives are suitable for bonding most plastics, aluminum, steel and oily metal surfaces. Fast and easy to apply, our acrylic adhesives provide bonds that replace metal fasteners for both static and dynamic loads and enable improved aesthetics.

    3M™ Scotch-Weld™ Structural Acrylic Adhesives also offer low-odor and non-flammable formulations to help where odors can be annoying or where flammability is a concern.


  • Discover the Important Attributes of Acrylic Adhesives

    Hotspot selector of Acrylic attributes

Strength

Acrylics are nearly as strong as epoxies, with a chemistry that can be modified to provide both high peel and shear strength

Bonding

Acrylics adhere to a wide variety of materials, including many plastics

Process Efficiency

Acrylics have faster cure speeds and higher tolerance for unprepared surfaces than epoxies or urethanes

Impact Resistance

Depending on the chemistry, structural adhesive bonds provide the strength or flexibility to resist shock, vibration and impact loads

Lightweighting

Adhering to new materials and distributing stress along the entire bond area helps designers use thinner and lighter materials

NVH

Stiff bonds resist vibration and reduce opportunities for loose parts to make unwanted noise

Aesthetics

Structural adhesives provide better product appearance through invisible joints and smooth bond lines

Water Intrusion

Structural adhesives provide a continuous bond line to prevent the migration of fluids, dust and dirt

Innovation in Design

The ability of structural adhesives to bond a wide variety of substrates allows the freedom to design for the best materials available

Benefits, Applications and Products of Acrylic Adhesives

  • This white paper discusses wet-out and why LSE surfaces are difficult to bond. It then lists some traditional surface treatment options which can add cost, complexity or safety issues to a process before discussing two 3M acrylic structural adhesives specifically formulated to bond LSE plastics. The paper closes with a discussion of some pressure-sensitive adhesive tapes and adhesion promoters that can also be used to bond LSE surfaces.

  • This white paper discusses some major aspects of acrylic structural adhesives, including comparing acrylic structural adhesives to two-part epoxy structural adhesives, characteristics of the three major types of acrylic adhesives (MMA, Low-odor and LSE) and some characteristics of newer acrylic adhesives that make them more user-friendly in production environments.

  • This brochure reviews some of the latest 3M™ Scotch-Weld™ Structural Acrylic Adhesives and how they can enhance productivity and performance. Some of the particular advances of new formulas include faster rate of strength build, higher impact resistance, longer shelf life, easier storage and lower odors. A metal-bonding adhesive designed to withstand powder coat and paint bake processes is also described.

  • 3M acrylic structural adhesives are easy to apply and cure quickly. Explore our range of options for bonding a wide variety of substrates, including most plastics, aluminum, steel and oily metal surfaces. Many products also have low-odor and non-flammable formulations.
