Within every 3M product that bonds, fastens and protects is at least one solution that helps reduce or eliminate process steps, limit rework, reduce waste and more during critical assembly processes. Learn more below.
A solution within a solution: 3M™ Fastener Adhesives add two-part structural adhesive strength to threaded fasteners without the need for mixing. They feature an epoxy resin suspended in microcapsules within a hardener. The normal shear force from installing threaded fasteners crushes these tiny capsules, releasing the resin and causing a chemical reaction that locks the parts together. These adhesives provide consistent and predictable torque values and do not require heat or primers for curing.
Our 3M™ Friction Shims help answer the demand for maximum power density – enhancing friction to transmit higher loads while enabling lightweight designs. This technology is ideal for steering and chassis designs that meet specifications for weight, torque, power density and efficiency of assembly. 3M™ Friction Shims reliably transmit up to 4X higher torque than conventional systems, without requiring modifications to joint design.
Our structural adhesive liquids can be applied at the Tier or OEM. They are heat-cured for hem bonding, crash-resistant bonding and replacement of mechanical fasteners in many applications. Many are formulated for longer storage and lower cure temperatures (room temperature to induction curing as low as 80°C), ideal for bonding materials like carbon fiber without distortion or resin degradation. Many substructures can be stored for weeks before final heat curing. 3M Structural Adhesive Liquids are compatible with many wet and dry lubes.
Many of our two-part epoxy structural adhesives are available in Duo-Pak cartridge and bulk containers and can be applied with 3M application equipment that allows for precise, consistent mix ratios and minimal product waste.
The power of 3M structural adhesives in a tape format makes for added precision where clean, complete application is critical and where corrosion is a main concern. These structural adhesive tapes improve quality by reducing variability of application and can bond to a variety of metal substrates. They also expand during cure to fill gaps, which can help reduce warranty claims in some applications. Structural adhesive tapes are ideal for efficient processing and assembly, especially for bonding long, thin areas where the use of spot welds or mechanical fasteners has traditionally required extra time and labor.
Approved by multiple OEMs, 3M™ Paint Protection Films begin delivering benefits well before paint. Flexible, die-cuttable and available pre-masked, these films provide reliable corrosion protection between metal parts. They feature pressure-sensitive adhesives for efficiency during assembly.
3M is constantly working to meet the evolving challenges of automotive OEM and Tier suppliers worldwide. If you need help finding an existing solution or would like to talk about specific ideas you’re working on, get in touch with us.
