The 3M range of trim attachment materials can be used in multiple automotive manufacturing applications to replace traditional mechanical fastening methods when attaching trim parts or sealing components. By replacing mechanical clips, wires and channels with these high performing products, significant car weight reductions can be achieved.
In addition, they can help to improve seals in areas at risk of corrosion and allow greater freedom and flexibility when it comes to design. To ensure a secure bond and a stable, easy attachment process, 3M also offers a range of surface preparation aids, primers and tabbing tapes.
To ensure an optimum bond when applying trim attachment materials, 3M offers a range of cleaning, wiping and priming products. The 3M High Performance Cloth incorporates tiny microstructures of fabric and is the key to a thorough surface clean. To improve the holding strength of an adhesive on critical surfaces, a 3M Adhesive Tape Primer should then be applied, particularly when working with difficult substrates that display the following characteristics:
- Low energy
- Strong plasticiser content
- Coated with release agent or glass (e.g. for the prevention of moisture creep)
3M primers are available in a variety of formats, including 3M™ VHB™ Surface Cleaner Sachets (known as IPA wipes) and 3M 4298 Adhesion Promoter Sponge Applicator. Specific information on these and the other products in the range can be downloaded from our Datasheets section.
For specific advice on how to clean and prepare your surface before using 3M trim attachment materials, contact a 3M Technical Service Engineer.
3M Acrylic Foam Tapes
3M™ Acrylic Foam Tapes provide a quick, efficient and reliable method of attaching trim parts or seals to a car body. Featuring a future-proof design that outperforms traditional joining technologies, they have been formulated specifically for modern automotive manufacturing.
A viable alternative to traditional mechanical fixing processes such as welding, clipping and screwing, with no requirement for specific attachment mechanisms. 3M Acrylic Foam Tapes can be applied manually or automatically.
3M™ Dual Lock™ Reclosable Fasteners
3M Dual Lock is a reclosable fastening system with high mechanical holding capability. Positive pressure engages the interlocking, mushroom-shaped hooks to grip trim parts in place quickly and securely: a 25mm² Dual Lock clip is capable of holding up to 1kg in weight, even at high temperatures. Available in a variety of thicknesses and with different attachment options, 3M Dual Lock will bridge gaps of up to 10mm wide and stick fast to critical plastic surfaces.
- A lightweight alternative to clips and screws,
- Speeds up line-side installations,
- Allows repositioning during curing phases (e.g. glazing),
- Available with self-adhesive backing or as a mechanical fitted clip,
- Can be combined with 3M adhesive tapes, or mounted onto screws or ‘pop-in’ parts.
Popular 3M Dual Lock products for the automotive manufacturing industry include 3M Dual Lock for Rollstock and Preformed Parts and Scotchmate™ Hook and Loop Fasteners. For specific details of these and the other products in the Dual Lock range, please visit our Datasheets area.
