The 3M™ Dual Lock™ Reclosable Fastener DL400/468MP, 10mm x 20mm provides an aesthetically pleasing, unbroken surface without the use of unsightly mechanical fasteners. Our fastener comes with 3M™ Adhesive Transfer Tape 468MP and is backed with a paper liner. This clear, 5 mil adhesive provides excellent shear strength, temperature and chemical resistance.

3M™ Adhesive Transfer Tape 468MP provides excellent solvent resistance and shear resistance and exhibits excellent adhesion to metal and high surface energy plastics.
Different stem densities allow for mixing and matching, achieving the engagement and disengagement forces needed for the application
Reliable Attachment, Over and Over
Designed with hundreds of interlocking mushroom-shaped stems, this fastener offers strong, fast and easy attachment for automotive assembly applications. This polypropylene reclosable fastener is coated with a clear acrylic adhesive on the back to provide an excellent bond after full adhesion. The interlocking mushroom-shaped heads deliver exceptional tensile strength and can be easily attached and detached multiple times. Featuring temperature, moisture and UV resistance, this reclosable fastener offers reliable durability and is designed to help reduce vibration for satisfying, long-term performance. In addition, this unique fastener secures with an audible snap to help confirm closure verification.

Adhesive Performance
3M™ Adhesive Transfer Tape 468MP provides excellent solvent resistance and shear resistance and exhibits excellent adhesion to metal and high surface energy plastics. This adhesive provides some initial repositionability for placement accuracy when bonding to plastics. It also performs well after exposure to humidity and hot/cold cycles.

An Advanced Closure Alternative
When two pieces of 3M™ Dual Lock™ Reclosable Fasteners are pressed together, the stems flex, allowing the mushroom heads slide past each other and the opposing mushroom heads interlock. These fasteners provide high tensile strength but can be opened by simply cleaving, or peeling open the closure.

Alignment and re-alignment are easy and no special tools are required for installation. This means that Dual Lock fasteners can be used to attach components before they enter the final assembly plant, helping to reduce the number of parts and assembly time.

This product is well suited for many applications where a high strength, reclosable fastening system is required. Many 3M™ Dual Lock™ Reclosable Fastener products have good performance even aft er exposure to high moisture levels and wide temperature ranges.
