3M™ Dual Lock™ Reclosable Fastener DL400/PX5011 is a black polyolefin reclosable fastener with a dark gray ZX primerless acrylic pressure sensitive adhesive, designed for automotive trim attachment applications where secure fastening, reclosable access, and reliable adhesive performance are required. The fastener features mushroom-shaped polyolefin stems that engage with firm pressure to create a positive-locking mechanical closure. This allows components to be securely attached while still enabling them to be opened and re-closed for service access, maintenance, or replacement. The ZX primerless acrylic adhesive has an adhesive thickness of 1.1 mm and is designed to support adhesive-backed attachment without the need for a separate primer step in suitable applications. With a total unmated thickness of 3.8 mm and a tolerance of +/- 0.5 mm, 3M™ Dual Lock™ Reclosable Fastener PX5011 offers a thicker adhesive-backed option for applications where bond-line performance and process efficiency are important. The product is available in DL170, DL250, and DL400 stem density types, allowing engineers to select different engagement and disengagement force levels depending on application requirements. It supports hidden attachment on the rear side of trim components, helping maintain uninterrupted show surfaces while providing reclosable functionality for automotive assembly applications.
