3M SJ3550 Dual Lock Reclosable Fastener, Adhesive Backed, 25 mm x 45.7 m

Manufacturer code: 601. Brand: 3M. Reclosable fastener tape SJ3550, adhesive-backed, 25 mm x 45.7 m. Black mushroom-shaped mechanical fastener bodies supported by an acrylic pressure-sensitive adhesive. Type 250; mates with Type 170, 250 or 400. Closes with an audible snap. Provides up to five times the peel strength of typical hook-and-loop fasteners. Can be opened and closed 1000 times before losing 50% of original shear strength. Designed to adhere to metals, glass, and medium- to high-surface-energy plastics and painted surfaces. Foam-backed tape conforms better to textured or irregular surfaces. The tape contains 40 mushroom-shaped stems per cm² (250 per in²). When pressed together the stems flex and their heads interlock; the interlocked heads snap audibly and return toward their original shape. Uses an acrylic adhesive that bonds well to various medium- and high-surface-energy substrates; adhesive attains full strength after 72 hours. No drilling, screwing or complex installation required.
