3M SJ3552

3M SJ3552 has exceptional strength through its interlocking mushroom-shaped heads (170 stem density per square inch), providing up to 5X the tensile strength of typical hook-and-loop products. We designed this fastener with a white, acrylic, conformable foam tape protected by a removable, film liner.
This solid, pressure sensitive foam tape features a strong, durable bond that is heat, chemical and UV resistant.
With 3M™ Dual Lock™ Reclosable Fastener SJ3552, there is no need for any drilling, screwing or sewing tools which makes for quick installation.

Unlock simplicity, super strength, and ultimate ease. The remarkable 3M™ Dual Lock Reclosable Fastener can be opened and closed up to 1,000 times before losing 50% of its original strength, for repeated access or repositioning.
The mushroom heads easily slide over each other allowing positioning of parts before they are snapped together to create a firm fastening attachment.
When mated, the fasteners are hidden from view and leave you with an unbroken surface for a smooth, clean appearance.
