Product Overview

3M™ Dual Lock™ Reclosable Fastener SJ3552 is a premium heavy-duty, reusable fastening solution engineered as a high-strength alternative to traditional mechanical fasteners like screws, bolts, and rivets. Featuring a black polypropylene base with a high-density array of interlocking mushroom-shaped stems (400 stems per square inch, Type 400), this tape is coated with a high-performance clear acrylic pressure-sensitive adhesive, delivering instant, low-visibility bonding to a wide range of surfaces.

Core Features & Benefits

Extreme Holding Power: The Type 400 high-density mushroom stem design delivers exceptional tensile strength, up to 5 times that of standard hook-and-loop products, creating a secure, rigid bond for heavy-duty applications.
Reusable & Durable: Engineered to withstand over 1,000 open/close cycles while maintaining consistent performance, ideal for applications requiring frequent access and long-term reliability.
Low-Visibility, Clean Bond: The clear acrylic adhesive eliminates unsightly white residue, providing a seamless, finished look for visible applications.
Easy, Tool-Free Installation: Pressure-sensitive adhesive allows for quick application without drilling or tools. Simply peel the liner and apply to clean, dry surfaces.
