3M High Strength Adhesive Mushroom Hook and Loop Fastener Tape SJ3550 with 250 SPI and Acrylic Foam Backing

3M High Strength Adhesive Mushroom Hook and Loop Fastener Tape delivers exceptional holding power with its innovative reversible design and superior adhesive backing system.

• Reversible Design: Works equally well on both hook and loop sides for seamless interlocking
• Exceptional Strength: Exceeds standard nylon hook-and-loop fasteners by more than 5 times
• Mushroom Hook Technology: Provides superior durability and reliability in demanding applications
• Advanced Adhesive System: Acrylic foam backing with increasing bond strength over time

The mushroom-shaped hook fasteners provide variable holding power based on stitch density, with the SJ3550 model featuring 250 SPI for optimal balance of strength and flexibility.

The acrylic foam adhesive exhibits initial low tackiness that gradually increases over time, ensuring stronger and more secure bonds as it cures. This makes it ideal for applications requiring long-lasting adhesion under varying conditions.
