Can 3M Dual Lock be used outdoors?

Yes! SJ3550 is specifically designed for outdoor use with superior UV, moisture, and temperature resistance (-20°F to 200°F), making it perfect for exterior applications like signage and vehicle accessories.

How much weight can it safely hold?

When properly installed, SJ3550 supports approximately 4.8kg/10.5lbs per 10cm² in direct tensile load. For vertical mounting, use 4 square inches per pound with a safety factor for critical applications.

Will it work on curved or uneven surfaces?

Yes! The flexible backing conforms well to moderately curved and slightly uneven surfaces. For highly textured areas, apply to the flattest sections for best results.

Does it leave residue when removed?

The interlocking mechanism separates cleanly. The adhesive is designed for permanent attachment, but can be removed using products like Goo Gone on compatible surfaces if needed.

What's the difference between Dual Lock and regular Velcro?

Dual Lock uses mushroom-shaped stems that interlock, creating 5X stronger connections than hook-and-loop. It provides an audible "snap" when engaged and maintains performance through 1000+ attachment cycles.
