Frequently Asked Questions
What makes 3M Dual Lock stronger than hook-and-loop fasteners?
The Dual Lock reclosable fastener features a unique mechanical locking design with acrylic adhesive that provides up to five times the holding power of traditional hook-and-loop products. This superior strength comes from the interlocking mushroom-shaped stems that create a more secure bond while maintaining reclosability.
Can the 3M Dual Lock fastener be reused multiple times?
Yes, the reclosable design of the Dual Lock fastener allows for repeated attachment and detachment cycles without significant adhesive degradation. This makes it an economical choice for applications requiring frequent repositioning or temporary mounting solutions.
What surfaces does the MP3551/MP3552 adhere to?
The 3M Dual Lock adhesive fastener bonds effectively to metals, glass, medium to high surface energy plastics, and painted surfaces. For best results, ensure surfaces are clean and dry before application. It is not recommended for low surface energy plastics without proper surface preparation.
Is this reclosable fastener suitable for outdoor use?
Yes, the Dual Lock fastener is designed for both indoor and outdoor applications. The acrylic adhesive and polypropylene construction provide excellent weather resistance and durability in challenging environmental conditions, with reliable performance up to 200°F.
