3M™ Dual Lock™ Reclosable Fastener SJ3550 solves attachment issues without the use of special tools or complicated, mechanical fastening systems. Our reclosable fastener uses an acrylic adhesive that bonds well to a variety of high and medium surface energy materials, including some plastics, metal, glass, and painted surfaces. This allows you to attach access doors, panels, signs, display components, and many other frequently opened and closed parts for easy, repeated access with minimal loss of bonding strength over time. SJ3550 has 40 stems / cm² with a 5.8 mm engaged thickness.
3M™ Dual Lock™ Reclosable Fasteners are available in three stem densities to customize for the strength requirements of your project
Durable and secure, 3M™ Dual Lock™ Reclosable Fastener TB3550 has exceptional strength through its interlocking mushroom-shaped heads (250 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 TB3550, there is no need for any drilling, screwing or sewing tools which makes for quick installation.
Recommended Applications:
- Access panels
- Graphic attachment
- Specialty vehicles (interior attachments)
- General industrial attachment
- Small components
Design Flexibility
3M™ Dual Lock™ Reclosable Fastener TB3550 consists of interlocking mushroom-shaped heads that easily slide over each other, allowing for positioning of parts before being snapped together. This fastening process creates a durable attachment and provides fast product assembly with great design flexibility. Our reclosable fasteners can also engage with different stem densities for varying levels of strength and system performance.
3M Trial Bags Simplify Selection
3M™ Dual Lock™ Reclosable Fastener Trial Bags provide a simplified "go-to" selection that has proven successful for most common applications, along with just the right length (1 in. x 10 ft.) and quantity for trial run testing.
Hundreds of Reattachments in a Snap
When two pieces of 3M™ Dual Lock™ Reclosable Fasteners mate, the stems flex and the mushroom heads slide past each other. After passing the opposing mating piece, the stems snap back into their original position and the opposing mushroom heads interlock. These fasteners can provide high tensile strength but can be opened by simply cleaving or peeling open the closure. This product is well suited for many indoor and outdoor applications where a high strength and versatile reclosable fastening system is required.
Delivers Long-Lasting Performance
Not all design requirements are easily satisfied, but you can simplify your attachments. When you need a strong, reliable, yet removable closure, 3M™ Dual Lock™ Reclosable Fasteners are the easy alternative to traditional fastening methods such as screws, nuts or bolts.
