FEATURES

• Black closure system with mushroom-shaped filaments, featuring pressure-sensitive acrylic adhesive.
• Type 250 combines with type 170, 250, or 400. Closes with an audible snap.
• Five times greater tensile strength than traditional hook and loop fasteners.
• Opens and closes 1000 times before losing 50% of its original tensile strength.
• Designed to bond metals, glass, and paints and plastics with high and medium surface energy.
• The foam tape allows for better contact with textured or irregular surfaces.

BENEFITS

• Teamwork is the underlying idea behind the design of the repositionable 3M™ Dual Lock™ SJ3550 closure.
• When joined, the unique mushroom-shaped filaments interlock with each other, generating five times the closure strength of standard hook and loop fasteners while maintaining the ability to separate easily for access.
• When two pieces are pressed together, the filaments flex and the mushroom heads slide over one another.
• After coupling, the filaments return to their original position, interlocking with the opposing heads with an audible sound indicating that the system is engaged.
• This system can be opened and closed 1000 times before losing 50% of its original tensile strength.
• No drilling, screwing, or tightening is required, nor complex installations.
• The adhesive bonds quickly and reaches full strength in 72 hours. Once bonded, the interlocking mushroom-shaped filaments can withstand forces similar to screws and rivets, with the difference that they separate easily for access.
• Versatile, durable, and invisible There is no limit to the number of uses of these closure systems.
• The filaments, mushroom heads, and film backing are made of polypropylene, and the polyolefin backing resists common solvents and alkaline solutions, making them ideal for various purposes and environments.
• The SJ3550 closure systems have an acrylic foam tape with a removable protective liner.
• This construction allows for better contact with irregular surfaces or those with slight roughness.
• To achieve various levels of holding power, the system can be combined with different types of repositionable 3M Dual Lock systems.
• Among the system combinations we suggest are: Type 250 with type 170, Type 250 with type 250, Type 170 with type 400, Type 250 with type 400. For a quick-grip fastening with high resistance but limited life cycle, any of the Dual Lock products from 3M can be combined with repositionable 3M™ Hook and Loop™ fasteners.

APPLICATIONS

The repositionable closure system 3M™ Dual Lock™ SJ3550 solves fastening problems without the need for special tools or complicated mechanical fastening systems. Our repositionable closure system features an acrylic adhesive that bonds well to various materials with high and medium surface energy, including some plastics, metal, glass, and painted surfaces. This allows you to secure access doors, panels, signs, display components, and many other pieces that open and close frequently, allowing for easy and repeated access with minimal loss of adhesive strength over time.

TECHNICAL DATA

It has a density of 40 mushroom-shaped filaments/cm² with a bonded thickness of 5.7 mm, resistance to temperatures between -30 °C and 70 °C long-term (+95 °C short-term), and can be used indoors and outdoors.
