SJ3550CF BLACK RECLOSABLE CLOSURE 25 MM X 5 M TYPE 250 3M™ DUAL LOCK™ 1 ROLL

3M™ Dual Lock™ SJ3550CF - Black Fastener System 25 mm x 5 m

The 3M™ Dual Lock™ SJ3550CF (ID 7100279615) is a reclosable fastener designed for heavy-duty industrial applications requiring strength, durability and climate versatility.

Exclusive Features and Benefits

• Mushroom Technology (Type 250): With a density of 250 stems per square inch (approximately 40 per cm²), it ensures a strong, long-lasting bond that resists significant stress.
• High Thermal Resistance: Designed to operate over a wide temperature range, it maintains its adhesive properties up to 104°C .
• VHB™ Acrylic Adhesive: The acrylic adhesive backing provides excellent adhesion to substrates such as aluminum, stainless steel, glass and rigid plastics, while also resisting moisture and UV rays.
• Audible click confirmation: The safety of a correct fastening is guaranteed by the "click" sound when the two parts are pressed together.
• Long Service Life: The system is designed to be opened and closed up to 1,000 times before losing 50% of its original tensile strength.

Technical Specifications

• Dimensions: Width 25 mm | Length 5 meters.
• Color: Black with clear polyolefin liner.
• Backing material: Polyolefin.
• Environment of use: Indoor and outdoor.

Recommended Applications

This system is the preferred choice in sectors where aesthetics and maintainability are fundamental:

• Automotive and Transportation: Attachment of interior panels, trim and components requiring periodic inspection.
