## Description

3M Dual Lock SJ3550A 1"×8ft Black 2 Pack Reclosable Fastener Mounting Tape Interlocking Mushroom Shaped Strong Adhesive Hook Lock Sticky Tape for Indoor and Outdoor(DB25252)

## Features

- FEATURE: Dual Lock Reclosable Fastener SJ3550 is the convenient alternative to traditional fastening methods, such as screws, nuts or bolts. It is designed to deliver a durable, reclosable fastening solution (which can be opened and closed multiple times) which bonds to a variety of substrates including metals and plastics such as acrylics, polycarbonate and ABS.
- HIGH QUALITY: Black, interlocking mushroom-shaped heads (250 stem density per square inch) provide strong, reliable and durable fastening that can be opened and closed multiple times. White, acrylic, conformable foam tape bonds well to a variety of substrates including metals and plastics such as acrylics, polycarbonate and ABS. Strong fastener secures with an audible snap, verifying closure. Features good temperature resistance of 200°F (93°C).
- APPLICATION: This SJ3550 dual lock mushroom clasp uses an acrylic adhesive to bond to a range of high surface energy materials, including some plastics, metals, glass and lacquered surfaces. It enables quick and easy installation without the need for mechanical mounting. After bonding, the interlocked mushroom stems can be fixed, spiral and rivet, but they can be easily separated and accessible to the fixed objects.
- INSTALLATION AND REMOVAL: At room temperature, approximately 50% of the ultimate strength will be achieved after 20 minutes, 90% after 24 hours and 100% after 72 hours. Spraying alcohol on the tape then it is easy to peel off. Please clean the bonding surface and do not touch the stick layer before using, if anything touched the stick layer. It will peel away.
- BOND SMOOTH SURFACE: Bonds most painted metal and plastic without surface residue or abrading. Specially formulated synthetic adhesive bonds most paints and powder coats, as well as window materials such as glass, acrylic, and polycarbonate, stone and wood.
