3M Scotch SJ4570 Dual Lock Low Profile Reclosable Fasteners can replace conventional fasteners such as screws, clips, rivets, snaps, hook and loop and bolts in many applications where access or repositioning is needed. Amazingly thin and reclosable, yet strong, 3M Dual Lock Low Profile fasteners are thinner and more flexible than other reclosable fasteners. SJ4570 is backed with 3M 300 LSE Laminating adhesive, giving it an excellent bond to many substrates including polypropylene, polyethylene, metal, finished wood and many others. Used in POP (point of purchase), trade show exhibition and electronics, Dual Lock low profile reclosable fasteners attach ceiling tiles, carpet, seat cushions, trade show graphics, access panels, wall panels and small electronic devices. They are also great for attaching E-ZPass tags to car windshields. 3M typically recommends 4 square inches of fastener per pound of static load for their low profile dual lock products. The 10 foot sizes are cut from longer source rolls and come in a zip-lock bag (only the 5/8 inch x 10 foot size of SJ4570 which is specifically labeled as *retail-packaged comes in a package suitable for resale). Dual lock only has one type of side; unlike Velcro where there is a separate hook and a loop side; so rolls are typically cut in half and then mated or connected so a 10 foot roll would be used as two 5-foot strips.
* Multiple cases may be shipped per package in order to minimize the charge for shipping.

hot melt rubber (synthetic)
Offers the widest range of application flexibility available. Exhibits excellent processing performance whether manually or automatically applied. Has superior tensile strength, adhesion properties and holding force which ensures consistent, reliable seals. Hot melt adhesive will bond faster to a surface which is referred to as quick-grab or quick-stick. It typically has higher tack (will feel stickier to the touch), but is also softer. It has lower heat resistance, shear resistance, and sometimes UV resistance than an acrylic adhesive. NOTE: it is called hot melt because the adhesive is applied hot by the manufacturer and then hardens as it cools (you do not need to apply heat to the tape yourself).
natural rubber
Properties are similar to that of hot melt rubber, but natural rubber often holds where other adhesives won't (recycled fibers, dust, cold, heat and heavy loads). It provides good overall adhesion and moisture resistance.
acrylic
Offer excellent performance, especially for applications in temperatures less than 40°F and greater then 120°F. It provides excellent clarity, has high shear strength, is usually more permanent/durable even when exposed to moisture, and it ages well over extended periods in fluorescent and sunlight. Since it remains clear for the life of the application and does not yellow over time it is ideal for applications such as sealing white cartons. While it has good initial adhesion it does take 24-48 hours to cure and to achieve its maximum bond strength (has gradual adhesion buildup). Another difference between hot melt rubber and acrylic adhesive is if you fold tape over making the two adhesive sides touch the acrylic adhesive will remain attached to the carrier (e.g. paper, film) while a hot melt adhesive will stick to itself and pull off of the carrier. It is the best choice for clarity, UV resistance and aging characteristics.
silicone
Is great for extreme temperature applications since silicone adhesive can work in continuous operating temperatures from -100°F to 500°F. They also exhibit good chemical resistance, retain electrical properties, and remove cleanly with little or no residue.
zinc oxide
Zinc oxide based adhesive formula is a skin-friendly adhesive which is commonly used on sports medicine tapes.
