-
How strong is the bond of 3M™ Dual Lock™ Reclosable Fastener SJ3441?
The bond strength of The 3M™ Dual Lock™ Reclosable Fastener SJ3441 is dependent on several factors such as substrate type, temperature conditions and surface energy. To achieve maximum adhesion between two surfaces bonding should occur when room temperature and sufficient pressure applied with interlocking strips for no less than one minute at room temperature (+20°C/68°F).
-
Can I reuse the reclosables or are they only good for one use?
Yes! One of the key benefits of this product is its ability to be opened and closed multiple times while still maintaining a secure hold. This makes it ideal for situations where items need to be frequently accessed or removed often; you don’t have to worry about damaging either side because there aren't any hooks or loops that could potentially be damaged by continued use.
Durable and secure, 3M™ Dual Lock™ Reclosable Fastener SJ3441 has exceptional strength through its interlocking mushroom-shaped heads (400 stem density per square inch). With 3M™ Dual Lock™ Reclosable Fastener SJ3441, there is no need for any drilling or screwing. This fastener is most commonly attached by applying hot melt, epoxy or liquid adhesive.
Recommended Applications:- Alternative to pressure sensitive adhesives
3M™ Dual Lock™ Reclosable Fastener SJ3441 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. 3M reclosable fasteners can also engage with different stem densities for varying levels of strength and system performance.
3M™ Dual Lock™ Reclosable Fasteners sound an audible snap when secure, which verifies closure of the attachment. To disengage, simply peel the pieces apart by hand. 3M fasteners maintain their strength throughout multiple attachments and detachments. A lightweight alternative to metal fasteners, this product remains hidden beneath surfaces and does not interfere with the integrity of your material—providing aesthetic improvements and design flexibility.
Hundreds of Reattachments in a SnapWhen 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 applications where a good performance, high strength, reclosable fastening system is required.
Delivers Long-Lasting PerformanceNot 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.
