3M™ Dual Lock™ Reclosable Fastener SJ3441

General Information

This product is used for alternative attachment methods it requires a unique attachment method and, based on how this product is used, the heat resistance, tensile

and shear strength can vary. This product does not have adhesive backing, so there is no release liner.

Product Family: Plain backed for hot melt, liquid adhesive or other forms of attachment.

These are typical values which were gathered from testing the PSA backed materials. Similar values can be expected when the Dual Lock is held securely in a rigid

fashion, however the data may vary depending on the attachment method used.
