3M™ Dual Lock™ Reclosable Fastener SJ3445

General Information

This product for alternative attachment methods 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: Non-Woven backing for hot melt or other liquid adhesive attachment

Typical Performance Characteristics

Temperature Use Range note

Typical temperature performance for Dual Lock products with no adhesive backing on them while supporting 2.2 lbs/ in2 (1.0 kg/in2) in tensile or shear loads would

range from -20°F to 220°F (-12°C to 104°C). This may change depending on the attachment method used, for example if you use an adhesive to attach the Dual Lock

to a substrate the temperature resistance of the adhesive most likely will dictate the overall performance.

Note

The following technical information and data is intended as a guideline to assist customers in selecting 3M™ Reclosable Fasteners for further evaluation. This technical

information is not product release speci cations or standards. Unless stated di erently, the typical system performance and product properties were obtained using

speci c test methods under controlled laboratory conditions of 72°F

± 5°F and 50% ± 10% relative humidity. The user is responsible for evaluating 3M reclosable fasteners under expected use conditions to ensure suitable performance

for the intended application.

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.
