The TIZIP zipper is highly resistant to damage caused by dirt or sand. However, if dirt or sand are present, the zipper should be cleaned with soap and water. Dirt particles can affect the sealing function, if they get caught between the chain profiles. The zipper will prove its stability and durability even under most tough conditions. It is shock-proof, highly abrasion-resistant, and it will survive short-term sharp bending and twisting without separating. When closed, the zipper has a cross-breaking strength of minimum 300 N/cm. The sealing function of the zipper results in a tough movement of the slider. It is only a matter of course that it moves a little bit “harder” than regular zippers. The handle with puller allows an easy operation. Humidity or the TIZIP lubricant will improve the sliding function.
However, in the event of overstressing the zipper during closing, the chain may stay separated. The closure remains open, but the TIZIP will not be damaged by this. In this case, simply move the slider back, reduce the cross tension, and then reclose the zipper. If the zipper has opened all the way down into the bottom stop, the first min. 2 cm have to be closed by hand before the slider is pulled back.
