TIZIP Masterseal#10 Drysuit Zipper – 91cm

Technical
The TIZIP MasterSeal 10 is made from high-strength fabric coated with thermoplastic polyurethane. The extra strong plastic teeth are fixed on the top and bottom of the zipper tape. The zipper’s coupling elements keep the sealing edges tightly sealed together when the zipper is closed. The zipper tape can be both welded and glued.

The TIZIP MasterSeal 10 slider is made from a metal compound which is non skin irritating and salt water resistant. The slider movement is contact free and does not wear on the zipper tape or the sealing edge.

Gluing

In order to achieve a sufficient adhesion between the zipper tape and the neoprene or trilaminate, very often a grinding process of the TPU coated tape is carried out. Please consider, that the TPU coating thickness is only a few micrometers. Grinding affects the TPU surface negatively and can lead to microscopic pinholes or cracks. Cleaning liquids and glue might diffuse into the textile leading to TPU material degradation and TPU delamination. If you think grinding cannot be avoided, please ensure that the grained areas are 100% covered by the adhesion glue, so that no water can migrate into the microscopic cracks and pinholes during zipper usage and result hydrolysis and microbiotic degradation, in the long term.

TIZIP always recommends avoiding grinding and to check out alternative glues. Insufficient adhesion of the zipper tape to the fabric can also lead to “water pockets” where water and moisture accumulate and cause material degradation.

Tightness

The TiZip  MasterSeal 10 is easy to operate, and pressure tested to 500 mbar.

Heavy bending may cause leakage. Please try to avoid.

The TiZip® Masterseal 10 offers a pressure resistance of 500 mbar and a transverse tensile strength of 200N/cm. That’s pretty intense and will withstand anything you manage to put it through. No matter how gnarly that waterfall is. Its waterproof and pressure-resistant properties are secured by the pressing together of the sealing lip across the interlocking elements. This is done with a saltwater-resistant metal slider

Dirt or Sand
The TIZIP MasterSeal 10 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. If the TIZIP MasterSeal 10 closure is used to protect life or sensitive material, the sealing function and cleanliness of the chain area should be thoroughly checked prior to every usage.

Stability
The TIZIP MasterSeal 10’s performance in terms of strength and durability is very good. However, sharp bending or twisting should be avoided.

When closed, the TIZIP MasterSeal 10 has a cross-breaking strength of minimum 125 N/cm.
