The aging behavior of TPU-coated, waterproof zippers has been a significant focus of TIZIP’s product development for decades.

It has been mostly analyzed that TPU coating material failure, characterized by swelling, cracks, or delamination, is caused by aging (moisture, temperature, microorganisms, etc.), known as hydrolytic degradation processes. Despite various handling precautions contributing significantly to minimizing hydrolytic degradation, TIZIP has now developed a optimized TPU coating material that eliminates the typical aging behavior of TPU-coated zippers in the long term.

Especially in the watersports & diving sector, where waterproof zippers are exposed to constant moisture, the new MasterSeal #10 hydrolysis protection represents a significant advantage compared to conventional, short-lived products.

Reliable products with an outstanding quality level are the key priorities of our TIZIP brand. That‚Äôs why we are constantly working on innovative ideas and technical improvements to further enhance the already outstanding quality and durability level of our waterproof and airtight premium TIZIP zippers ‚Äď 100% made in Germany.

Be advised that TIZIP is not responsible for any malfunction or damages that may occur as a result of the use of counterfeit products and that products purchased outside of TIZIP‚Äôs authorized or trusted sales channels are not warranted by TIZIP or supported in any way.

Please have also a deeper lock at the below listed characteristic trademarks of TIZIP zippers in contrast to current copycats.
